    Before TYMKOVICH, Chief Judge, BACHARACH, and CARSON, Circuit
    Judges.
    TYMKOVICH, Chief Judge.
    Following the January 2016 death of Ricardo Jose Ortiz at the Sante Fe
    Adult Detention Facility (ADF), Ortiz’s personal representatives sued multiple
    individual ADF affiliates, alleging state claims under the New Mexico Tort
    Claims Act and violations of his Fourteenth Amendment right to medical
    treatment under 
    42 U.S.C. § 1983
    . The defendants moved to dismiss the first
    amended complaint (FAC), and the plaintiffs moved to amend their complaint to
    include a claim for municipal liability that was not in any prior complaint. In an
    order addressing both motions, the district court dismissed the § 1983 claims,
    denied the plaintiffs leave to amend to include that municipal liability claim, and
    remanded the state-law claims.
    -2-
    On appeal, the plaintiffs-appellants argue the district court erred in
    dismissing the § 1983 claims against individual prison employees and in denying
    leave to amend.
    We agree that the plaintiffs-appellants plausibly alleged Officer Chavez
    violated Ortiz’s clearly established constitutional right to medical care for acute
    symptoms related to his withdrawal from heroin. But we cannot conclude they
    plausibly alleged the other individual defendants violated Ortiz’s clearly
    established constitutional right to medical care under these circumstances.
    Therefore, we VACATE the district court’s dismissal with regard to Officer
    Chavez but AFFIRM with regard to the other individual defendants.
    Separately, we conclude the district court should not have denied the
    plaintiff leave to amend for reasons of futility. The district court determined that
    the plaintiff could not state a claim for municipal liability without first properly
    stating a claim against an individual, but our court’s precedent allows municipal
    liability even where no individual liability exists.
    We accordingly VACATE the district court’s denial of leave to amend.
    I. Background
    Ortiz was arrested and booked into ADF on January 4, 2016. After
    booking, Defendant Nurse Anne Robinson conducted a medical intake exam,
    apparently without completing various intake forms. During the exam, Nurse
    -3-
    Robinson determined that Ortiz was dependent on heroin and would likely
    undergo withdrawal. She therefore offered Ortiz a set of medications known as a
    “kick kit.” The plaintiffs allege the kick kit was never administered.
    The other individual defendants—Corporal Gallegos and Officers Chavez,
    Valdo, Lopez, and Garcia—supervised or interacted with Ortiz in some capacity
    between his medical exam on January 4 and his death on January 7. By their own
    admission, they were aware that Ortiz was experiencing withdrawal symptoms.
    They did not attempt to provide any further medical assistance, and Ortiz did not
    request any further treatment.
    On January 7, Officer Garcia found Ortiz unresponsive and disrobed in his
    cell, the floors and walls of which were partially covered in feces and bodily
    fluids. Attempts to revive him were unsuccessful. Following an autopsy, it was
    concluded that Ortiz “died of an acute gastrointestinal hemorrhage due to
    probable heroin withdrawal.” App., Vol. 1 at 34.
    In January 2018, the plaintiffs filed a law suit in New Mexico state court,
    alleging a claim under the New Mexico Tort Claims Act and a claim against only
    Nurse Robinson under § 1983 for deliberate indifference to Ortiz’s serious
    medical needs. The case was removed to federal district court, and the plaintiffs
    filed the FAC, which included claims against all the individual defendants under
    § 1983. Soon thereafter, the defendants filed a motion to dismiss the § 1983
    -4-
    claims on qualified immunity grounds. The plaintiffs opposed that motion and
    moved for leave to file a second amended complaint (SAC).
    In their motion to amend, the plaintiffs explained that they wanted to make
    several material changes to their complaint. The most significant proposed
    amendment was an entirely new claim against Sante Fe County for municipal
    liability under Monell v. Dep’t. of Soc. Servs., 
    436 U.S. 658
     (1978). The SAC
    also contained amendments to the preexisting claims. According to the motion to
    amend, the SAC was meant, in part, to address the defendants’ concerns regarding
    the state-law and § 1983 claims. But the motion said that the changes to the
    § 1983 allegations were not material, as the claims were fully stated in the FAC.
    App., Vol. 1 at 135 (stating the rewritten paragraphs attempting to state claims
    against the individual defendants “contain only allegations previously set forth in
    the operative [i.e. First Amended] Complaint”).
    The district court granted in full the defendants’ motion to dismiss the
    § 1983 claims based on qualified immunity. In the same order, the court also
    denied the motion to amend because the proposed SAC would not have cured the
    various deficiencies in the § 1983 claim and because it did not properly state a
    Monell claim as a matter of law. Having disposed of the various federal questions
    giving rise to the district court’s subject matter jurisdiction, the court remanded
    the surviving state-law issues to state court.
    -5-
    II. Discussion
    A. Qualified Immunity
    Our qualified-immunity inquiry requires a plaintiff to allege that: (1) the
    defendant violated a constitutional right and (2) the constitutional right was
    clearly established at the time of the violation. E.g., Lindsey v. Hyler, 
    918 F.3d 1109
    , 1113 (10th Cir. 2019) (citing Medina v. Cram, 
    252 F.3d 1124
    , 1128 (10th
    Cir. 2001)). We have described this burden as “heavy,” in large part because our
    qualified-immunity inquiry “is designed to spare a defendant not only
    unwarranted liability, but [also] unwarranted demands customarily imposed upon
    those defending a long drawn-out lawsuit.” Medina, 
    252 F.3d at 1128
     (quoting
    Wilson v. Layne, 
    526 U.S. 603
    , 609 (1999) (quotation marks omitted)).
    Here, the plaintiff has failed to allege plausibly a clearly established
    constitutional violation against any of the six individual defendants other than
    Officer Chavez.
    In making that determination, we look to the FAC and not the proposed
    SAC. As we explain below, a de novo review reveals the district court should not
    have denied the plaintiffs’ motion to amend the complaint to add a separate claim
    against the county for municipal liability. The district court did not, however, err
    in denying the motion with regard to allegations against the various individual
    plaintiffs.
    -6-
    As that court noted, the plaintiffs specifically argued in their motion to
    amend that their proposed amendments to Count II—i.e. the count alleging
    individual liability—were not “substantive amendments,” clarifying that “while
    the paragraphs under Count II are partly rewritten, they contain only allegations
    previously set forth in the operative complaint.” App., Vol. 1 at 135. That is, the
    plaintiffs themselves explicitly denied that the SAC would in any way cure
    deficiencies in the FAC with respect to the allegations in Count II. The district
    court was under no obligation to consider an argument that the movant not only
    did not raise but explicitly discredited and disowned.
    Because any argument that the district court erred in denying the motion to
    amend with regard to Count II of the complaint is waived, we do not consider the
    allegations made in the SAC as opposed to the allegations made in the FAC.
    1. Constitutional Violation
    In assessing the plaintiff’s contention that the individual defendants
    violated Ortiz’s Fourteenth Amendment rights, we apply the two-part Eighth
    Amendment inquiry when a pretrial detainee alleges deliberate indifference to
    serious medical needs. 1 E.g., Martinez v. Beggs, 
    563 F.3d 1082
    , 1088 (10th Cir.
    2009) (citing Garcia v. Salt Lake Cty., 
    768 F.2d 303
    , 307 (10th Cir. 1985)). This
    1
    We also endorse Judge Bacharach’s rejection of the argument that
    Kingsley v. Hendrickson, 
    135 S. Ct. 2466
     (2015), requires us to conduct only an
    objective inquiry.
    -7-
    exercise requires both an objective and a subjective inquiry. 
    Id.
     (citing Callahan
    v. Poppell, 
    471 F.3d 1155
    , 1159 (10th Cir. 2006)).
    The objective inquiry asks whether “the harm suffered rises to a level
    sufficiently serious to be cognizable under the Cruel and Unusual Punishment
    Clause of the Eighth Amendment.” 
    Id.
     (quoting Mata v. Saiz, 
    427 F.3d 745
    ,
    752–53 (10th Cir. 2005) (quotation marks omitted)). The subjective inquiry, in
    turn, asks whether “the defendants knew [the detainee] faced a substantial risk of
    harm and disregarded that risk, by failing to take reasonable measures to abate it.”
    
    Id.
     (quoting Callahan, 
    471 F.3d at 1159
     (quotation marks omitted)).
    a. Objective Inquiry
    As we have observed, “[a] medical need is sufficiently serious ‘if it is one
    that has been diagnosed by a physician as mandating treatment or . . . is so
    obvious that even a lay person would easily recognize the necessity for a doctor’s
    attention.’” Sealock v. Colorado, 
    218 F.3d 1205
    , 1209 (10th Cir. 2000) (quoting
    Hunt v. Uphoff, 
    199 F.3d 1220
    , 1224 (10th Cir. 1999)). No Tenth Circuit
    authorities have concluded that heroin withdrawal presents a “sufficiently
    serious” medical need. 2 But the absence of precedent “on all fours” need not
    2
    Looking primarily to out-of-circuit authorities, Judge Bacharach’s
    opinion fashions a reasonable case that symptoms associated with heroin
    withdrawal present a “sufficiently serious” medical need. We do, however, note
    that three of these cases deal with alcohol withdrawal. See Lancaster v. Monroe
    (continued...)
    -8-
    foreclose this conclusion. We assume—without deciding this question—that the
    severe opioid withdrawal Ortiz experienced does satisfy our requirements for a
    “sufficiently serious” medical need. We now turn, then, to whether the plaintiffs
    alleged the individual defendants knew that Ortiz was experiencing such serious
    withdrawal and disregarded that fact.
    b. Subjective Inquiry
    With respect to the subjective component of our Eighth Amendment
    inquiry, we begin by noting the Supreme Court has insisted upon actual
    knowledge: “the official must both be aware of facts from which the inference
    could be drawn that a substantial risk of serious harm exists, and he must also
    draw the inference.” Farmer v. Brennan, 
    511 U.S. 825
    , 837 (1994) (emphases
    added). It is true a “factfinder may conclude that a prison official knew of a
    substantial risk from the very fact that the risk was obvious.” 
    Id. at 842
    . But our
    precedent effectively cabins this exception by requiring that such risks present
    themselves as “obvious” to the so-called “reasonable man.” See Mata, 
    427 F.3d at
    752 (citing Garrett v. Stratman, 
    254 F.3d 946
    , 950 (10th Cir. 2001)).
    2
    (...continued)
    Cty., 
    116 F.3d 1419
    , 1425 (11th Cir. 1997); Thompson v. Upshur Cty., 
    245 F.3d 447
    , 457 (5th Cir. 2001); Caiozzo v. Koreman, 
    581 F.3d 63
    , 72 (2d Cir. 2009).
    The fourth addresses withdrawal from methadone. See Foelker v. Outagamie
    Cty., 
    394 F.3d 510
    , 511–13 (7th Cir. 2005).
    -9-
    We have previously held that unconsciousness presents such an “obvious”
    risk. See Garcia, 
    768 F.2d at 308
    . We have likewise held that “a gangrenous
    hand or a serious laceration” would also present an “obvious” risk. See Self v.
    Crum, 
    439 F.3d 1227
    , 1232 (10th Cir. 2006) (citing Oxendine v. Kaplan, 
    241 F.3d 1272
    , 1279 (10th Cir. 2001)). But—in the case whose circumstances most nearly
    match those of this case—we have held that “characteristics . . . common to many
    intoxicated individuals” do not present an “obvious” risk. See Martinez, 
    563 F.3d at 1091
    .
    In our view, frequent vomiting alone does not present an obvious risk of
    severe and dangerous withdrawal. See 
    id.
     For clarity, as further explained below,
    we agree that the bloody vomiting Officer Chavez allegedly knew of does present
    an obvious risk. After all, blood would imply to a reasonable detention official
    that there is an actual internal injury. But since the complaint limits this
    allegation to Officer Chavez, we see no reason to export allegations of this
    knowledge onto the other individual defendants.
    With this framework in mind, we consider whether the complaint plausibly
    alleges that the six individuals at issue—Officer Chavez, Officer Valdo, Nurse
    Robinson, Officer Lopez, Officer Garcia, and Corporal Gallegos—knew that Ortiz
    “faced a substantial risk of [serious] harm and disregarded that risk, by failing to
    -10-
    take reasonable measures to abate it.” See 
    id. at 1088
     (quoting Callahan, 
    471 F.3d at 1159
     (quotation marks omitted)).
    i. Officer Chavez
    According to the FAC, Officer Chavez observed Ortiz on January 4 when
    the latter “appeared sick and vomited numerous times.” App., Vol. 1 at 27. The
    FAC further alleges: “Mr. Ortiz informed Officer Chavez that he was withdrawing
    from heroin and was ‘throwing up blood.’” 
    Id.
     The presence of blood in vomit
    makes the presence of a serious medical need more plausible and more obvious.
    In our view, taking the allegations as true, a jury could conclude the seriousness
    of the medical risks associated with vomiting blood would be obvious to any
    reasonable observer. See Mata v. Saiz, 
    427 F.3d at
    752 (citing Garrett, 
    254 F.3d at 950
    ).
    ii. Officer Valdo
    The complaint alleges Officer Valdo met with Ortiz approximately one day
    after arriving at ADF in order to assign him a housing unit. It further alleges that,
    at the time of the meeting, Ortiz appeared “severely ill” and requested to be
    housed in “safe keeping.” App., Vol. 1 at 28. The complaint does not suggest
    what symptoms Ortiz was exhibiting that would have made Officer Valdo suspect
    he was “severely ill,” nor does it explain how a request for being housed in “safe
    keeping” implies a medical need. Given the sparsity of the allegations, we cannot
    -11-
    conclude the FAC plausibly alleged that Officer Valdo knew that Ortiz “faced a
    substantial risk,” let alone disregarded it.
    iii. Nurse Robinson
    The complaint alleges that Nurse Robinson knowingly disregarded a
    substantial risk of serious harm because she conducted a deficient intake and
    failed to implement a withdrawal protocol for Ortiz. But so, too, does it
    acknowledge that Nurse Robinson offered Ortiz a kick kit, which contained
    medication selected to mitigate symptoms associated with withdrawal.
    Although the complaint also alleges that Ortiz never received these
    medications, it does not allege that Nurse Robinson was responsible for this
    failure. Under current law, we do not believe the risk posed by these
    circumstances would have been obvious to Nurse Robinson.
    We accordingly conclude the complaint does not plausibly allege that Nurse
    Robinson disregarded a substantial risk of serious harm to Ortiz.
    iv. Officer Lopez
    The complaint alleges only that Officer Lopez knew Ortiz had vomited in
    his cell and exhibited other common signs of withdrawal. Absent something
    more—like knowledge of bloody vomit—the complaint does not plausibly allege
    deliberate indifference to serious withdrawal. See Martinez, 
    563 F.3d at 1091
    (concluding that “characteristics . . . common to many intoxicated individuals”
    -12-
    were not “obvious symptoms indicating a risk of serious harm”). We accordingly
    conclude the complaint does not plausibly allege that Officer Lopez disregarded a
    substantial risk of serious harm to Ortiz.
    v. Officer Garcia
    The complaint alleges neither that Officer Garcia actually saw Ortiz in
    distress nor that Ortiz ever sought medical assistance from Officer Garcia. We
    accordingly conclude the complaint does not plausibly allege that Officer Garcia
    disregarded a substantial risk of serious harm to Ortiz. 3
    vi. Corporal Gallegos
    In much the same vein, the complaint details no specific allegations
    regarding Corporal Gallegos’s awareness of Ortiz’s illness. Nor can we impute
    actual knowledge of Ortiz’s medical needs upon Corporal Gallegos from the
    complaint’s spare observation that he heard Ortiz “pushing” and “making noises”
    on the toilet. We accordingly conclude the complaint does not plausibly allege
    that Corporal Gallegos disregarded a substantial risk of serious harm to Ortiz.
    *      *   *
    3
    The dissent contends that Ortiz’s death—which transpired 25 minutes
    after the complaint alleges Officer Garcia had seen him last—“was neither quick
    nor quiet,” and that his “medical distress would have been obvious.” Bacharach
    Op. at 30. The complaint, however tells us only that Ortiz died from a massive
    internal hemorrhage. Absent some legal or medical authority that indicates
    otherwise, speculation alone cannot impute knowledge of a constitutional
    dimension upon Officer Garcia.
    -13-
    In sum, the complaint does not plausibly allege that Officer Valdo, Nurse
    Robinson, Officer Lopez, Officer Garcia, or Corporal Gallegos consciously
    disregarded Ortiz’s serious medical needs.
    2. Clearly Established Law
    We next consider whether any plausibly alleged constitutional violations
    satisfy our rigorous standards for “clearly established” law. Officer Chavez’s
    alleged conduct did violate clearly established law. Conversely, even if the
    complaint had properly alleged constitutional violations against the other
    individuals, we would still conclude the relevant violations nonetheless failed to
    satisfy our standards.
    The Supreme Court has explained “[a] clearly established right is one that
    is sufficiently clear that every reasonable official would have understood that
    what he is doing violates that right.” Mullenix v. Luna, 
    136 S. Ct. 305
    , 308
    (2015) (citations and quotation marks omitted). Although we need not “require a
    case directly on point,” it is nonetheless the case that “existing precedent must
    have placed the statutory or constitutional question beyond debate.” 
    Id.
     (citations
    and quotation marks omitted).
    This requirement reflects the Court’s recognition that qualified immunity is
    meant to “protect[] all but the plainly incompetent or those who knowingly violate
    the law.” 
    Id.
     (citations and quotation marks omitted). The Supreme Court has
    -14-
    “repeatedly told courts . . . not to define clearly established law at a high level
    of generality.” 
    Id.
     (citations and quotation marks omitted). And the Court has
    likewise emphasized “[t]he dispositive question is whether the violative nature of
    particular conduct is clearly established.” 
    Id.
     (citations and quotation marks
    omitted) (emphasis in original). Such an inquiry “must be undertaken in light of
    the specific context of the case, not as a broad general proposition.” 
    Id.
     (citations
    and quotation marks omitted).
    The plaintiff contends “the fact that the officials were shown to have
    disregarded the plaintiff’s serious medical need was sufficient to establish that
    they knew they violated [his] rights.” Aplt. Br. 43. Bearing in mind the Supreme
    Court’s insistence upon both specificity and fair notice, we disagree. See
    Mullenix, 
    136 S. Ct. at 308
    . Where prior cases establish the “obviousness” of a
    medical need, conscious disregard of that need alone may suffice. But as we
    discussed above, the only individual defendant who consciously disregarded
    Ortiz’s serious medical need was Officer Chavez.
    a. Nurse Robinson
    We have held that need for medical treatment is “obvious” when “a medical
    professional completely denies care although presented with recognizable
    symptoms which potentially create a medical emergency.” Self, 
    439 F.3d at 1232
    .
    But the complaint never alleges that Nurse Robinson was presented with
    -15-
    recognizable symptoms that might create a medical emergency. Nor does it
    contend that she completely denied Ortiz care.
    Upon intake, the complaint alleges Ortiz informed Nurse Robinson that he
    would suffer withdrawal from his heroin addiction. The complaint does not
    allege he presented any symptoms of illness to Nurse Robinson, let alone
    symptoms that might indicate a medical emergency. Moreover, the complaint
    concedes she offered to provide Ortiz with a kick kit, which contained a number
    of medications designed to ameliorate the symptoms associated with withdrawal.
    Although—for reasons that remain unclear—he never received this medication,
    we cannot read the complaint to conclude that Nurse Robinson completely denied
    Ortiz necessary medical care.
    In the absence of authorities that would alert Nurse Robinson to the fact
    that her failure to complete all intake forms and her apparent failure to ensure
    Ortiz actually received the kick kit amounted to a violation of Ortiz’s
    constitutional rights, we conclude the complaint does not plausibly allege that she
    breached clearly established law.
    b. Corporal Gallegos and Officers Valdo, Lopez, and Garcia
    No Tenth Circuit authorities support the conclusion that Officer Valdo,
    Officer Lopez, Officer Garcia, and Corporal Gallegos violated Ortiz’s clearly
    established right to medical treatment. Nor can we read out-of-circuit authorities
    -16-
    that address medical conditions other than withdrawal from heroin to place the
    lawfulness of their conduct “beyond debate.” See Mullenix, 
    136 S. Ct. at 308
    . 4
    No authority, in our view, clearly establishes with the requisite degree of
    specificity that the officers violated Ortiz’s constitutional right to medical care
    for symptoms associated with heroin withdrawal. See 
    id.
     (emphasizing that “[t]he
    dispositive question is whether the violative nature of particular conduct is
    clearly established”(emphasis in original) (quotation marks omitted)). In the
    absence of such authorities, we conclude the complaint does not plausibly allege
    Corporal Gallegos or Officers Valdo, Lopez or Garcia breached clearly
    established law.
    4
    The dissent cites (1) Taylor v. Hughes, 
    920 F.3d 729
    , 733 (11th Cir.
    2019), where the Eleventh Circuit denied summary judgment where guards
    withheld treatment from a detainee who claimed he had been hit by a car prior to
    his arrest; and (2) Westlake v. Lucas, 
    537 F.2d 857
    , 859 (6th Cir. 1976), where
    the Sixth Circuit denied a motion to dismiss when guards denied an inmate
    treatment for a bleeding ulcer. In our view, neither case provides fair notice that
    frequent vomiting alone constitutes a serious medical need. Nor does the Eighth
    Circuit’s decision in Vaughn v. Gray, 
    557 F.3d 904
    , 909 (8th Cir. 2009), where
    prison officials had mistakenly attributed a detainee’s repeated vomiting to the
    ingestion of shampoo, rather than the heart attack that ultimately killed him.
    Although this decision might clearly establish a constitutional right to medical
    care for repeated vomiting, no matter the cause, within the Eighth Circuit, we
    cannot endorse the suggestion that one out-of-circuit authority has “placed [this]
    statutory or constitutional question beyond debate.” See Mullenix, 
    136 S. Ct. at 308
     (citations and quotation marks omitted).
    -17-
    c. Officer Chavez
    That said, Officer Chavez’s conduct did violate clearly established law by
    consciously disregarding obvious symptoms not just of heroin withdrawal but of a
    serious internal injury. Far before Officer Chavez interacted with Ortiz, we held
    “[t]he relevant, dispositive inquiry in determining whether a right is clearly
    established is whether it would be clear to a reasonable officer that his conduct
    was unlawful in the situation he confronted.” Holland v. Harrington, 
    268 F.3d 1179
    , 1186 (10th Cir. 2001) (quotation marks omitted). And we had held that
    “[a] prison official’s deliberate indifference to an inmate’s serious medical needs
    is a violation of” the detainee’s rights. Mata, 
    427 F.3d at 745
    ; see also Sealock,
    
    218 F.3d at 1210-11
     (holding a prison officer plausibly violated a detainee’s
    rights by not addressing the detainee’s symptoms even when he knew they might
    be related to a heart attack). Thus, prior to January 2016, it was clearly
    established that when a detainee has obvious and serious medical needs, ignoring
    those needs necessarily violates the detainee’s constitutional rights. Officer
    Chavez’s inaction in the face of Ortiz’s bloody vomiting therefore violated clearly
    established law.
    B. Leave to Amend
    Finally, we consider whether the district court properly rejected the
    plaintiffs’ request for leave to amend the complaint. We review the district
    -18-
    court’s denial of leave to amend for an abuse of discretion. Cohen v. Longshore,
    
    621 F.3d 1311
    , 1313 (10th Cir. 2010). Although district courts enjoy discretion,
    they “should freely give leave when justice so requires.” Fed. R. Civ. P. 15(a)(2);
    Curley v. Perry, 
    246 F.3d 1278
    , 1284 (10th Cir. 2001) (reiterating that courts
    should grant leave to amend when an amended complaint could “yield a
    meritorious claim”). Thus, “when denial is based on a determination that
    amendment would be futile, our review for abuse of discretion includes de novo
    review of the legal basis for the finding of futility.” Miller ex rel. S.M. v. Bd. of
    Educ. of Albuquerque Pub. Sch., 
    565 F.3d 1232
    , 1249 (10th Cir. 2009).
    In this case, the plaintiffs sought leave to amend to add a Monell claim
    under § 1983 against Santa Fe County for its allegedly deficient medical intake
    protocol. See Monell, 
    436 U.S. at 690
     (providing that plaintiffs may sue local
    governing bodies directly under § 1983 for constitutional violations pursuant to a
    body’s policy, practice, or custom). The district court concluded that amendment
    would be futile because the plaintiffs could not state a Monell claim without a
    viable claim against an individual defendant. But that blanket justification does
    not square with circuit precedent holding that municipal liability under Monell
    may exist without individual liability. 5 Garcia v. Salt Lake Cty., 
    768 F.2d 303
    ,
    5
    We determine above that the complaint plausibly alleges only that Officer
    Chavez—who had nothing to do with intake protocol—violated Ortiz’s clearly
    established right to medical treatment.
    -19-
    310 (10th Cir. 1985) (“Monell does not require that a jury find an individual
    defendant liable before it can find a local governmental body liable.”). Indeed,
    we concluded in Garcia that even where “the acts or omissions of no one
    employee may violate an individual’s constitutional rights, the combined acts or
    omissions of several employees acting under a governmental policy or custom
    may violate an individual’s constitutional rights.” 
    Id.
     Thus, in light of Garcia,
    the district court’s legal basis for its finding of futility is contrary to our circuit’s
    precedent.
    But that does not end the inquiry. Although the district court’s finding of
    futility is not consistent with Garcia, the proposed amended complaint must still
    allege facts that, under Garcia and Monell, plausibly state a cause of action
    against Santa Fe County. To state a claim against the County, the plaintiffs must
    allege facts showing: (1) an official policy or custom, (2) causation, and (3)
    deliberate indifference. Schneider v. City of Grand Junction Police Dep’t, 
    717 F.3d 760
    , 769 (10th Cir. 2013). The plaintiffs’ proposed amendment alleges: (1)
    Santa Fe County maintained an unconstitutional custom of failing to treat
    detainees for withdrawal, which resulted in a deficient medical intake protocol,
    (2) that custom caused Ortiz’s injury, and (3) the County’s actions (or inaction)
    stemmed from deliberate indifference. Although we are not sure whether the
    plaintiffs can prove each of those elements at trial or even survive summary
    -20-
    judgment, they allege sufficient facts supporting each element for their claim to
    proceed past the motion-to-dismiss stage.
    The plaintiffs pleaded facts indicating that Ortiz never received or did not
    take the kick kit withdrawal medications. That allegation supports the plaintiffs’
    claim that the jail had a process problem—even though we cannot pin the failure
    to administer the kick kit on any one individual. The plaintiffs also pleaded that
    three other inmates at the same jail recently experienced withdrawal-related
    deaths. And a 2003 Department of Justice study put Santa Fe County on notice
    about deficiencies in the jail’s “intake medical screening, assessment, and referral
    process.” App., Vol. 1 at 183–84. The plaintiffs further allege that these
    deficiencies contributed to Ortiz’s death. Finally, the plaintiffs alleged that the
    jail previously provided Ortiz with deficient intakes over the course of eight
    separate incidents of incarceration at the jail. Altogether, the allegations of
    intake failures preceding Ortiz’s death and past process failures sufficiently state
    a Monell claim at this early stage in the proceedings. See Barney v. Pulsipher,
    
    143 F.3d 1299
    , 1307 (10th Cir. 1998) (“The deliberate indifference standard may
    be satisfied when the municipality has actual or constructive notice that its action
    or failure to act is substantially certain to result in a constitutional violation, and
    it consciously or deliberately chooses to disregard the risk of harm.”). Thus, we
    conclude that the proposed amendment would not be entirely futile in this case.
    -21-
    Of course, we cannot determine from the face of the proposed amendment
    whether the plaintiffs will be able to substantiate their Monell claim. But “a well-
    pleaded complaint may proceed even if it strikes a savvy judge that actual proof
    of those facts is improbable, and that a recovery is very remote and unlikely.”
    Dias v. City & Cty. of Denver, 
    567 F.3d 1169
    , 1178 (10th Cir. 2009) (quotation
    marks and citations omitted)). So we conclude—given the low threshold for
    amendment and low bar for surviving a motion to dismiss—the plaintiffs alleged
    enough to explore their Monell claim in the discovery process. See 
    id.
     (observing
    that “granting a motion to dismiss is a harsh remedy which must be cautiously
    studied, not only to effectuate the spirit of the liberal rules of pleading but also to
    protect the interests of justice” (quotation marks, alterations, and citation
    omitted)). We thus vacate the district court’s denial of leave to amend and
    remand for further proceedings consistent with this Order.
    III. Conclusion
    In sum, we conclude the complaint does not plausibly allege that Nurse
    Robinson, Officer Valdo, Officer Lopez, Officer Garcia, and Corporal Gallegos
    each violated Ortiz’s clearly established constitutional right to medical care for
    acute symptoms related to his withdrawal from heroin addiction. It does,
    however, plausibly allege a claim against Officer Chavez, so we vacate the
    dismissal with regard to him. We further conclude the district court abused its
    -22-
    discretion in denying the plaintiffs leave to amend because they could plausibly
    state a claim for Monell liability. Our case law permits a plaintiff to bring a
    Monell claim even where there is no individual liability, and the plaintiffs’
    allegations satisfy pleading requirements.
    -23-
    No. 19-2039, Quintana, et al. v. Santa Fe County Board of Commissioners,
    et al.
    BACHARACH, J., concurring in part and dissenting in part.
    Mr. Ricardo Ortiz was arrested for stealing a handbag and booked
    into Santa Fe County’s detention facility. When he was booked, Mr. Ortiz
    had a heroin addiction and expected to experience severe withdrawal. And
    he did. As Mr. Ortiz’s withdrawal spiraled, officials allegedly failed to
    provide treatment. He died three days later.
    On behalf of Mr. Ortiz’s estate, the plaintiffs sued six employees of
    the detention facility, invoking 
    42 U.S.C. § 1983
     1 and alleging that the
    employees had violated the Fourteenth Amendment’s Due Process Clause
    by exhibiting deliberate indifference to Mr. Ortiz’s serious medical needs.
    After an initial amendment, the plaintiffs moved to amend the complaint a
    second time, adding allegations against the employees and a § 1983 claim
    against Santa Fe County.
    In this appeal, we must credit the allegations in the proposed second
    amended complaint and construe all reasonable inferences favorably to the
    plaintiffs. See pp. 6–7, below. After doing so, we must answer two
    questions:
    1.     Would these allegations state a valid claim against the six
    employees for denial of Mr. Ortiz’s constitutional right to
    medical care?
    1
    The plaintiffs also asserted a state-law claim against Santa Fe
    County, but this claim is not involved in the appeal.
    2.    Would these allegations state a valid § 1983 claim against
    Santa Fe County?
    I would answer “yes” to both questions.
    I.   Mr. Ortiz’s Detention and Death
    Mr. Ortiz entered the detention facility in January 2016, and Nurse
    Anne Robinson conducted a medical intake. During the intake, Mr. Ortiz
    looked ill (according to another inmate) and told Nurse Robinson that he
    would soon go into withdrawal. Nurse Robinson arranged for a doctor to
    order medications, but Mr. Ortiz allegedly didn’t receive them.
    During Mr. Ortiz’s first day in the facility, his supervising officer
    was Officer Dylan Chavez. Mr. Ortiz vomited in front of Officer Chavez
    and told him that the vomit was bloody.
    The following morning, Mr. Ortiz met with Officer Anthony Valdo.
    Officer Valdo was responsible for assigning an appropriate housing unit.
    The next day, Officer Tyler Lopez worked in Mr. Ortiz’s housing
    unit. Officer Lopez allegedly saw vomit on the floor and watched Mr. Ortiz
    dry heaving.
    That night, Officer Leonard Garcia came on duty. According to
    another inmate, Mr. Ortiz groaned throughout the night.
    Officer Garcia and Corporal Cristobal Gallegos contend that they
    checked on Mr. Ortiz the next morning and saw that he was not in distress.
    For example, Corporal Gallegos states that he was not alarmed after
    2
    passing Mr. Ortiz’s cell and hearing him pushing and making noises on the
    toilet. And Officer Garcia asserts that he saw Mr. Ortiz minutes later.
    Within 26 minutes of this alleged interaction with Officer Garcia,
    Mr. Ortiz died. His corpse was found in a cell covered with blood and
    feces.
    II.      The District Court’s Rulings
    The six employees sought dismissal of the first amended complaint
    for failure to state a valid claim, urging qualified immunity based on a lack
    of factual allegations reflecting the violation of a clearly established
    constitutional right. The plaintiffs objected to dismissal and requested
    leave to file a second amended complaint. The amendment would have
    supplemented the allegations against the six employees and added a § 1983
    claim against the county for an unconstitutional custom and failure to train
    staff.
    The district court granted the defendants’ motion to dismiss and
    denied the motion for leave to amend on the ground that amendment would
    have been futile. In disallowing the amendment, the court acknowledged
    that the changes would not have prejudiced the defendants. The plaintiffs
    appeal the district court’s dismissal and denial of leave to file a second
    amended complaint.
    3
    III.   The Denial of Leave to Amend the Allegations Against the Six
    Employees Based on Futility
    In my view, the proposed second amended complaint sets forth a
    valid constitutional claim against each of the six employees. I would thus
    reverse the dismissal and the denial of leave to file the second amended
    complaint.
    A.     The Relevance of the Second Amended Complaint
    As a threshold issue, we must consider whether to examine the first
    amended complaint or the second amended complaint. I would consider the
    allegations in the second amended complaint.
    The district court concluded that the proposed second amended
    complaint was “not the product of the Plaintiffs’ desire to cure
    deficiencies.” Appellants’ App’x, vol. 2 at 376. The majority also declines
    to consider the second amended complaint, reasoning that “the plaintiffs
    themselves explicitly denied that the [second amended complaint] would in
    any way cure deficiencies.” Majority Op. at 7. But the plaintiffs didn’t idly
    propose the amendments; instead, the plaintiffs proposed these
    amendments to cure any perceived shortcomings in the first amended
    complaint.
    As the majority points out, the plaintiffs did argue that the added
    details had already been encompassed in the first amended complaint. But
    the plaintiffs recognized that the employees had argued that gaps existed in
    4
    the allegations. So the plaintiffs said that they had rewritten the allegations
    to “summarize” or “better clarify” their allegations. Appellants’ App’x,
    vol. 1 at 131. The plaintiffs also stressed that these clarifications were
    designed to strengthen their claims against the six employees. For example,
    the plaintiffs argued to the district court that
         “[t]he proposed Second Amended Complaint . . . attempts to
    resolve Defendants’ various issues with the operative
    [complaint]” and
         “Plaintiffs have taken Defendants’ issues with the operative
    Complaint seriously, and the proposed Second Amended
    Complaint . . . attempt[s] to clarify allegations that Defendants
    have either asserted they find obscure, or that Defendants
    purport to have interpreted differently than Plaintiffs
    intended.”
    Id. at 128–29 (footnotes omitted). On appeal, the plaintiffs similarly
    maintain that the second amended complaint “enhanced” the claims against
    the individual defendants by making “more explicit” and “emphasiz[ing]”
    allegations encompassed in the first amended complaint. Appellants’
    Opening Br. at 19–21.
    Given the plaintiffs’ explanation for the additional allegations, the
    six employees haven’t questioned the need to consider the second amended
    complaint. The employees instead try to rebut the substance of the second
    amended complaint. See Appellees’ Resp. Br. at 38 (responding to
    allegations in the second amended complaint). Yet the majority insists—
    sua sponte—that we should completely disregard the proposed
    5
    amendment’s additional allegations against the six employees. I would
    instead follow the lead of the six employees and consider those allegations.
    B.    The Standard of Review
    We review the denial of leave to amend a complaint for an abuse of
    discretion. Cohen v. Longshore, 
    621 F.3d 1311
    , 1313 (10th Cir. 2010).
    Though district courts enjoy discretion, they must “freely give leave [to
    amend a complaint] when justice so requires.” Fed. R. Civ. P. 15(a)(2).
    Leave should be granted when an amendment would “yield a meritorious
    claim.” Curley v. Perry, 
    246 F.3d 1278
    , 1284 (10th Cir. 2001). When the
    denial was based on futility, we conduct “de novo review of the legal basis
    for the finding of futility.” Miller ex rel. S.M. v. Bd. of Educ. of
    Albuquerque Pub. Schs., 
    565 F.3d 1232
    , 1249 (10th Cir. 2009).
    In conducting de novo review, we consider why the district court
    regarded amendment as futile. The court reasoned that the second amended
    complaint would not survive a motion to dismiss for failure to state a valid
    claim. Dismissal for failure to state a valid claim would have been proper
    only if the second amended complaint had lacked “enough facts to state a
    claim to relief that [had been] plausible on its face.” Bell Atlantic Corp. v.
    Twombly, 
    550 U.S. 544
    , 570 (2007).
    As the majority observes, the threshold is “low . . . for amendment
    and . . . for surviving a motion to dismiss.” Majority Op. at 22. For
    example, if the six employees had moved to dismiss the second amended
    6
    complaint, the court would have needed to view all well-pleaded factual
    allegations as true and all reasonable inferences in the light most favorable
    to the plaintiffs. Wyoming v. U.S. Dep’t of Interior, 
    839 F.3d 938
    , 942
    (10th Cir. 2016).
    Viewing the second amended complaint’s allegations in this light, we
    must consider whether the six employees would enjoy qualified immunity.
    When qualified immunity is asserted, the plaintiffs must show that the
    defendants violated a constitutional or statutory right that was clearly
    established. Estate of Booker v. Gomez, 
    745 F.3d 405
    , 411 (10th Cir.
    2014).
    To decide whether the second amended complaint would have
    satisfied this burden, we would consider
         whether the plaintiffs adequately alleged that the six employees
    had violated Mr. Ortiz’s constitutional right to medical care
    and
         whether that constitutional right had been clearly established at
    the time of Mr. Ortiz’s detention.
    C.    The Employees’ Assertion of Qualified Immunity
    I conclude that (1) the second amended complaint adequately alleged
    that the six employees had violated Mr. Ortiz’s constitutional right to
    medical care and (2) the constitutional right had been clearly established.
    7
    1.    Violation of the Constitutional Right to Medical Care
    We must first consider whether the plaintiffs’ allegations in the
    second amended complaint entailed a constitutional violation. Saucier v.
    Katz, 
    533 U.S. 194
    , 201 (2001).
    County employees can incur civil liability under 
    42 U.S.C. § 1983
    for violating pretrial detainees’ constitutional right to medical care. Barrie
    v. Grand Cty., 
    119 F.3d 862
    , 867–68 (10th Cir. 1997). This right is
    violated when county employees act with deliberate indifference to
    detainees’ medical needs. Farmer v. Brennan, 
    511 U.S. 825
    , 834 (1994).
    The test for liability consists of objective and subjective prongs. Sealock v.
    Colorado, 
    218 F.3d 1205
    , 1209 (10th Cir. 2000). 2
    The objective prong is satisfied if the prisoner’s medical need was
    “sufficiently serious.” Mata v. Saiz, 
    427 F.3d 745
    , 751 (10th Cir. 2005)
    (quoting Farmer, 
    511 U.S. at 834
    ). A medical need is sufficiently serious
    if it was “diagnosed by a physician as mandating treatment or . . . [was] so
    obvious that even a lay person would easily recognize the necessity for a
    doctor’s attention.” Sealock v. Colorado, 
    218 F.3d 1205
    , 1209 (10th Cir.
    2000) (quoting Hunt v. Uphoff, 
    199 F.3d 1220
    , 1224 (10th Cir. 1999)).
    2
    The subjective prong has been altered for at least some claims
    involving pretrial detainees. See pp. 36–39, below. But we apply the
    subjective prong as it was clearly established at the time of Mr. Ortiz’s
    detention. See 
    id.
    8
    The subjective prong addresses the defendant’s state of mind. Mata,
    
    427 F.3d at 751
    . Under this prong, we ask whether the defendant
         was aware of a substantial risk of serious harm and
         knowingly disregarded that risk.
    See Martinez v. Garden, 
    430 F.3d 1302
    , 1304–05 (10th Cir. 2005) (aware
    of a “substantial risk of serious harm” (quoting Riddle v. Mondragon, 
    83 F.3d 1197
    , 1204 (10th Cir. 1996))); Martinez v. Beggs, 
    563 F.3d 1082
    ,
    1089 (10th Cir. 2009) (knowingly disregards the risk). A plaintiff may
    prove awareness of a substantial risk through circumstantial evidence that
    the risk was obvious. Farmer v. Brennan, 
    511 U.S. 825
    , 842 (1994).
    The second amended complaint satisfies both prongs of the test for
    deliberate indifference as to each employee.
    a.   Objective Prong
    The parties agree that the plaintiffs have satisfied the objective
    prong. But the parties differ on how they define the medical need. In my
    view, the medical need involved Mr. Ortiz’s frequent and bloody vomiting.
    The defendants assert that the medical need involved a
    gastrointestinal hemorrhage, which ultimately led to Mr. Ortiz’s death. But
    the gastrointestinal hemorrhage followed frequent vomiting, which itself
    could satisfy the objective prong if it was serious enough. See Mata v.
    Saiz, 
    427 F.3d 745
    , 753–54 (10th Cir. 2005) (concluding that chest pain
    9
    was sufficiently serious to satisfy the objective prong independently of a
    subsequent heart attack).
    The second amended complaint alleges that Mr. Ortiz was severely ill
    and frequently vomited (sometimes vomiting blood) throughout his time in
    detention. Appellants’ App’x, vol. 1 at 159, 163–64, 171 (vomiting on
    different days); id. at 160, 168 (vomiting blood); id. at 160, 162 (severe
    illness). From these allegations, the fact finder could reasonably infer a
    serious medical need. See Al-Turki v. Robinson, 
    762 F.3d 1188
    , 1193 (10th
    Cir. 2014) (stating that pain satisfied the objective prong when the inmate
    collapsed, vomited, and suffered severe abdominal pain over a period of
    five hours); accord Scinto v. Stansberry, 
    841 F.3d 219
    , 231–32 (4th Cir.
    2016) (concluding that a reasonable jury could find an objectively serious
    medical need based on allegations involving “extreme pain in [the
    inmate’s] stomach, . . . throwing up vomit and blood [and] becom[ing]
    incontinent”).
    Other courts have concluded that severe withdrawal symptoms can
    constitute an objectively serious harm. The Eleventh Circuit, for example,
    has repeatedly held that “alcohol withdrawal is a serious or urgent medical
    problem that requires immediate medical attention.” Lancaster v. Monroe
    Cty., 
    116 F.3d 1419
    , 1425–26 (11th Cir. 1997), overruled in part on other
    grounds by LeFrere v. Quezada, 
    588 F.3d 1317
    , 1318 (11th Cir. 2009). The
    Second Circuit agrees. See Caiozzo v. Koreman, 
    581 F.3d 63
    , 72 (2d Cir.
    10
    2009) (noting the lack of a dispute that severe withdrawal from alcohol had
    constituted a serious medical condition), overruled in part on other
    grounds by Darnell v. Pineiro, 
    849 F.3d 17
    , 35 (2d Cir. 2017). And the
    Fifth Circuit regards delirium tremens (rapid onset of confusion, shaking,
    and hallucinations attributable to withdrawal from alcohol) as a serious
    medical need. Thompson v. Upshur Cty., 
    245 F.3d 447
    , 457 (5th Cir. 2001).
    Just as withdrawal from alcohol can constitute a serious medical need
    when the symptoms are severe, so too can withdrawal from opiates like
    heroin. See Foelker v Outagamie Cty., 
    394 F.3d 510
    , 511–13 (7th Cir.
    2005) (concluding that delirium and other symptoms of a forced
    withdrawal from methadone created a serious medical need). Indeed, the
    six employees concede that serious withdrawal symptoms could satisfy the
    objective prong. See Oral Arg. at 20:00–:06 (“[I] agree that withdrawal, if
    serious enough, can meet that objective constitutional threshold under the
    first prong.”). I thus conclude that Mr. Ortiz’s frequent and bloody
    vomiting could plausibly satisfy the objective prong.
    The majority assumes, without deciding, that “severe opioid
    withdrawal” could satisfy the objective prong. Majority Op. at 9 (emphasis
    in original). But the majority concludes that frequent vomiting alone
    doesn’t constitute a serious medical need.
    Though the majority discounts the severity of “run-of-the-mill”
    withdrawal, a fact finder could reasonably find a serious medical need
    11
    from frequent vomiting associated with heroin withdrawal. Three medical
    experts explain the early effects of withdrawal from heroin:
    From 6 to 12 hours after stopping heroin . . . , symptoms appear,
    such as craving for the substance, anxiety, irritability,
    depression, yawning, sneezing, lacrimation, rhinorrhoea,
    salivation, sweating, shivering and gooseflesh. The pupils dilate,
    there are muscle cramps, anorexia, diarrhoea and vomiting.
    I.A. Liappas, F.A. Jenner & B. Vicente, Review Article, Withdrawal
    Syndromes, 21 J. Royal Coll. Physicians London 214, 215 (1987). The
    vomiting itself can lead to “severe medical complications like dehydration”
    that could result in death. Thomas R. Kosten & Louis E. Baxter, Effective
    Management of Opioid Withdrawal: A Gateway to Opioid Dependence
    Treatment, 28 Am. J. on Addictions 55, 59, 61 (2019). And the plaintiffs
    allege that Mr. Ortiz’s withdrawal led to his death from irritation and
    tearing of his esophageal lining. Appellants’ App’x, vol. 1 at 171. Given
    the plaintiffs’ allegations, the frequent vomiting would satisfy the
    objective prong.
    The employees present three reasons for us to focus on the
    gastrointestinal hemorrhage rather than the frequent or bloody vomiting:
    1.    In district court, the plaintiffs did not preserve an argument
    that the medical need involved frequent vomiting.
    2.    The plaintiffs do not present any plausible factual allegations
    regarding bloody vomiting.
    3.    The plaintiffs do not allege that any of the employees realized
    the frequency of Mr. Ortiz’s vomiting.
    12
    Appellees’ Resp. Br. at 32–33. Each argument fails.
    First, the plaintiffs adequately preserved their argument that the
    medical need consisted of frequent vomiting. The second amended
    complaint repeatedly refers to the employees’ alleged failure to provide
    treatment when they saw Mr. Ortiz “in the throes of severe illness.”
    Appellants’ App’x, vol. 1 at 158; see id. at 159 (“Mr. Ortiz’ Display of
    Severe Withdrawal Symptoms . . . Goes Unaided and Unmonitored”); id. at
    160 (“Staffers Observe Mr. Ortiz in Severe Heroin Withdrawal, but Fail to
    Monitor or Assist Him”); id. at 177–78 (“multiple Individual Defendants
    observed [Mr. Ortiz] to be severely ill; and failed to perform critical
    follow-up monitoring”).
    The plaintiffs also presented these allegations in the first amended
    complaint. See Appellants’ App’x, vol. 1 at 26–28, 37. Opposing dismissal
    of the first amended complaint, the plaintiffs characterized Mr. Ortiz’s
    symptoms as sufficient to satisfy the objective prong. Id. at 94–95. The
    plaintiffs thus preserved their argument on frequent vomiting by
         focusing in both the first and second amended complaints on
    the symptoms of Mr. Ortiz’s illness and
         relying again on these symptoms when opposing the motion to
    dismiss.
    Second, the plaintiffs adequately allege that Mr. Ortiz suffered
    frequent bouts of vomiting, sometimes with blood. The second amended
    complaint contains seven pertinent allegations:
    13
    1.    “Inmate Ronnie Montano – who was housed with Mr. Ortiz
    during his initial intake on January 4 and who later shared
    a cell in the Alpha Unit with him for ‘approximately one
    day’ afterward – later informed investigators that . . . Mr.
    Ortiz ‘appeared sick and “vomited” numerous times’ all
    over the floor, bed, and toilet.” Id. at 159.
    2.    On January 4, “Mr. Ortiz informed Officer Chavez that he
    was withdrawing from heroin and was ‘throwing up
    blood.’” Id. at 160.
    3.    “Mr. Ortiz’ heroin withdrawal symptoms steadily
    worsened throughout the next two days of his confinement
    . . . .” Id.
    4.    On January 6, “[Mr. Ortiz’s] cellmate, Ronnie Montano,
    told Officer Lopez that Mr. Ortiz was sick and had vomited
    in the cell . . . .” Id. at 163.
    5.    “Officer Lopez . . . personally observed Mr. Ortiz ‘dry
    heaving’ in his cell in the Alpha Unit at an unspecified
    time on January 6, 2016, and also saw vomit on the floor.”
    Id.
    6.    “According to Officer Lopez, Mr. Ortiz was ‘very quiet,’
    when not excessively vomiting” on January 6. Id.
    7.    “Significant vomiting from heroin withdrawal caused
    irritation and tearing of Mr. Ortiz’ esophageal lining that
    resulted in ‘bleeding into the stomach and intestines,’
    which resulted in his death.” Id. at 171.
    These allegations indicate that Mr. Ortiz was frequently vomiting,
    sometimes with blood.
    Third, the extent of the employees’ knowledge relates to the
    subjective prong of deliberate indifference, not the objective prong. The
    objective prong considers only whether the alleged injury “is sufficiently
    serious,” not whether the defendants knew about the injury. Mata v. Saiz,
    14
    
    427 F.3d 745
    , 753 (10th Cir. 2005). So the second amended complaint
    adequately alleges a severe medical need involving frequent and bloody
    vomiting.
    b.    Subjective Prong
    The resulting issue is whether the second amended complaint
    satisfies the subjective prong.
    If we credit the allegations in the second amended complaint, Mr.
    Ortiz experienced “serious harm” consisting of frequent, bloody vomiting
    and other severe symptoms of withdrawal. 3 See pp. 9–15, above. Given the
    plaintiffs’ burden at the pleading stage, they must plausibly allege that a
    substantial risk of serious harm was obvious to a reasonable person in each
    employee’s position.
    If we credit the allegations in the second amended complaint and
    draw all reasonable inferences in favor of the plaintiffs, each employee
    3
    The majority concedes that “a jury could conclude the seriousness of
    the medical risks associated with vomiting blood would be obvious to any
    reasonable observer.” Majority Op. at 11. But because frequent vomiting is
    itself a serious harm, see p. 9, above, the proper subjective inquiry is
    whether
         each employee had actual knowledge of Mr. Ortiz’s frequent or
    bloody vomiting or
         a substantial risk of frequent or bloody vomiting would have
    been obvious to a reasonable person in the defendant’s shoes.
    See p. 9, above.
    15
    would have been aware of a substantial risk of serious harm and knowingly
    disregarded that risk.
    i.    Nurse Robinson
    The first employee to see Mr. Ortiz was Nurse Robinson, who
    conducted the intake. During the intake, Nurse Robinson allegedly failed to
    complete many of the required procedures and to make various
    assessments. The allegations against Nurse Robinson in the second
    amended complaint satisfy the subjective prong.
    (a)   Awareness of a Substantial Risk of Serious Harm
    These allegations suffice in part because they showed Nurse
    Robinson’s awareness of a substantial risk of serious harm. While
    conducting the intake, Nurse Robinson allegedly
         had access to records showing a prior diagnosis of Hepatitis C
    and
         learned that Mr. Ortiz was a heroin user.
    And Mr. Ortiz allegedly informed Nurse Robinson that he would undergo
    withdrawal. Indeed, Nurse Robinson concedes that she expected Mr. Ortiz
    to suffer withdrawal symptoms.
    Aware of Mr. Ortiz’s impending withdrawal, Nurse Robinson would
    have presumably understood the obvious risk that Mr. Ortiz could suffer
    serious symptoms. Indeed, the protocols existed because of this risk. Given
    these protocols and Nurse Robinson’s awareness of the impending
    16
    withdrawal, one could reasonably infer that she was aware of an obvious
    risk to Mr. Ortiz. See Mata v. Saiz, 
    427 F.3d 745
    , 757 (10th Cir. 2005)
    (stating that internal protocols supply circumstantial evidence that a
    prison’s “health care gatekeeper knew of a substantial risk of serious
    harm”); see also Estate of Miller ex rel. Bertram v. Tobiasz, 
    680 F.3d 984
    ,
    990 (7th Cir. 2012) (concluding that “[i]f the circumstances suggest that
    the defendant–official being sued had been exposed to information
    concerning the risk and thus ‘must have known’ about it, then such
    evidence could be sufficient” to show actual knowledge (quoting Sanville
    v. McCaughtry, 
    266 F.3d 724
    , 737 (7th Cir. 2001))). And if Nurse
    Robinson would have been aware of the obvious risk, one could reasonably
    infer that she would have recognized the potential for serious harm.
    Sanville, 
    266 F.3d at 737
    .
    The defendants argue that Mr. Ortiz did not display withdrawal
    symptoms during the intake. But this assertion entails a factual dispute.
    The plaintiffs allege that another inmate saw Mr. Ortiz looking sick during
    his intake, Mr. Ortiz said that he would experience withdrawal, and Nurse
    Robinson knew that Mr. Ortiz suffered from Hepatitis C. Given these
    allegations, Nurse Robinson would have plausibly recognized a substantial
    risk of serious harm.
    The majority questions the obviousness of the risk from Nurse
    Robinson’s knowledge of an impending withdrawal. But the second
    17
    amended complaint also alleges that Mr. Ortiz’s medical needs would have
    been obvious to Nurse Robinson based on her awareness of Mr. Ortiz’s
    impending withdrawal and his affliction with Hepatitis C. For example, the
    plaintiffs allege that a national expert had stated that a licensed medical
    professional like Nurse Robinson “would understand that not referring an
    inmate suffering from heroin withdrawal – especially one with a serious,
    chronic condition like Hepatitis C – to the medical unit would be to expose
    the inmate to the substantial risk of serious harm, including the risk of
    death.” Appellants’ App’x, vol. 1 at 157. Together, the allegations in the
    second amended complaint adequately show Nurse Robinson’s awareness
    of a substantial risk of serious harm.
    (b)   Knowing Disregard of a Risk of Serious Harm to Mr. Ortiz
    The second amended complaint also contains allegations showing
    that Nurse Robinson knowingly disregarded the risk to Mr. Ortiz. Martinez
    v. Beggs, 
    563 F.3d 1082
    , 1089 (10th Cir. 2009).
    The second amended complaint alleges that
         Nurse Robinson conducted a deficient intake and failed to
    implement a withdrawal protocol and
         the protocol required monitoring and reassessment.
    Nurse Robinson downplays these allegations as criticism of her paperwork.
    But the plaintiffs allege that Nurse Robinson failed to complete any of the
    18
    required intake procedures even though she had expected Mr. Ortiz to
    experience severe withdrawal and knew that he suffered from Hepatitis C.
    Nurse Robinson also denies deliberate indifference by arguing that
    she arranged for a doctor to order medication. But the plaintiffs allege that
    Nurse Robinson failed to take any steps to administer the medication 4 or to
    implement a protocol for withdrawal.
    In the majority’s view, the plaintiffs don’t allege that Nurse
    Robinson was responsible for the failure to administer the medication. But
    the majority is mistaken. The plaintiffs allege that Nurse Robinson gave a
    false account about the medication. According to the plaintiffs, Nurse
    Robinson said that Mr. Ortiz had taken the medication, see Appellants’
    App’x, vol. 1 at 158, even though Officer Chavez had told investigators
    that Mr. Ortiz refused to take any of the medication. 
    Id.
    Apart from this inconsistency, the plaintiffs allege that Nurse
    Robinson failed to devise a treatment plan, which would have ensured that
    Mr. Ortiz received the required medication. Id. at 155. We can reasonably
    4
    Nurse Robinson relies on her statement that Mr. Ortiz received his
    first dose of medication and assumes that Mr. Ortiz declined to take the
    subsequent doses. But the plaintiffs allege that Mr. Ortiz did not receive
    any of the medication, citing inconsistencies between the employees’
    statements and security videos. Because we view these allegations in the
    light most favorable to the plaintiffs, see pp. 6–7, above, we may
    reasonably infer that Mr. Ortiz did not receive any of the medication.
    19
    infer that the creation of a treatment plan would have ensured availability
    of Mr. Ortiz’s medication.
    In the second amended complaint, the plaintiffs adequately allege
    that Nurse Robinson’s actions directly resulted in the failure to provide
    Mr. Ortiz with medication or any other treatment. Given these allegations,
    Nurse Robinson could incur liability even if she had arranged for a doctor
    to order medication. See Estate of Miller ex rel. Bertram v. Tobiasz, 
    680 F.3d 984
    , 990 (7th Cir. 2012) (holding that a nurse acted with deliberate
    indifference even though she referred an inmate to another medical unit
    and noted that the inmate should be taking psychiatric medication).
    * * *
    In my view, the second amended complaint adequately alleges a
    constitutional violation by Nurse Robinson.
    ii.   Officer Chavez
    On Mr. Ortiz’s first day in detention, his supervising officer was
    Officer Chavez. The allegations against Officer Chavez satisfy the
    subjective prong.
    (a)   Awareness of a Substantial Risk of Serious Harm
    The allegations suffice in part because they show Officer Chavez’s
    awareness of a substantial risk of serious harm. The second amended
    complaint alleges that Officer Chavez
    20
            saw Mr. Ortiz “experiencing symptoms of severe heroin
    withdrawal” and
            was told by Mr. Ortiz that he had vomited blood.
    Appellants’ App’x, vol. 1 at 159–60. Because vomiting blood can
    constitute a serious harm, see pp. 9–15, above, these allegations show
    Officer Chavez’s awareness of a substantial risk of that harm.
    Officer Chavez argues that as a detention officer, he was “entitled to
    defer to the professional medical judgment of medical personnel in the care
    and treatment of detainees.” Appellees’ Resp. Br. at 45–46. But this
    argument requires us to disregard other allegations in the second amended
    complaint. For example, the plaintiffs allege that Mr. Ortiz’s condition
    spiraled downward during his detention. Despite this downward spiral, the
    second amended complaint does not suggest that Officer Chavez consulted
    with medical staff or relied on a medical assessment. And the plaintiffs
    allege that Officer Chavez had been trained to recognize the need for
    immediate emergency medical attention for inmates vomiting blood during
    withdrawal.
    Together, the allegations in the second amended complaint
    adequately allege Officer Chavez’s awareness of a severe medical need.
    21
    (b)   Knowing Disregard of a Risk of Serious Harm to Mr. Ortiz
    The plaintiffs also adequately allege that Officer Chavez knowingly
    disregarded Mr. Ortiz’s medical need.
    In the second amended complaint, the plaintiffs allege that Officer
    Chavez told the next shift about Mr. Ortiz’s condition, but didn’t take any
    other steps to help Mr. Ortiz or refer him to the medical unit. Reporting
    Mr. Ortiz’s condition would not necessarily constitute a reasonable
    measure to avert the harm. See Harper v. Lawrence Cty., 
    592 F.3d 1227
    ,
    1235 (11th Cir. 2010) (holding that the defendant was not entitled to
    summary judgment when he had informed the next shift and another
    official about medical issues but had not taken “any steps to actually
    secure immediate medical attention”), abrogated on other grounds by
    Randall v. Scott, 
    610 F.3d 701
    , 709 (11th Cir. 2010). So the plaintiffs
    adequately allege that Officer Chavez knowingly disregarded a risk of
    serious harm.
    * * *
    In my view, the second amended complaint adequately alleges a
    constitutional violation by Officer Chavez. 5
    5
    The majority concludes that the first amended complaint stated a
    valid claim against Officer Chavez. I agree. But the majority has
    disregarded the plaintiffs’ effort to supplement their allegations against
    Officer Chavez.
    22
    iii.   Officer Valdo
    Roughly one day after arriving at the detention unit, Mr. Ortiz met
    with Officer Valdo, who was responsible for selecting the appropriate
    housing unit. In the second amended complaint, the plaintiffs adequately
    allege that Officer Valdo violated the subjective prong.
    (a)    Awareness of a Substantial Risk of Serious Harm
    The plaintiffs allege that during the interaction with Officer Valdo,
    Mr. Ortiz had a “severely ill appearance” and requested housing in “safe
    keeping.” Appellants’ App’x, vol. 1 at 161. The second amended complaint
    also alleges that Officer Valdo
        was aware of Mr. Ortiz’s diagnosis of Hepatitis C and
        knew from experience and Mr. Ortiz’s ill appearance that he
    needed immediate medical assistance to prevent “an excessive
    risk of serious harm.”
    
    Id.
    The plaintiffs further allege that Officer Chavez had informed later
    shifts of Mr. Ortiz’s condition. We must view these allegations and
    reasonable inferences favorably to the plaintiffs. See pp. 6–7, above. Doing
    In my view, the district court erred in disallowing additional
    allegations even though the existing allegations had stated a valid claim
    against Officer Chavez. The district court disallowed additional allegations
    on the ground that amendment would have been futile. Given our
    unanimous conclusion that the existing allegations sufficed for a valid
    claim against Officer Chavez, the additional allegations would obviously
    not have been futile.
    23
    so, we can reasonably infer that Officer Chavez’s report had reached
    Officer Valdo. See Bistline v. Parker, 
    918 F.3d 849
    , 888 n.20 (10th Cir.
    2019) (applying the plausibility standard and making a “reasonable
    assumption” based on facts from a complaint); see also Sepúlveda-Villarini
    v. Dep’t of Educ., 
    628 F.3d 25
    , 30 (1st Cir. 2010) (“A plausible but
    inconclusive inference from pleaded facts will survive a motion to dismiss
    . . . .”).
    Together, the allegations in the second amended complaint plausibly
    establish that Officer Valdo recognized a substantial risk of serious harm.
    (b)      Knowing Disregard of a Risk of Serious Harm to Mr. Ortiz
    The plaintiffs also adequately allege that Officer Valdo knowingly
    disregarded this risk. The second amended complaint alleges that Officer
    Valdo failed to authorize medical treatment for Mr. Ortiz despite
    knowledge of his medical distress. The plaintiffs thus adequately allege
    that Officer Valdo knowingly disregarded a risk of serious harm to Mr.
    Ortiz.
    * * *
    In my view, the second amended complaint adequately alleges a
    constitutional violation by Officer Valdo.
    24
    iv.   Officer Lopez
    On Mr. Ortiz’s third day in detention, Officer Lopez was on duty.
    The plaintiffs have adequately alleged that Officer Lopez satisfied the
    subjective prong.
    (a)   Awareness of a Substantial Risk of Serious Harm
    The plaintiffs adequately allege that Officer Lopez was aware of a
    substantial risk of serious harm. Officer Lopez allegedly
         knew that Mr. Ortiz was withdrawing from heroin,
         knew that Mr. Ortiz was ill and vomiting in his cell,
         observed vomit on the floor,
         saw Mr. Ortiz “dry heaving,”
         saw Mr. Ortiz “look[] sick,” quietly staring with a blank look,
         recognized the progression of Mr. Ortiz’s symptoms to the
    point that he had become severely ill, and
         could recognize the need for immediate medical attention for
    inmates experiencing illness and vomiting from opiate
    withdrawal.
    These allegations showed that the risk of serious harm was obvious
    to Officer Lopez, suggesting his awareness of the risk. See Scinto v.
    Stansberry, 
    841 F.3d 219
    , 232 (4th Cir. 2016) (“Plaintiff’s testimony that
    his cell ‘reeked’ and his face exhibited visible signs of illness, as well as
    his contemporaneous account of his symptoms create a genuine factual
    dispute about whether his need for medical attention was so obvious that
    25
    an official observing the scene would have . . . inferred that such a
    substantial risk was present.”).
    Officer Lopez argues that frequent vomiting may be a “common”
    characteristic of withdrawal. But a medical need may be severe even when
    it is common. Heart attacks may be common, but they are undoubtedly
    serious.
    The majority contends that the plaintiffs don’t allege that Officer
    Lopez knew about Mr. Ortiz’s condition. But the allegations in the second
    complaint could reasonably entail awareness of Mr. Ortiz’s condition. For
    example, we can reasonably infer that Officer Chavez’s report of Mr.
    Ortiz’s serious condition reached Officer Lopez. And the plaintiffs allege
    that Officer Lopez observed Mr. Ortiz’s distress. Together, these
    allegations indicate that Officer Lopez was aware of an obvious risk to Mr.
    Ortiz.
    In arguing to the contrary, the majority cites Martinez v. Beggs, 
    563 F.3d 1082
     (10th Cir. 2009). But Martinez involved different circumstances
    and a different burden of proof. There Mr. Ginn was arrested for public
    intoxication and died of a heart attack while in custody. Martinez, 
    563 F.3d at 1084
    . But the court held that the risk of a heart attack had not been
    obvious because Mr. Ginn lacked symptoms suggesting an imminent heart
    attack. 
    Id. at 1091
    . The Court explained that “there was no evidence that
    [Mr.] Ginn was in pain or distress.” 
    Id. at 1090
    .
    26
    Our facts are different. The plaintiffs allege that Mr. Ortiz was
    frequently vomiting, sometimes with blood, over the course of three days.
    Indeed, the majority concedes that the fact finder could reasonably infer
    that Mr. Ortiz’s distress was obvious and required medical attention. And
    the plaintiffs allege that Officer Lopez knew that Mr. Ortiz was ill. In
    Martinez, the record contained no evidence that the defendant had known
    of the inmate’s pain or distress. 
    Id.
    Our case differs not only factually but also procedurally. Martinez
    addressed an award of summary judgment, 
    id. at 1084
    ; and we are at the
    motion-to-dismiss stage, addressing only the adequacy of the plaintiffs’
    allegations about Officer Lopez’s awareness of Mr. Ortiz’s condition. See
    Barton v. Taber, 
    820 F.3d 958
    , 967 (8th Cir. 2016) (stating that the
    plausibility standard “is a highly deferential standard, as opposed to that at
    the summary judgment stage”); Davis v. Howard, 
    561 F.2d 565
    , 570 (5th
    Cir. 1977) (distinguishing cases because they had originated on motions
    for summary judgment rather than motions under Rule 12(b)(6)).
    Given these factual and procedural differences, Martinez does not
    suggest futility of the second amended complaint. If we credit the
    allegations in the second amended complaint, Officer Lopez would have
    recognized a substantial risk of serious harm to Mr. Ortiz.
    27
    (b)   Knowing Disregard of a Risk of Serious Harm to Mr. Ortiz
    In the second amended complaint, the plaintiffs also allege facts
    showing that Officer Lopez knowingly disregarded this risk. Despite
    recognizing Mr. Ortiz’s need for medical attention, Officer Lopez
    allegedly failed to obtain any medical help or to do anything to treat Mr.
    Ortiz’s symptoms. The plaintiffs thus adequately allege that Officer Lopez
    knowingly disregarded a risk of serious harm to Mr. Ortiz.
    * * *
    In my view, the second amended complaint adequately alleges a
    constitutional violation by Officer Lopez.
    v.    Officer Garcia
    Two days after arriving at the detention facility, Mr. Ortiz interacted
    with Officer Garcia. The second amended complaint shows Officer
    Garcia’s awareness of a substantial risk of serious harm and knowing
    disregard of that risk.
    (a)   Awareness of a Substantial Risk of Serious Harm
    The plaintiffs allege that (1) another inmate heard Mr. Ortiz
    experiencing violent illness throughout the night, (2) Officer Chavez
    reported Mr. Ortiz’s condition to the next shift, (3) Officer Garcia saw Mr.
    Ortiz sitting on the toilet, breathing hard, “lying on his bed in the fetal
    position,” and “in the throes of severe illness,” and (4) Officer Garcia saw
    28
    Mr. Ortiz “vomiting and defecating blood[] at 8:20 a.m.” Appellants’
    App’x, vol. 1 at 165, 167–68.
    According to the second amended complaint, Officer Garcia
    maintains that he had asked Mr. Ortiz if he was okay and Mr. Ortiz
    responded with a hand gesture, which Officer Garcia interpreted as a
    “yes.” But the plaintiffs allege that motion-activated security videos show
    no sign of an officer approaching Mr. Ortiz’s cell when Officer Garcia says
    that the two men interacted.
    Soon after the last alleged interaction, Officer Garcia allegedly found
    Mr. Ortiz “lying naked across his bed, ‘with his body half off,’” with
    brownish “fluid all over the floor and walls of the cell.” Id. at 166. His
    boxer shorts were oozing blood and feces, with “blood trails . . . on his
    face, coming out of his mouth, his upper arms and shoulders, his rear end,
    and his lower legs and feet.” Id. at 169.
    Officer Garcia stresses that the plaintiffs do not allege that Mr. Ortiz
    requested medical care. But the alleged events would have alerted Officer
    Garcia to Mr. Ortiz’s distress even without a request for medical help. See
    p. 43, below (discussing a similar argument relating to the lack of an
    allegation that Mr. Ortiz had requested medical help). And the plaintiffs
    allege that Officer Garcia obtained training to recognize the need for
    immediate medical assistance for inmates withdrawing from heroin. Given
    this training, a fact finder could reasonably infer that Officer Garcia would
    29
    have recognized a serious medical need even if Mr. Ortiz had not requested
    treatment.
    In the second amended complaint, the plaintiffs point out that Officer
    Garcia denied awareness of Mr. Ortiz’s distress, stating that (1) he had
    checked on Mr. Ortiz three times and (2) Mr. Ortiz had “never presented
    any sign of discomfort or distress.” Appellants’ App’x, vol. 1 at 165. But
    Officer Garcia’s statements conflict with other allegations in the second
    amended complaint, which refer to sounds of Mr. Ortiz’s violent illness
    throughout the night. See Taylor v. Hughes, 
    920 F.3d 729
    , 733 (11th Cir.
    2019) (reversing summary judgment for officials when the guards claimed
    that the detainee had “seemed fine,” but other detainees had heard
    moaning, cries of pain, and pleas for medical help).
    Even if Officer Garcia had checked on Mr. Ortiz, he died within 25
    minutes of the alleged interaction in a cell engulfed in blood and feces,
    suggesting that his death was neither quick nor quiet. The extreme disarray
    in the cell suggests that Mr. Ortiz’s medical distress would have been
    obvious to Officer Garcia. And if the medical distress had been obvious,
    Officer Garcia presumably would have recognized a substantial risk of
    serious harm.
    In the majority’s view, the plaintiffs have not alleged in the first
    amended complaint that Officer Garcia saw Mr. Ortiz in distress. But the
    majority has disregarded these allegations in the second amended
    30
    complaint. There, for example, the plaintiffs allege that Officer Garcia
    “observed Mr. Ortiz violently ill in his cell, vomiting and defecating
    blood.” Appellants’ App’x, vol. 1 at 168.
    The majority appears to recognize the significance of this allegation,
    but disregards it based on the plaintiffs’ characterization of their
    additional allegations as clarification. See pp. 4–6, above. The defendants
    had argued that the allegations in the first amended complaint were too
    “vague.” Appellants’ App’x, vol. 1 at 68. But the plaintiffs disagreed with
    the defendants’ narrow reading of the first amended complaint. To
    eliminate any doubt, the plaintiffs expressly alleged in the second amended
    complaint that Officer Garcia had seen Mr. Ortiz “vomiting and defecating
    blood.” 
    Id. at 168
    .
    The majority elsewhere acknowledges the significance of an
    allegation that one of the officers had seen blood in the vomit:
    The presence of blood in vomit makes the presence of a serious
    medical need more plausible and more obvious. In [the
    majority’s] view, taking the allegations as true, a jury could
    conclude the seriousness of the medical risks associated with
    vomiting blood would be obvious to any reasonable observer.
    Majority Op. at 11.
    Though the majority recognizes that seeing blood in the vomit would
    render Mr. Ortiz’s distress “obvious to any reasonable observer,” the
    majority disregards this allegation because the plaintiffs called their
    changes “clarifying.” We should not disregard admittedly critical
    31
    allegations based on a distorted interpretation of the plaintiffs’
    characterization of their changes—particularly when the majority
    recognizes that the additional allegation regarding the observation of
    bloody vomit would satisfy the subjective prong.
    The fact finder could rely not only on the bloody vomit but also on
    the inconsistencies between the security footage, Officer Garcia’s account,
    and Mr. Ortiz’s obvious distress in the minutes before he died. See Gaston
    v. Coughlin, 
    249 F.3d 156
    , 166 (2d Cir. 2001) (concluding that an inmate’s
    statement that officers had actual knowledge of inhumane conditions
    created a factual dispute for summary judgment because the statement had
    been “premised on the assertion that those men ‘made daily rounds’ of [the
    unit]”); see also Grajales v. Puerto Rico Ports Authority, 
    682 F.3d 40
    , 47
    (1st Cir. 2012) (“[F]or pleading purposes, knowledge is inferable from
    other allegations.”).
    In my view, the plaintiffs’ allegations in the second amended
    complaint support a reasonable inference that Officer Garcia was aware of
    a substantial risk of serious harm.
    (b)   Knowing Disregard of a Risk of Serious Harm to Mr. Ortiz
    The plaintiffs also adequately allege that Officer Garcia knowingly
    disregarded a risk of serious harm. In the second amended complaint, the
    plaintiffs allege that Officer Garcia did nothing to avert the harm. This
    32
    alleged inaction could constitute knowing disregard of a risk of serious
    harm to Mr. Ortiz.
    * * *
    In my view, the second amended complaint adequately alleges a
    constitutional violation by Officer Garcia.
    vi.   Corporal Gallegos
    Corporal Gallegos passed Mr. Ortiz’s cell three days after his arrival
    at the detention facility. The allegations against Corporal Gallegos in the
    second amended complaint suffice under the subjective prong.
    (a)   Awareness of a Substantial Risk of Serious Harm
    These allegations suggest Corporal Gallegos’s awareness of a
    substantial risk of serious harm. According to the second amended
    complaint, Corporal Gallegos heard Mr. Ortiz “pushing” and “making
    noises on the toilet.” Appellants’ App’x, vol. 1 at 166. The plaintiffs also
    allege that Mr. Ortiz’s symptoms had advanced to the point that he “was
    audibly, seriously ill” while Corporal Gallegos was on duty. 
    Id.
     If these
    allegations are credited, the sounds presumably would have alerted
    Corporal Gallegos to Mr. Ortiz’s distress. Corporal Gallegos didn’t just see
    and hear the signs of distress; he also presumably received Officer
    Chavez’s report on Mr. Ortiz’s medical distress. See pp. 23–24, above.
    The plaintiffs also allege that Mr. Ortiz died within 37 minutes after
    Corporal Gallegos had passed the cell. When Mr. Ortiz’s corpse was found,
    33
    his cell was covered with feces, vomit, and blood. Given these allegations,
    a fact finder could reasonably infer that the risk would have been obvious
    to Corporal Gallegos when he saw Mr. Ortiz minutes before his death in a
    cell drenched in feces, vomit, and blood.
    Corporal Gallegos also allegedly knew that Mr. Ortiz was
    experiencing withdrawal from heroin. And Corporal Gallegos allegedly had
    been trained “to recognize the signs of an inmate in need of immediate
    medical attention, a category that includes withdrawing inmates . . . who
    are suffering from symptoms of gastrointestinal illness.” Appellants’
    App’x, vol. 1 at 166–67.
    These allegations plausibly suggest that Corporal Gallegos was aware
    of a substantial risk of serious harm.
    (b)   Knowing Disregard of a Risk of Serious Harm to Mr. Ortiz
    The second amended complaint also alleges that Corporal Gallegos
    failed to obtain any medical assistance for Mr. Ortiz or take any reasonable
    steps to avert the harm. These allegations suggest that Corporal Gallegos
    knowingly disregarded the risk of serious harm to Mr. Ortiz.
    * * *
    In my view, the second amended complaint adequately alleges a
    constitutional violation by Corporal Gallegos.
    34
    2.    The Existence of a Clearly Established Constitutional Right
    I would conclude that the second amended complaint adequately
    alleges a constitutional violation by each of the six employees. So even if
    the first amended complaint had been deficient, these deficiencies would
    have been cured in the second amended complaint. The resulting issue is
    whether that constitutional right was clearly established at the time of Mr.
    Ortiz’s detention. I would answer “yes.”
    a.    Determining the Existence of a Clearly Established Constitutional
    Right
    A right is clearly established when “[t]he contours of the right [were]
    sufficiently clear that a reasonable official would understand that what he
    is doing violates that right.” Gann v. Cline, 
    519 F.3d 1090
    , 1092 (10th Cir.
    2008) (quoting Anderson v. Creighton, 
    483 U.S. 635
    , 640 (1987)). This
    inquiry is designed “to ensure that . . . officers are on notice their conduct
    is unlawful.” Saucier v. Katz, 
    533 U.S. 194
    , 206 (2001).
    Adequate notice to reasonable officials can come from Supreme
    Court precedent, a Tenth Circuit opinion on point, or the weight of
    authority from other circuits. Medina v. City & Cty. of Denver, 
    960 F.2d 1493
    , 1498 (10th Cir. 1992). Precedent must be particularized to the facts
    rather than defined at a “high level of generality.” Apodaca v. Raemisch,
    
    864 F.3d 1071
    , 1076 (10th Cir. 2017). But “general precedents may clearly
    establish the law when the defendant’s conduct ‘obvious[ly]’ violates the
    35
    law.” 
    Id.
     (quoting Brosseau v. Haugen, 
    543 U.S. 194
    , 199 (2004) (per
    curiam)).
    b.    The Clearly Established Law During Mr. Ortiz’s Detention
    We must determine the contours of the constitutional right that was
    clearly established during Mr. Ortiz’s detention. The plaintiffs argue that
    the district court misapplied the subjective prong in light of the Supreme
    Court’s opinion in Kingsley v. Hendrickson, ___ U.S. ___, 
    135 S. Ct. 2466
    (2015). 6 There the Supreme Court held that for excessive-force claims by
    pretrial detainees, the test for deliberate indifference was objective rather
    than subjective. 
    135 S. Ct. at
    2475–76. But Kingsley did not clearly apply
    to pretrial detainees’ claims of inadequate medical care, so the district
    court did not err in applying the subjective prong for purposes of qualified
    immunity.
    Though Kingsley modified the test for deliberate indifference for
    pretrial detainees’ claims of excessive force, the scope of this modification
    did not become clear until after Mr. Ortiz had died. At the time of his
    detention, no circuit court had applied Kingsley outside of the excessive-
    force context.
    6
    The plaintiffs concede the need to show plain error. But the district
    court did not err in applying the subjective prong for purposes of qualified
    immunity, so we need not consider whether an error would have risen to
    the level of “plain error.”
    36
    Absent such case law, the objective test of deliberate indifference
    could have been clearly established only if Kingsley itself had spelled out
    its applicability outside of the excessive-force context. Kingsley, however,
    had not spoken to this question.
    Circuit courts have thus disagreed over its reach. For example, after
    Mr. Ortiz’s detention, some circuits have concluded that Kingsley extends
    beyond excessive-force claims, effectively abrogating the subjective prong
    of deliberate indifference whenever pretrial detainees claim a denial of due
    process. 7 But other circuits have limited Kingsley to excessive-force
    claims. 8 This circuit split suggests that Kingsley did not definitively settle
    the issue.
    7
    The Second, Seventh, and Ninth Circuits have applied Kingsley to
    various claims by pretrial detainees. See Darnell v. Pineiro, 
    849 F.3d 17
    ,
    35–36 (2d Cir. 2017) (applying Kingsley to a claim involving conditions of
    confinement and indicating that the same objective test for deliberate
    indifference applies to all claims involving the Fourteenth Amendment’s
    Due Process Clause); Miranda v. Cty. of Lake, 
    900 F.3d 335
    , 352 (7th Cir.
    2018) (applying Kingsley to all Fourteenth Amendment claims involving
    pretrial detainees); Gordon v. Cty. of Orange, 
    888 F.3d 1118
    , 1124–25 (9th
    Cir. 2018) (stating that Kingsley applies to a pretrial detainee’s claims
    involving deficient medical care).
    8
    The Fifth, Eighth, and Eleventh Circuits have declined to extend
    Kingsley beyond excessive-force claims. See Alderson v. Concordia Par.
    Corr. Facility, 
    848 F.3d 415
    , 419 n.4 (5th Cir. 2017) (declining to apply
    Kingsley because the Fifth Circuit had continued to apply a subjective
    standard post-Kingsley); Whitney v. City of St. Louis, 
    887 F.3d 857
    , 860
    n.4 (8th Cir. 2018) (“Kingsley does not control because it was an excessive
    force case, not a deliberate indifference case.”); Dang ex rel. Dang v.
    Sheriff, Seminole Cty., 
    871 F.3d 1272
    , 1279 n.2 (11th Cir. 2017) (noting
    37
    After Mr. Ortiz’s death, we applied Kingsley outside of the
    excessive-force context in Colbruno v. Kessler, 
    928 F.3d 1155
     (10th Cir.
    2019). Colbruno involved a conditions-of-confinement claim, and we held
    that Kingsley had eliminated the need for a pretrial detainee to show an
    intent to punish. 928 F.3d. at 1163.
    According to the plaintiffs, Colbruno shows that Kingsley abrogated
    the need for pretrial detainees to satisfy a subjective test for deliberate
    indifference. But Colbruno did not address Kingsley in the discussion of a
    clearly established right. See id. at 1163, 1165–66 (examining the
    applicability of Kingsley, but not discussing whether Kingsley had clearly
    established the law prior to the alleged violation). And even after Mr.
    Ortiz’s detention, many Tenth Circuit opinions before Colbruno had
    expressly declined to address Kingsley’s applicability to pretrial detainees
    outside of excessive-force cases. 9
    that Kingsley applied to an excessive-force claim but not to a claim of
    inadequate medical treatment).
    9
    See, e.g., Clark v. Colbert, 
    895 F.3d 1258
    , 1269 (10th Cir. 2018)
    (declining to “revisit the applicable law” because the plaintiff argued only
    that Kingsley had “‘held open the possibility that an objective-only
    standard should apply’ . . . [y]et he [did] not argue that Kingsley actually
    displaced any precedent”); Perry v. Durborow, 
    892 F.3d 1116
    , 1122 n.1
    (10th Cir. 2018) (declining to address the applicability of Kingsley because
    the parties had not briefed the issue and resolution of the issue would not
    affect the outcome of the appeal); Estate of Duke ex rel. Duke v. Gunnson
    Cty. Sheriff’s Office, 752 F. App’x 669, 673 n.1 (10th Cir. 2018)
    (unpublished) (declining to consider the Kingsley issue because both
    parties agreed on the use of the subjective standard); Crocker v. Glanz, 752
    38
    Given the existence of a circuit split and our circuit’s frequent
    avoidance of the issue even after Mr. Ortiz’s detention, we conclude that
    Kingsley itself did not clearly establish a purely objective test for all
    pretrial detainees’ claims of deliberate indifference. So even if Kingsley
    applies to medical-care claims, the six employees would have lacked notice
    of a purely objective test for deliberate indifference. 10 Given the lack of
    notice, the clearly established right in January 2016 included a subjective
    test for deliberate indifference.
    c.    Application to the Employees’ Conduct During Mr. Ortiz’s
    Detention
    The second amended complaint adequately alleges that the six
    employees violated Mr. Ortiz’s clearly established constitutional right to
    medical care. These allegations would defeat qualified immunity if the six
    employees had moved to dismiss the second amended complaint.
    F. App’x 564, 569 (10th Cir. 2018) (unpublished) (declining to consider
    the applicability of Kingsley because it had not been raised in district court
    and would not affect the substantial-rights prong under the plain-error
    test).
    10
    The plaintiffs urge us to clarify the applicability of Kingsley even if
    it does not affect the outcome. But as discussed, Kingsley did not clearly
    apply to medical-care claims at the time of Mr. Ortiz’s detention. I
    wouldn’t expound on an issue that’s immaterial to the outcome.
    39
    i.    Nurse Robinson
    Urging qualified immunity, Nurse Robinson points to a lack of
    precedent stating that intake deficiencies would violate a pretrial
    detainee’s constitutional rights. But a lack of precedent is not fatal here.
    In our circuit, a claim is actionable when the need for medical
    treatment is obvious. The need for treatment is obvious when
    a medical professional completely denies care although
    presented with recognizable symptoms which potentially create
    a medical emergency, e.g., a patient complains of chest pains and
    the prison official, knowing that medical protocol requires
    referral or minimal diagnostic testing to confirm the symptoms,
    sends the inmate back to his cell.
    Self v. Crum, 
    439 F.3d 1227
    , 1232 (10th Cir. 2006) (citing Mata v. Saiz,
    
    427 F.3d 745
    , 755–59 (10th Cir. 2005), and Sealock v. Colorado, 
    218 F.3d 1205
    , 1211–12 (10th Cir. 2000)).
    In the second amended complaint, the plaintiffs adequately allege
    that Nurse Robinson failed to address an obvious need for medical
    treatment. The plaintiffs do not allege just “mistakes in filling out forms,
    making a diagnosis or predicting future possible complications.”
    Appellees’ Resp. Br. at 41. Rather, the plaintiffs allege that Nurse
    Robinson failed to address an obvious need for medical treatment. See pp.
    16–20, above.
    The plaintiffs’ allegations indicate that Nurse Robinson
         knew that Mr. Ortiz was addicted to heroin and had been
    diagnosed with Hepatitis C,
    40
         expected him to suffer withdrawal,
         knew that the medical protocol required intake assessments and
    continued monitoring, and
         failed to take steps to make sure that Mr. Ortiz received any
    treatment.
    Her inaction in the face of an obvious medical risk would inherently
    violate a clearly established constitutional right. See, e.g., Phillips v.
    Roane Cty., 
    534 F.3d 531
    , 545 (6th Cir. 2008) (noting that the law is
    clearly established that “where the circumstances are clearly sufficient to
    indicate the need of medical attention for injury or illness, the denial of
    such aid constitutes the deprivation of constitutional due process” (quoting
    Estate of Carter v. City of Detroit, 
    408 F.3d 305
    , 313 (6th Cir. 2005)));
    Orlowski v. Milwaukee Cty., 
    872 F.3d 417
    , 422 (7th Cir. 2017). For
    example, in Orlowski v. Milwaukee County, the Seventh Circuit stated:
    The violation alleged by [the plaintiffs] is “clearly established”
    if [the two correctional officers] had fair and clear warning that
    their alleged actions (or inaction) would be constitutionally
    offensive. We find that, assuming the facts most favorable to [the
    plaintiffs], they did. Correctional officials have long been
    warned that they cannot ignore an inmate’s known serious
    medical condition. . . . Where a duty imposed by law is obvious
    to a reasonable officer, we consider it “clearly established.” . . .
    Here, the [plaintiffs’ evidence] indicates that [the inmate]
    presented obvious symptoms of a serious medical condition. So,
    if we accept these facts as true, any reasonable officer would
    know he had a duty to seek medical attention. If [the correctional
    officers] chose to do nothing despite this duty, they violated
    “clearly established” Eight [sic] Amendment law.
    872 F.3d at 422 (citations & footnote omitted).
    41
    I agree with the Seventh Circuit’s reasoning. Because a fact finder
    could reasonably infer that Mr. Ortiz had obviously needed medical
    attention, nurses couldn’t reasonably think that the Constitution would
    permit them to do nothing. So if a nurse chose not to respond to an obvious
    medical need, the nurse would have violated a clearly established
    constitutional right. Id.
    According to the plaintiffs, Nurse Robinson simply arranged for
    medications without taking any steps to ensure delivery to Mr. Ortiz or to
    complete the required protocols for inmates facing withdrawal. If we credit
    these allegations, as required, Nurse Robinson’s inaction would have
    violated a clearly established constitutional right.
    ii.   Officer Chavez, Officer Valdo, Officer Lopez, Officer Garcia, and
    Corporal Gallegos
    The other five employees also deny violating a clearly established
    right, pointing to a lack of precedents with analogous facts. But prior to
    Mr. Ortiz’s detention, circuit courts had often characterized similar
    conduct as unconstitutional. See, e.g., Taylor v. Hughes, 
    920 F.3d 729
    , 733
    (11th Cir. 2019) (holding that guards may have violated the constitutional
    rights of a detainee who had “spent several hours moaning, crying out in
    pain, and begging for medical help”); Westlake v. Lucas, 
    537 F.2d 857
    , 859
    (6th Cir. 1976) (holding that a complaint adequately stated a claim under
    Fed. R. Civ. P. 12(b)(6) when jail officials were aware of a prisoner’s
    42
    ulcer, but did not allow a medical examination even after he had begun
    vomiting blood).
    The defendants try to distinguish these opinions, pointing out that
    Mr. Ortiz
         didn’t ask for medical assistance,
         experienced withdrawal, and
         allegedly declined to take withdrawal medication.
    Each argument fails.
    First, Mr. Ortiz’s constitutional right does not turn on whether he
    asked for medical assistance. A request for assistance could affect a fact
    finder’s conclusions on the obviousness of the medical need, but a request
    is not necessary to establish the defendant’s recognition of a medical need.
    See Youmans v. Gagnon, 
    626 F.3d 557
    , 566 n.12 (11th Cir. 2010) (per
    curiam) (“A person is not required to request medical care to prevail on a
    claim of deliberate indifference to a serious medical need.”); see also
    McCaster v. Clausen, 
    684 F.3d 740
    , 748 (8th Cir. 2012) (concluding that
    correctional officers could incur liability for deliberate indifference even
    though the ill prisoner had not personally requested medical help).
    Second, Mr. Ortiz had a constitutional right to treatment for his
    serious medical need even though the need stemmed from heroin
    withdrawal. See Vaughn v. Gray, 
    557 F.3d 904
    , 909 (8th Cir. 2009)
    (concluding that even if the defendants had attributed a prisoner’s
    43
    vomiting to his ingestion of shampoo, the defendants could have
    recognized a need for medical attention). And other courts of appeals have
    concluded that the need for medical attention was obvious in similar
    situations. See Harper v. Lawrence Cty., 
    592 F.3d 1227
    , 1237 (11th Cir.
    2010) (stating that prior cases “should have put any government actor on
    notice that delayed or inadequate treatment of alcohol withdrawal would be
    unlawful”), abrogated on other grounds by Randall v. Scott, 
    610 F.3d 701
    ,
    709 (11th Cir. 2010).
    The majority likewise determines that a clearly established
    constitutional violation is not foreclosed by withdrawal from heroin;
    otherwise, the claim against Officer Chavez would fail. See Majority Op. at
    18. Indeed, the majority assumes (without deciding) that Mr. Ortiz’s severe
    withdrawal from opioids would have constituted a serious medical need.
    Id. at 9.
    Third, the second amended complaint alleges that the detention
    facility’s staff didn’t supply “Mr. Ortiz with the opiate-withdrawal
    medications he [had] paid for.” Appellants’ App’x, vol. 1 at 158. In
    response, the employees argue that Mr. Ortiz declined the medications. But
    the plaintiffs have adequately alleged contradictory accounts from the
    employees, id. at 157–58, and discrepancies between these accounts and
    security footage, id. at 162–63. The court can’t resolve this factual dispute
    44
    when assessing whether the proposed second amended complaint states a
    valid claim. See p. 19 n.4, above.
    The majority asserts that the cases do not offer “the requisite degree
    of specificity,” contending that the cases “address medical conditions other
    than withdrawal from heroin.” Majority Op. at 17. Yet the majority
    concedes that for Officer Chavez, it’s enough to show that Officer Chavez
    had ignored obvious and serious medical needs. Id. at 18. Why isn’t this
    enough for Officer Valdo, Officer Lopez, Officer Garcia, and Corporal
    Gallegos? All of them allegedly knew about the frequent vomiting, and
    Officer Garcia allegedly knew that Mr. Ortiz had blood in his vomit and
    feces.
    The majority argues that only a few circuit cases have recognized a
    constitutional violation in similar circumstances. But the majority
    concedes that a fact finder could reasonably infer an obvious medical need.
    See p. 15 n.3, above. Given this concession, what more did the plaintiffs
    need to allege to defeat qualified immunity? Surely employees in a
    detention unit didn’t need a precedent to tell them that the Constitution
    prohibited them from ignoring an inmate’s frequent and bloody vomiting
    over a three-day period?
    The employees never made such an argument, and it would have been
    remarkable if they had. Any reasonable employee would have realized that
    the Constitution wouldn’t allow conscious disregard of an inmate
    45
    experiencing severe withdrawal symptoms and frequent vomiting
    (sometimes with blood) over the course of three days.
    * * *
    In sum, the plaintiffs adequately allege in the second amended
    complaint that
         Mr. Ortiz suffered an objectively serious medical need
    consisting of frequent vomiting (sometimes with blood) and
         Nurse Robinson, Officer Chavez, Officer Valdo, Officer Lopez,
    Officer Garcia, and Corporal Gallegos knowingly disregarded a
    risk of serious harm to Mr. Ortiz.
    These employees’ alleged disregard of Mr. Ortiz’s medical need would
    have violated a clearly established constitutional right. I would thus
    reverse the district court’s dismissal and the denial of leave to file the
    second amended complaint to supplement the allegations against the six
    employees.
    IV.    The Denial of Leave to Amend by Adding a § 1983 Claim Against
    Santa Fe County
    The plaintiffs also challenge the denial of their motion to amend by
    adding a § 1983 claim against Santa Fe County. The district court denied
    the motion as futile, concluding that the additional claim against the
    county would not survive a motion to dismiss. I disagree, as the majority
    does. 11
    11
    Though I agree with the majority on the outcome as to this issue, our
    reasoning differs.
    46
    A.    The Standard of Review
    As noted above, the district court disallowed amendment solely on
    the ground of futility. So we must apply de novo review. See p. 6, above.
    B.    Municipal Liability
    When engaging in de novo review of a futility determination, we
    consider the claim that the plaintiffs wanted to add. Here the additional
    claim would involve municipal liability under 
    42 U.S.C. § 1983
    . The
    plaintiffs contend that Santa Fe County incurs liability based on a custom
    reflecting deliberate indifference to the serious medical needs of inmates
    experiencing withdrawal. 12
    For this claim, the plaintiffs must allege a plausible basis to infer
         a custom or official policy,
         causation, and
         deliberate indifference.
    Schneider v. City of Grand Junction Police Dep’t., 
    717 F.3d 760
    , 769, 771
    n.5 (10th Cir. 2013). 13
    12
    The plaintiffs also allege that the county failed to adequately train its
    employees to respond to medical needs. Given the adequacy of the
    plaintiffs’ allegation of an unconstitutional custom, we need not address
    the allegation of inadequate training.
    13
    The county also argues that the plaintiffs must allege a constitutional
    violation by at least one individual defendant to trigger municipal liability.
    For the sake of argument, I assume that the county is right. In my view, the
    second amended complaint adequately alleges constitutional violations by
    each of the six employees. See pp. 7–34, above.

    The plaintiffs should have been able to amend the complaint to assert
    a § 1983 claim against Santa Fe County. The second amended complaint
    alleges that
            Santa Fe County maintained an unconstitutional custom of
    failing to treat detainees for alcohol or narcotics withdrawal,
            the county’s custom caused Mr. Ortiz’s injury, and
            the county’s action stemmed from deliberate indifference.
    1.    Santa Fe County’s Alleged Custom
    In the second amended complaint, the plaintiffs allege that (1) the
    county acted with deliberate indifference to “the serious medical needs of
    inmates suffering from alcohol and narcotics withdrawals” and (2) the
    deliberate indifference was “so persistent, continuing, and widespread as to
    constitute a custom.” Appellants’ App’x, vol. 1 at 183.
    Plaintiffs can allege an informal custom through a “longstanding
    practice or custom which constitutes the ‘standard operating procedure’ of
    the local governmental entity.” Jett v. Dall. Indep. Sch. Dist., 
    491 U.S. 701
    , 737 (1989) (quoting Pembaur v. City of Cincinnati, 
    475 U.S. 469
    ,
    485–87 (1986) (White, J., concurring)).
    To allege an unconstitutional custom, the plaintiffs point to three
    pieces of information in the second amended complaint:
    1.       Mr. Ortiz’s history after his prior arrests of “eight inadequate
    withdrawal evaluations and no follow-up monitoring of his
    withdrawal symptoms,”
    48
    2.    the Department of Justice’s 2003 findings that the detention
    facility’s “‘intake medical screening, assessment, and referral
    process’ [had] violated [pretrial] detainees’ constitutional
    rights, including the rights of inmates experiencing
    withdrawals,” and
    3.    the 2015 and 2016 withdrawal-related deaths of three other
    pretrial detainees involving the same facility—Dr. Thomas
    Pederson, Mr. John DeLaura, and Ms. Stacy Lynn Gambler.
    Appellants’ Opening Br. at 52 (quoting Appellants’ App’x, vol. 1 at 183).
    Together, these allegations reflect an unconstitutional custom.
    a.    History of Mr. Ortiz’s Intakes
    The plaintiffs rely in part on Mr. Ortiz’s history of inadequate
    intakes. The county contends that Mr. Ortiz’s history of inadequate intakes
    cannot contribute to liability because the past deficiencies did not cause an
    injury. But the plaintiffs need not allege that every deficient intake
    resulted directly in an injury. Rather, the alleged custom must have been
    “maintained with deliberate indifference to an almost inevitable
    constitutional injury.” Schneider v. City of Grand Junction Police Dep’t.,
    
    717 F.3d 760
    , 769 (10th Cir. 2013) (emphasis added). In my view, the
    plaintiffs’ allegations indicate that the improper intakes created the near
    inevitability of a constitutional injury.
    The county argues that Mr. Ortiz’s history of inadequate intakes does
    not imply a custom because the prior intakes didn’t involve identical
    failings within the intake procedure. But the county urges an unreasonable
    level of specificity. The plaintiffs allege a pattern of inadequate intakes,
    49
    not routine disregard of one particular requirement. See Appellants’ App’x,
    vol. 1 at 148–52 (detailing a lack of monitoring and incomplete, inaccurate
    forms at Mr. Ortiz’s intakes between June 2013 and February 2015). The
    alleged pattern of inadequate intakes could reasonably constitute a custom.
    b.    The DOJ Report
    The plaintiffs also rely on a 2003 DOJ report, which concluded that
    the facility’s intake process had violated the constitutional rights of
    pretrial detainees, including those experiencing withdrawal. The county
    attaches little importance to the report, arguing that (1) it is old and (2) the
    detention facility was operated by a different entity when the violations
    took place. The passage of time and change in operators could diminish the
    persuasive value of the report. But the report could still contribute to the
    existence of a custom involving deficient intakes.
    c.    The Withdrawal-Related Deaths of Other Pretrial Detainees
    The plaintiffs also point to the withdrawal-related deaths of Dr.
    Pederson, Mr. DeLaura, and Ms. Gambler. The county points out that in
    each case, the withdrawal involved alcohol rather than heroin. But a fact
    finder need not disregard the prior incidents just because the withdrawal-
    related deaths had involved a different substance.
    For Dr. Pederson, the plaintiffs allege that the intake nurse didn’t
    “perform a Poly Substance Abuse Assessment ‘that would have indicated
    [a] drinking and complication history and would have helped triage him
    50
    into the medical unit.’” Appellants’ App’x, vol. 1 at 173 (emphasis
    deleted) (quoting an internal investigation conducted after Dr. Pederson’s
    death). That alleged lapse resembles Nurse Robinson’s alleged failure to
    perform a complete assessment for Mr. Ortiz’s heroin withdrawal. See 
    id.
    at 155–56. Given the similarity in the alleged lapses, we can reasonably
    infer that the intake deficiencies contributed to an unconstitutional custom
    even though Dr. Pederson’s substance differed from Mr. Ortiz’s.
    The county also argues that an alleged pattern of conduct based on
    another substance (like alcohol) should require a correspondingly greater
    “number of similar incidents . . . to show a persistent, continuing,
    widespread practice.” Appellees’ Resp. Br. at 65–66. And the plaintiffs do
    not allege any incidents between 2004 and 2015. At this stage, though, the
    plaintiffs need only plausibly allege the existence of a custom, which was
    reflected in these incidents.
    2.    Causation
    The plaintiffs must also allege a direct causal link between the
    custom and the alleged injury. Schneider v. City of Grand Junction Police
    Dep’t., 
    717 F.3d 760
    , 770 (10th Cir. 2013). The plaintiffs satisfy this
    51
    requirement by linking Mr. Ortiz’s injury to the custom of inadequate
    intakes.
    The county argues that the proposed second amended complaint does
    not link the three other deaths to withdrawal or deficient intakes. I
    disagree.
    The proposed second amended complaint adequately alleges that the
    prior deaths stemmed from withdrawal. See Appellants’ App’x, vol. 1 at
    173 (“Dr. Thomas Pederson collapsed and died . . . while suffering from
    severe alcohol withdrawal.”); 
    id. at 174
     (“John DeLaura died of
    complications from severe alcohol withdrawal.”); 
    id. at 175
     (“Stacy Lynn
    Gambler was . . . suffering from . . . severe alcohol withdrawals . . . [and
    subsequently] died.”).
    The second amended complaint also adequately links the deaths to
    the deficiencies in the intakes, for the plaintiffs allege that
         Dr. Pederson suffered because “the intake nurse [had] failed to
    perform critical assessments or sign appropriate forms,” 
    id. at 173
    ,
         officials had denied “proper medical attention” to Mr. DeLaura,
    
    id. at 174
    , and
         officials violated facility policy by improper monitoring and
    treating Ms. Gambler “with only over-the-counter painkillers
    and routine alcohol withdrawal medication, even as her
    condition rapidly deteriorated,” 
    id. at 175
    .
    And the plaintiffs allege that an internal report linked Dr. Pederson’s death
    to deficiencies in his intake. 
    Id. at 173
    .
    52
    * * *
    In combination, the plaintiffs’ allegations satisfy the element of
    causation.
    3.    Deliberate Indifference
    Finally, the plaintiffs must plausibly allege facts showing that the
    municipal action stemmed from “‘deliberate indifference’ as to its known
    or obvious consequences.” Schneider v. City of Grand Junction Police
    Dep’t., 
    717 F.3d 760
    , 770 (10th Cir. 2013) (quoting Bd. of Cty. Comm’rs v.
    Brown, 
    520 U.S. 397
    , 407 (1997)). A municipality is deliberately
    indifferent when it “has actual or constructive notice that its action or
    failure to act is substantially certain to result in a constitutional violation.”
    Barney v. Pulsipher, 
    143 F.3d 1299
    , 1307 (10th Cir. 1998). Notice can
    come from “the existence of a pattern of tortious conduct” or facts showing
    that a constitutional violation is a “‘highly predictable’ or ‘plainly
    obvious’ consequence of a municipality’s action or inaction.” 
    Id.
     at 1307–
    08 (quoting Brown, 
    520 U.S. at 409
    ).
    The second amended complaint alleges that the county had actual or
    constructive notice. For instance, an internal report highlighted intake
    deficiencies, which resulted in constitutional violations. The report also
    identified actions that could prevent additional deaths from withdrawal,
    including better documentation, orientation for medical personnel, and
    improved procedures to designate inmates needing medical attention. This
    53
    internal investigation, which preceded Mr. Ortiz’s death, could have
    alerted the county to a need for corrective action. 14
    The 2003 DOJ report also could have given the county notice that
    intake deficiencies had been commonplace. Although a private company
    ran the facility at the time, the report could still render a constitutional
    violation “highly predictable.” Barney, 
    143 F.3d at 1308
     (quoting Brown,
    
    520 U.S. at 409
    ). We can also reasonably infer an absence of corrective
    action in light of Mr. Ortiz’s death and the alleged deficiencies in his
    intake.
    * * *
    In the second amended complaint, the plaintiffs adequately allege
    deliberate indifference by Santa Fe County. The district court thus erred by
    denying leave to amend by adding a § 1983 claim against the county.
    V.    Conclusion
    In my view, the proposed second amended complaint states a valid
    claim against Nurse Robinson, Officer Chavez, Officer Valdo, Officer
    14
    The county argues that Mr. DeLaura’s death is immaterial because it
    occurred after Mr. Ortiz had died. But this argument misunderstands the
    inquiry. The other incidents need not have caused Mr. Ortiz’s injury.
    Instead, the other incidents must contribute to a custom that caused Mr.
    Ortiz’s injury. Mr. DeLaura’s subsequent death could contribute to the
    inference of an unconstitutional custom, and the preceding deaths and
    reports could help establish notice.
    54
    Lopez, Officer Garcia, and Corporal Gallegos. Based on the plaintiffs’
    allegations, a fact finder could reasonably infer that
         Mr. Ortiz’s serious risk of harm would have been obvious to
    these employees and
         these employees knowingly disregarded that risk.
    Their alleged inaction would have violated Mr. Ortiz’s clearly established
    constitutional right, so I would reverse the dismissal and the denial of
    leave to amend the allegations against the six employees.
    The district court also erred in disallowing an amendment to add a
    § 1983 claim against Santa Fe County.
    I would thus (1) reverse the dismissal and denial of leave to file a
    second amended complaint and (2) remand for further proceedings.
