    Before: HENDERSON, TATEL and MILLETT, Circuit Judges.
    Opinion for the Court filed by Circuit Judge HENDERSON.
    KAREN LECRAFT HENDERSON, Circuit Judge: The
    Constitution limits our “judicial Power” to “Cases” and
    “Controversies,” U.S. CONST. art. III, § 2, cl. 1, and there is no
    justiciable case or controversy unless the plaintiff has standing,
    Steel Co. v. Citizens for a Better Env’t, 
    523 U.S. 83
    , 102
    (1998). To stave off dismissal for lack of standing, the
    plaintiff must sufficiently allege a “concrete and
    particularized” injury that is “fairly traceable to the challenged
    action of the defendant” and “likely” to be “redressed by a
    favorable decision.” Lujan v. Defenders of Wildlife, 
    504 U.S. 555
    , 560-61 (1992) (internal quotations, brackets and ellipses
    omitted). Arthur West, the plaintiff here, does not meet this
    “irreducible constitutional minimum.” 
    Id. at 560.
    West lives in the state of Washington, which since the late
    1990s has permitted the use of marijuana for medical purposes.
    He holds a medical marijuana authorization and uses marijuana
    for an undisclosed medical reason.           He opposes the
    legalization of recreational marijuana, however, which
    Washington approved in 2012 through a ballot initiative. In
    West’s view, the initiative and subsequent amendments are bad
    for the state’s environment and for medical marijuana users
    like him.
    All of Washington’s laws governing marijuana—medical
    and recreational—are in tension with the Controlled
    3
    Substances Act of 1970 (CSA), 21 U.S.C. §§ 801 et seq., which
    makes it a federal crime to manufacture, distribute or possess
    with intent to distribute marijuana. In 2013, the United States
    Department of Justice (Department), through then-Deputy
    Attorney General James Cole, issued a guidance memorandum
    (Cole Memorandum) to federal prosecutors about enforcement
    of the CSA in cases involving marijuana. The memorandum,
    prompted by Washington’s 2012 ballot initiative and a similar
    one in Colorado, advises federal prosecutors generally to rely
    on state authorities to address marijuana activity unless the
    state’s regulatory system is insufficiently robust or the activity
    implicates a federal enforcement priority. West sued the
    Department, Deputy Attorney General Cole and other federal
    and state officials in district court, claiming in a pro se
    complaint that the Cole Memorandum unconstitutionally
    “commandeer[s]” state officials and institutions.1 Pl.’s Am.
    Compl. (Compl.), Dkt. No. 14 at 1. He also claimed that all
    defendants violated the National Environmental Policy Act of
    1969 (NEPA), 42 U.S.C. §§ 4321 et seq., by failing to prepare
    an environmental impact statement before publication of the
    memorandum. He alleged that, taken together, Washington’s
    laws and the memorandum subject him to injuries from the
    wider availability of recreational marijuana and new
    restrictions on medical marijuana. The relief he sought
    centered not on state law but on the memorandum: he asked
    that it be “void[ed]” and that all defendants “be compelled to
    comply with . . . NEPA” in connection with the “federal . . .

    West filed his complaint in the District of Columbia rather
    than the Western District of Washington, where he resides. He is
    barred from litigating in the latter district “absent leave of court”
    because he has filed “an unending string” of “vexatious” lawsuits
    there. State Defs.’ Mot. to Dismiss, Dkt. No. 3, Ex. 1 at 4 (district
    court order); see In re West, 552 F. App’x 624, 625 (9th Cir. 2014)
    (unpublished memorandum) (affirming order).

    response” to the state’s legalization of recreational marijuana.
    Compl. 18-19.
    The district court dismissed the complaint, concluding
    (inter alia) that West lacks standing. We agree. First, for his
    commandeering claim, West has not sufficiently alleged that
    setting aside the Cole Memorandum would redress his alleged
    injuries from the wider availability of recreational marijuana
    and new restrictions on medical marijuana. Second, for his
    NEPA claim, West has not sufficiently alleged that any adverse
    environmental effects of recreational marijuana on his own
    particularized interests are traceable to the memorandum. We
    therefore uphold the dismissal of his complaint. 2
    2
    The district court dismissed the complaint in two separate
    orders. It first ordered dismissal as to the state defendants for lack
    of personal jurisdiction. 
    60 F. Supp. 3d 190
    , 193-96 (D.D.C. 2014).
    It did not address West’s standing and was not required to do so:
    personal jurisdiction and standing are both “essential element[s] of
    the jurisdiction of a district court,” Ruhrgas AG v. Marathon Oil Co.,
    
    526 U.S. 574
    , 584 (1999) (internal quotation and ellipses omitted);
    see Steel 
    Co., 523 U.S. at 102
    , and neither the Supreme Court nor our
    Court “dictate[s] a sequencing of jurisdictional issues[,]” Ruhrgas
    
    AG, 526 U.S. at 584
    ; see Anderson v. Carter, 
    802 F.3d 4
    , 9-10 (D.C.
    Cir. 2015). Several months later, the court ordered dismissal as to
    the federal defendants on the ground that West lacks standing. 60 F.
    Supp. 3d 197, 200-03 (D.D.C. 2015). Because our analysis of
    standing applies equally to the state and federal defendants, we
    affirm the dismissal as to all defendants for West’s lack of standing
    without considering personal jurisdiction. See Parsi v. Daioleslam,
    
    778 F.3d 116
    , 126 (D.C. Cir. 2015) (“Ordinarily, a court of appeals
    can affirm a district court judgment on any basis supported by the
    record, even if different from the grounds the district court cited.”).
    5
    I. BACKGROUND
    For our review, the facts are undisputed. We recite them
    primarily from West’s complaint, accepting as true its
    well-pleaded factual allegations and drawing all reasonable
    inferences in West’s favor. Arpaio v. Obama, 
    797 F.3d 11
    , 19
    (D.C. Cir. 2015). As necessary, we cull additional facts from
    other parts of the record. See Settles v. U.S. Parole Comm’n,
    
    429 F.3d 1098
    , 1107 (D.C. Cir. 2005) (in deciding subject
    matter jurisdiction, court may “consider[] facts developed in
    the record beyond the complaint”). Before turning to the
    injuries alleged in the complaint, we summarize the regulatory
    backdrop against which they must be evaluated.
    A. WASHINGTON’S MARIJUANA LAWS AND
    THE COLE MEMORANDUM
    Since 1970, the CSA has made it a crime to manufacture,
    distribute or possess with intent to distribute controlled
    substances, 21 U.S.C. § 841(a)(1), including marijuana, 
    id. § 812(c)
    (Schedule I(c)(10)). In late 1998, notwithstanding the
    CSA, Washington legalized the medical use of marijuana.
    Act of Nov. 3, 1998, ch. 2, 1999 Wash. Sess. Laws 1. 3
    Starting in 2011, a “qualifying patient” could join together with
    up to nine other qualifying patients to grow marijuana in a
    “collective garden” and transport the product for medical use.
    Act of Apr. 29, 2011, ch. 181, 2011 Wash. Sess. Laws 1345,
    1355. A qualifying patient could possess up to 24 ounces of
    useable marijuana at a time. 
    Id. at 1353.
    3
    Washington’s     session    laws   are    available    at
    leg.wa.gov/codereviser/pages/session_laws.aspx. Its laws relating
    to marijuana are primarily codified at chapters 69.50, 69.51 and
    69.51A of the Revised Code of Washington.
    6
    In November 2012, Washington voters approved Initiative
    502 (I-502), which legalized the recreational use of marijuana.
    Act of Nov. 6, 2012, ch. 3, 2013 Wash. Sess. Laws 28. I-502
    set up a licensing regime for marijuana producers, processors
    and retailers. 
    Id. at 33-52.
    It also provided for a marijuana
    excise tax and subjected retail marijuana sales to ordinary sales
    tax. 
    Id. at 52-53.
    With the exception of a broad prohibition
    on using marijuana or marijuana-infused products “in view of
    the general public,” 
    id. at 44,
    I-502 did not modify the regime
    governing medical marijuana that had existed since the late
    1990s, including provisions permitting the possession of up to
    24 ounces of medical marijuana and allowing for the creation
    of collective gardens. Instead I-502 provided that any user
    over the age of 21 can, without violating “any . . . provision of
    Washington state law,” possess up to one ounce of useable
    marijuana. Id.; see 
    id. at 42.
    In early 2013, Washington Governor Jay Inslee met with a
    White House official to seek assurances that the federal
    government did not intend to “preempt[] . . . state
    implementation of I-502, or pursue enforcement of federal
    criminal laws” in Washington “for those acting legally under
    [state] law.” Pl.’s Supplemental Decl. and Exs. (Decl.), Dkt.
    No. 16 at 81. To the same end, Governor Inslee wrote a letter
    to Eric Holder, then-Attorney General of the United States,
    summarizing the regulatory and law enforcement strategies the
    state planned to implement in the wake of I-502.
    In a letter dated August 29, 2013, Attorney General Holder
    informed Governor Inslee—and Governor John Hickenlooper
    of Colorado, another state that had legalized the recreational
    use of marijuana—that “while the Department will not at this
    time seek to challenge your state’s law, we will nevertheless
    continue to enforce the Controlled Substances Act in your
    state.” Decl. 71. The Attorney General also enclosed the
    7
    Cole Memorandum, which was issued that same day to all
    United States Attorneys.
    The Cole Memorandum updated marijuana-related CSA
    guidances earlier issued to federal prosecutors in 2009 and
    2011. 4 The memorandum “applies to all federal enforcement
    activity . . . concerning marijuana in all states.” Decl. 72. It
    is “solely . . . a guide to the exercise of investigative and
    prosecutorial discretion” and “does not alter in any way the
    Department’s authority to enforce federal law . . . regardless of
    state law.” 
    Id. at 75.
    It advises federal prosecutors “to
    review marijuana cases on a case-by-case basis” in deciding
    how to deal with “marijuana-related activity.” 
    Id. at 74.
    It
    directs them to “weigh all available information and evidence,”
    including whether the activity “is demonstrably in compliance
    with a strong and effective state regulatory system.” 
    Id. It declares
    that “enforcement of state law by state and local law
    enforcement and regulatory bodies should remain the primary
    means of addressing marijuana-related activity” unless the
    state’s “regulatory structure” and “enforcement efforts” “are
    not sufficiently robust.” 
    Id. That arrangement
    is meant to
    enable federal prosecutors to focus on “enforcement priorities
    that are particularly important to the federal government[,]”
    including prevention of violence, organized crime, interstate
    distribution, distribution to minors and use on federal property.
    
    Id. at 72-73.
    Finally, the memorandum states that, if
    marijuana-related activity “interferes with any one or more of
    4
    As relevant here, the earlier guidance advised federal
    prosecutors not to “focus federal resources in [their] States on
    individuals whose actions are in clear and unambiguous compliance
    with existing state laws providing for the medical use of marijuana.”
    United States v. Canori, 
    737 F.3d 181
    , 183 (2d Cir. 2013) (quoting
    2009 guidance) (alteration in original) (internal quotation marks
    omitted).
    8
    these priorities,” federal prosecution may be warranted
    “regardless of state law.” 
    Id. at 73.
    In the first few years after Washington voters approved
    I-502, medical marijuana and recreational marijuana were
    governed by two parallel strands of Washington law, neither of
    which mentioned the other. As noted earlier, a user of
    medical marijuana could grow it in a collective garden with
    other patients and could possess up to 24 ounces. 2011 Wash.
    Sess. Laws at 1353, 1355. A recreational user, by contrast,
    could possess only one ounce. 2013 Wash. Sess. Laws at 42,
    44. In April 2015, the Washington legislature amended the
    two strands of law and partially pulled them together through
    enactment of the Cannabis Patient Protection Act (CPPA), ch.
    70, 2015 Wash. Sess. Laws 287 (Apr. 24, 2015). The CPPA is
    “a comprehensive act that uses the regulations in place for the
    recreational market to provide regulation for the medical use of
    marijuana.” 
    Id. at 288.
    In some ways, the CPPA is more
    restrictive than earlier laws. It repealed the provision that
    permitted a medical user to possess up to 24 ounces of useable
    marijuana. 
    Id. at 317.
    Now the ordinary medical user may
    not possess more than three ounces purchased at retail and
    eight additional ounces obtained from home-grown plants. 
    Id. at 312,
    317 (codified at WASH. REV. CODE §§
    69.51A.040(1)(a) and 69.51A.210(1) (2016)). The CPPA
    also repealed the system of collective gardens, 
    id. at 336,
    replacing it with a system of “cooperative[s]” under which
    “[n]o more than four qualifying patients” may cooperatively
    grow marijuana for medical use, 
    id. at 319
    (codified as
    amended at WASH. REV. CODE § 69.51A.250(1) (2016)).
    Cooperatives are subject to registration requirements and other
    restrictions to which collective gardens were not. Compare
    WASH. REV. CODE § 69.51A.085 (repealed 2016) (collective
    gardens), with 
    id. § 69.51A.250
    (2016) (cooperatives). The
    9
    CPPA took effect in stages during 2015 and 2016. 2015
    Wash. Sess. Laws at 336.
    B. WEST’S COMPLAINT
    In April 2014, after the Cole Memorandum was issued but
    before the CPPA was enacted, West filed his complaint in
    district court. 5 His claims are difficult to discern but the crux
    is that, through the “policy” announced in the memorandum,
    the federal defendants “improperly commandeer[ed]” the state
    defendants and other “[s]tate officers and institutions” in
    violation of the Tenth Amendment and other provisions of the
    United States Constitution. Compl. 1-2 (citing Printz v.
    United States, 
    521 U.S. 898
    (1997); New York v. United States,
    
    505 U.S. 144
    (1992)). West also claimed that all of the
    defendants violated NEPA by failing to prepare an
    environmental impact statement before undertaking the “major
    federal action” announced in the memorandum. 
    Id. at 2,
    17
    (citing 40 C.F.R. § 1508.18) (capitalization altered).
    According to the complaint, the memorandum subjects West to
    injuries from the wider availability of recreational marijuana
    and by limiting his access to medical marijuana. We briefly
    summarize West’s allegations about each type of injury.
    Wider availability of recreational marijuana. West
    opposed I-502. He frequents a park in Olympia that is
    “suffering under the impacts of homelessness and casual
    recreational drug use.” Compl. 4. Implementation of I-502,
    as “sanctioned” by the Cole Memorandum, “will” cause a
    surge in drug use, further “degrad[ing]” the park. 
    Id. at 14.
    Moreover, because I-502 authorizes “an entirely new
    commercial market” in marijuana, it “will” eventually cause
    5
    The complaint amended an earlier version filed in January
    2014. No party claims the earlier version affects our analysis.
    10
    more “crime, traffic, noise, air pollution, and cumulative
    impacts.” 
    Id. Limited access
    to medical marijuana. West holds a
    medical marijuana authorization, uses marijuana for medical
    purposes and is an “independent consultant” in that field.
    Compl. 4, 13. The Cole Memorandum “will” have the
    “foreseeable and imminent effect[s]” of limiting his access to
    medical marijuana and making it more expensive for him,
    inasmuch as state legislators have referred to the memorandum
    in proposing legislation “sharply regulat[ing]” medical
    marijuana and subjecting it to new taxes. 
    Id. at 12-13.
    6
    In the complaint’s prayer for relief, West asked the district
    court to declare the Cole Memorandum “void” and to
    “compel[]” all of the defendants “to comply with . . . NEPA” in
    connection with the “federal . . . response” to Washington’s
    legalization of recreational marijuana. Compl. 18-19. The
    defendants moved to dismiss the complaint, contending (inter
    alia) that West lacks standing. West opposed their motions
    but did not explain how the relief he requested would redress
    his alleged injuries.
    C. THE DISTRICT COURT’S DISMISSAL OF THE COMPLAINT
    The district court dismissed the complaint, concluding
    (inter alia) that “West has not established that he has Article III
    standing to bring any of his various claims to federal court.”
    
    60 F. Supp. 3d 197
    , 200 (D.D.C. 2015); see supra note 2.
    Reciting the three elements of standing—(1) a particularized
    injury to the plaintiff (2) traceable to the defendants’
    6
    The proposed legislation cited in the complaint was not
    enacted but presaged the CPPA, which, as noted, was enacted after
    West filed his complaint.
    11
    challenged conduct and (3) redressable by a favorable
    decision—the court held that West did not sufficiently plead
    any of 
    them. 60 F. Supp. 3d at 200-03
    . First, in the court’s
    view, West’s allegations that the Cole Memorandum “will”
    produce more crime, traffic and pollution and “will” limit his
    access to medical marijuana were inadequate “speculative
    predictions.” 
    Id. at 201
    (internal quotations and emphases
    omitted). Second, the court reasoned that West’s alleged
    injuries could not “fairly . . . be traced” to the memorandum,
    which was issued well after I-502 became law and which
    merely “allow[s]” the allegedly harmful actions of third parties
    not involved in the suit. 
    Id. (internal quotation
    omitted).
    Third, the court held that because West “made no effort to
    show that his injuries can be redressed” in federal court, he
    “forfeited any arguments he might have had” on that issue. 
    Id. at 202-03
    & n.5. The court added that any claim of
    redressability would fail in any event because it was “purely
    speculative” that voiding the memorandum would “modify
    Washington’s . . . allegedly harmful marijuana policies.” 
    Id. (internal quotation
    omitted). 7
    West appealed and this Court appointed amicus curiae to
    present arguments in support of his position. West adopts
    amicus’s arguments without asserting any additional
    non-frivolous contention regarding his standing.
    II. ANALYSIS
    Because “standing is not dispensed in gross” but instead
    may differ claim by claim, Davis v. FEC, 
    554 U.S. 724
    , 734
    7
    In a subsequent order denying reconsideration, the district
    court clarified that its standing analysis applied not only to West’s
    commandeering claim but to his NEPA claim as well. 
    309 F.R.D. 54
    , 59 (D.D.C. 2015).
    12
    (2008) (internal quotation and alteration omitted), we address
    seriatim West’s standing to pursue his commandeering and
    NEPA claims. Reviewing the district court’s decision de
    novo, Teton Historic Aviation Found. v. Dep’t of Defense, 
    785 F.3d 719
    , 724 (D.C. Cir. 2015) (per curiam), we conclude that
    West lacks standing to assert both claims.
    A. COMMANDEERING
    For West’s claim that the Cole Memorandum
    “commandeer[s]” state officials and otherwise violates the
    Constitution, Compl. 1, 17-18, we need not decide whether he
    has adequately pleaded any particularized injury traceable to
    the memorandum because he has not sufficiently alleged
    redressability. 8 See Huron v. Cobert, 
    809 F.3d 1274
    , 1279
    (D.C. Cir. 2016) (plaintiff “bear[s] the burden of establishing
    each of [the] elements of standing”).          “Redressability
    examines whether the relief sought, assuming that the court
    8
    We observe, however, that West’s and amicus’s assertions of
    injury from new restrictions on medical marijuana are
    chronologically problematic. The CPPA is the primary source of
    those restrictions and it postdates West’s complaint. Because “a
    party must show a legally cognizable injury to have standing to begin
    a lawsuit,” Garden State Broad. Ltd. P’ship v. FCC, 
    996 F.2d 386
    ,
    394 (D.C. Cir. 1993), “[s]tanding is determined as of the time the
    action is brought,” Nova Health Sys. v. Gandy, 
    416 F.3d 1149
    , 1154
    (10th Cir. 2005) (citing cases). We therefore question the CPPA’s
    relevance to West’s standing. Amicus suggests remanding the case
    so that West can amend the complaint to account for the CPPA and
    other developments. There is no need. In view of our conclusion
    about redressability, amending the complaint would only delay the
    inevitable. Cf. Hettinga v. United States, 
    677 F.3d 471
    , 480 (D.C.
    Cir. 2012) (per curiam) (“A district court may deny a motion to
    amend a complaint as futile if the proposed claim would not survive
    a motion to dismiss.”).
    13
    chooses to grant it, will likely alleviate the particularized injury
    alleged by the plaintiff.” Fla. Audubon Soc’y v. Bentsen, 
    94 F.3d 658
    , 663-64 (D.C. Cir. 1996) (en banc) (footnote
    omitted). The key word is “likely.” Lujan v. Defenders of
    Wildlife, 
    504 U.S. 555
    , 561 (1992) (“[I]t must be likely, as
    opposed to merely speculative, that the injury will be redressed
    by a favorable decision.” (internal quotation omitted)). As
    relief on his commandeering claim, West asks that the Cole
    Memorandum be declared “void.” Compl. 19. But his
    complaint and oppositions to the defendants’ motions to
    dismiss did not even begin to explain how voiding the
    memorandum would likely clean up the park he visits; reduce
    crime, traffic and pollution more generally; or cause
    Washington to ease its restrictions on medical marijuana. Nor
    has amicus closed the gap in this Court.9
    Amicus’s argument in a nutshell is that redressability
    necessarily “follows from causation.” Amicus Br. 40; see 
    id. at 30-31.
    Not so. It is true that causation and redressability
    “are closely related” like “two sides of a . . . coin.” Dynalantic
    Corp. v. Dep’t of Defense, 
    115 F.3d 1012
    , 1017 (D.C. Cir.
    1997). Like heads and tails, however, the two concepts are
    distinct: causation focuses on the “connection between the
    assertedly unlawful conduct and the alleged injury” whereas
    redressability focuses on the “connection between the alleged
    9
    In saying so, we by no means denigrate amicus, who
    provided exemplary briefing and oral argument in service of an
    unwinnable cause. Indeed, even if amicus had fashioned a viable
    theory of redressability, it would not have aided West, who
    preserved no such theory in district court.

    injury and the judicial relief requested.” Allen v. Wright, 
    468 U.S. 737
    , 753 n.19 (1984). If the challenged conduct is at best
    an indirect or contributing cause of the plaintiff’s injury—i.e.,
    if the injury may or may not follow from the conduct, based on
    a “chain of contingencies,” Clapper v. Amnesty Int’l USA, 568
    U.S. __, 
    133 S. Ct. 1138
    , 1148 (2013)—the plaintiff faces an
    uphill climb in pleading and proving redressability. Arpaio v.

    797 F.3d 11
    , 21 (D.C. Cir. 2015) (“When considering
    any chain of allegations for standing purposes, we may reject
    as overly speculative those links which are predictions of
    future events[,] especially future actions to be taken by third
    parties . . . .” (internal quotation and parentheses omitted));
    Nat’l Wrestling Coaches Ass’n v. Dep’t of Educ., 
    366 F.3d 930
    ,
    938 (D.C. Cir. 2004) (“[A] plaintiff’s standing fails where it is
    purely speculative that a requested change in government
    policy will alter the behavior of regulated third parties that are
    the direct cause of the plaintiff’s injuries.”).
    Our National Wrestling Coaches decision illustrates the
    principle. In that case, organizations representing male
    collegiate wrestlers and coaches challenged regulatory
    guidance implementing Title IX of the Education Amendments
    of 1972, 20 U.S.C. §§ 1681 et seq. The guidance prescribed a
    three-part test for measuring compliance with an earlier
    requirement that schools provide “equal athletic opportunity
    for members of both 
    sexes.” 366 F.3d at 934-35
    (quoting 34
    C.F.R. § 106.41(c) and 45 C.F.R. § 86.41(c)). According to
    the plaintiff organizations, some schools passed the test “not by
    offering increased athletic opportunities to female students, but
    by reducing the opportunities available to male students,”
    including by eliminating men’s varsity wrestling. 
    Id. at 937.
    We affirmed the district court’s dismissal of the suit for lack of
    standing because the plaintiffs could not establish
    redressability. 
    Id. at 936-45.
    Setting aside the challenged
    guidance, we reasoned, would not undo the underlying
    15
    equal-opportunity requirement or prevent the schools from
    exercising their own “discretion to eliminate men’s wrestling
    programs, as necessary, to comply with” the requirement. 
    Id. at 933.
    And the plaintiffs “offer[ed] nothing but speculation”
    that “a favorable judicial decision” would alter the schools’
    “independent choices” on that score. 
    Id. A similar
    analysis here yields a similar conclusion. The
    direct causes of West’s alleged injuries—e.g., recreational
    users who smoke marijuana in public and state officials who
    restrict his access to medical marijuana—are not governed by
    the Cole Memorandum but by state laws he does not challenge.
    The memorandum governs only federal prosecutors and even
    as to them, only loosely: it is mere guidance channeling their
    prosecutorial discretion, advising them to rely on state
    authorities to address marijuana activity unless the state’s
    regulatory system is insufficiently robust or the particular
    activity implicates a federal enforcement priority. If the
    memorandum no longer existed, would federal prosecutors
    expend their limited resources cracking down on the use of
    recreational marijuana in Washington? West’s allegations
    offer no basis to conclude that they would. 10 Would an uptick
    in federal prosecutions dissuade scofflaws from publicly
    smoking marijuana in the park West frequents? Given that
    those offending marijuana users have already chosen to defy
    state law, see 2013 Wash. Sess. Laws at 44, any such allegation
    would be implausible. Similarly, if federal prosecutors began
    10
    Even before the Cole Memorandum, prosecutors were
    advised not to “focus federal resources in [their] States on
    individuals whose actions are in clear and unambiguous compliance
    with existing state laws providing for the medical use of marijuana.”
    United States v. Canori, 
    737 F.3d 181
    , 183 (2d Cir. 2013) (quoting
    2009 guidance) (alteration in original) (internal quotation marks
    omitted); see supra note 4 and accompanying text.
    16
    pursuing more CSA charges in Washington, would that
    encourage state legislators to loosen their recent restrictions on
    medical marijuana? Common sense hardly dictates such a
    result and, in any event, West fails to explain why it is likely to
    occur.
    When conjecture is necessary, redressability is lacking.
    Simon v. E. Ky. Welfare Rights Org., 
    426 U.S. 26
    , 43-44
    (1976). To find redressability on West’s commandeering
    claim, we would have to pile conjecture on conjecture, much of
    it about the charging decisions of federal prosecutors. Courts
    do not lightly speculate how “independent actors not before
    [them]” might “exercise [their] broad and legitimate
    discretion,” 
    Lujan, 504 U.S. at 562
    (internal quotation
    omitted), especially when the independent actors are federal
    prosecutors, United States v. Armstrong, 
    517 U.S. 456
    , 464
    (1996) (because prosecutors are “delegates” who help
    President “discharge his constitutional responsibility to ‘take
    Care that the Laws be faithfully executed,’” charging decisions
    “‘generally rest[] entirely in [their] discretion’” (quoting U.S.
    CONST. art. II, § 3, and Bordenkircher v. Hayes, 
    434 U.S. 357
    ,
    364 (1978))); Heckler v. Chaney, 
    470 U.S. 821
    , 831 (1985)
    (“decision not to prosecute” ordinarily not subject to judicial
    review). Neither West nor amicus gives us any good reason to
    depart from these settled principles here. And we decline to
    do so especially because, even if we were to set aside the Cole
    Memorandum, we would not and could not compel the
    Department to alter the enforcement priorities that the
    memorandum merely documented.
    B. NEPA
    Analysis of West’s standing to assert a NEPA claim
    differs from that of his standing to assert a constitutional
    violation. But the result is the same.
    17
    A NEPA plaintiff can assert a violation of the statute
    “without meeting all the normal standards for redressability
    and immediacy.” City of Dania Beach v. FAA, 
    485 F.3d 1181
    ,
    1186 (D.C. Cir. 2007) (quoting 
    Lujan, 504 U.S. at 572
    n.7)
    (internal quotation marks omitted). For example, the plaintiff
    need not allege that, if he were to succeed in enforcing a
    NEPA-required procedure the defendant agency did not
    follow, the agency’s substantive policy would change. 
    Id. Here, then,
    West need not aver that, if the Department or other
    defendants were ordered to prepare an environmental impact
    statement about the likely effects of the Cole Memorandum,
    the memorandum would instead be withdrawn.
    A NEPA plaintiff is not absolved, however, from pleading
    and proving “a causal connection between the [substantive]
    agency action and the alleged injury.” City of Dania 
    Beach, 485 F.3d at 1186
    ; see Fla. Audubon 
    Soc’y, 94 F.3d at 664-65
    (NEPA claimant or other procedural-rights plaintiff must
    “show[] a causal connection between the government action
    that supposedly required the disregarded procedure” and “the
    essential injury to the plaintiff’s own interest”). West does
    not meet the causation requirement.
    West claims that, before publication of the Cole
    Memorandum, NEPA required the defendants to determine
    what effect the memorandum’s “sanction[ing]” of I-502 would
    have on Washington’s environment. Compl. 14, 17-18. But
    he cannot connect the memorandum to his alleged injuries
    from recreational marijuana, chief among them the
    “degrad[ation]” of the park he visits. 
    Id. at 14.
    As the state
    defendants’ counsel noted at oral argument, I-502 “is itself a
    statute” and “was the law for about a year before the Cole
    Memo was issued.” Oral Arg. Recording 25:18-25:50. Also,
    Washington had begun the process of implementing I-502 well
    before the memorandum existed. Given that sequence, and
    18
    because I-502 governs recreational users directly, we think
    I-502 a much more likely source of West’s alleged injuries.
    We can only speculate that the Cole Memorandum—issued to
    third-party prosecutors who retain discretion to prosecute
    marijuana activity “on a case-by-case basis,” Decl. 74—had
    anything to do with the alleged injuries. And just as
    speculation cannot establish redressability, it cannot establish
    causation.

    For the foregoing reasons, we affirm the district court’s
    dismissal of the complaint.
    So ordered.
