    *   Of the District of Rhode Island, sitting by designation.
    BARRON, Circuit Judge.          Mohamed Abdulaziz ("Abdulaziz")
    challenges his five-year prison sentence for committing a federal
    firearms offense in violation of 
    18 U.S.C. § 922
    (g).           He contends
    that the District Court erred in applying the enhancement set forth
    in § 2K2.1(a)(2) of the United States Sentencing Guidelines to him
    at his sentencing.      That guideline subjects a defendant who has
    been convicted of a § 922(g) offense to a higher base offense level
    ("BOL")   under   the   Guidelines    if    he   committed   that   offense
    "subsequent to sustaining at least two felony convictions of either
    a crime of violence or a controlled substance offense."             U.S.S.G.
    § 2K2.1(a)(2).    The question that we must decide turns on a purely
    legal question:    what constitutes a "controlled substance" within
    the meaning of this guideline?             Because we conclude that the
    District Court erred in resolving it, we vacate the judgment
    imposing the sentence and remand the case for further proceedings.
    I.
    On January 3, 2019, a federal grand jury in the District
    of Massachusetts indicted Abdulaziz on one count of possession of
    a firearm and ammunition by a prohibited person in violation of 
    18 U.S.C. § 922
    (g)(1).        The charged conduct was alleged to have
    occurred on September 2, 2018.        Abdulaziz pleaded guilty to the
    offense on June 13, 2019.
    The     United    States    Probation     Office    prepared     a
    presentence investigation report ("PSR").         Among other things, the
    - 2 -
    PSR calculated Abdulaziz's Guidelines Sentencing Range ("GSR") for
    his § 922(g) offense.            The PSR based the calculation in part on
    the application of the § 2K2.1(a)(2) enhancement.
    The PSR determined that the enhancement applied based on
    three state law felony convictions that Abdulaziz had sustained
    before he committed the § 922(g) offense. The PSR determined that,
    under the guideline, two of those convictions were of "crime[s] of
    violence"    and    one    was    of   "a   controlled     substance   offense."
    U.S.S.G. § 2K2.1(a)(2).
    At     the    sentencing     hearing   on    September     26,   2019,
    Abdulaziz did not dispute the PSR's determination that his January
    2010 Massachusetts conviction of assault with a dangerous weapon
    (firearm) in violation of Mass. Gen. Laws ch. 265, § 15B(b) --
    which he sustained prior to committing the § 922(g) offense --
    qualified under § 2K2.1(a)(2) as a "felony conviction[]" of "a
    crime of violence."          The District Court noted at the hearing,
    however, that the government was "not arguing" that the other
    conviction   that        Abdulaziz     sustained   prior    to   committing   the
    § 922(g) offense and that the PSR had determined qualified as a
    "felony conviction[]" of "a crime of violence" -- his April 2018
    Massachusetts conviction for unarmed assault with intent to rob in
    violation of 
    Mass. Gen. Laws ch. 265, § 20
     -- also qualified as
    such a "felony conviction[]" of "a crime of violence."
    - 3 -
    Thus,    the   application     of   the    enhancement      turned   on
    whether the third state law felony conviction that Abdulaziz
    sustained prior to committing the § 922(g) offense and that the
    PSR had determined was of a qualifying offense -- namely, his July
    2014   Massachusetts       conviction    for    possession      with    intent   to
    distribute "Marihuana," which the underlying state statute defined
    to be a "controlled substance," Mass. Gen. Laws ch. 94C, §§ 31,
    Class D(b)(1), 32C(a) (effective July 1, 2014) -- qualified as a
    "felony conviction[]" of "a controlled substance offense" under
    § 2K2.1(a)(2). For, if it did, then Abdulaziz would have committed
    the § 922(g) offense "subsequent to sustaining at least two felony
    convictions of either a crime of violence or a controlled substance
    offense."    U.S.S.G. § 2K2.1(a)(2).
    The District Court sided with the government and against
    Abdulaziz by ruling that this July 2014 Massachusetts conviction
    did so qualify.         The District Court            accordingly      applied the
    enhancement and determined Abdulaziz's BOL to be 24, rather than
    either 22 or 20 as it would have been if the enhancement did not
    apply.    See U.S.S.G. § 2K2.1(a)(3)-(4) (providing for a BOL level
    of either 22 or 20 when the defendant has only one qualifying prior
    conviction, depending on the nature of the firearm involved in the
    § 922(g) offense).
    The     District   Court    next    adjusted    Abdulaziz's      total
    offense     level    downward    due     to     his    timely    acceptance      of
    - 4 -
    responsibility.        See U.S.S.G. § 3E1.1(a), (b).           After accounting
    for Abdulaziz's criminal history category, which it determined to
    be VI, the District Court calculated his GSR to be 77 to 96 months
    of imprisonment.       The District Court at that point determined that
    Abdulaziz was eligible for a departure pursuant to § 4A1.3(b) of
    the Guidelines.1       The departure resulted in a recalculated GSR of
    57 to 71 months of imprisonment.                The District Court ultimately
    sentenced Abdulaziz to a sixty-month prison term to be followed by
    three years of supervised release.
    Judgment was entered on September 26, 2019.                 Abdulaziz
    timely appealed on October 7, 2019.
    II.
    Abdulaziz     contends      that     his   sentence    cannot     stand
    because his July 2014 Massachusetts conviction for possession with
    intent to distribute "Marihuana," Mass. Gen. Laws ch. 94C, §§ 31,
    Class D(b)(1), 32C(a) (effective July 1, 2014), does not qualify
    as   a    conviction    of   "a    controlled      substance      offense"    under
    § 2K2.1(a)(2).
    Setting     aside     for   the   moment   the   question    of   what
    criteria the guideline uses to determine what constitutes what it
    1The District Court reasoned that, in light of the age of
    some of Abdulaziz's prior convictions and the lack of recent
    serious offenses, "he's more properly classified in criminal
    history category IV" and thus it "depart[ed] from criminal history
    category VI to criminal history category IV."
    - 5 -
    terms "a controlled substance offense," we note that there is no
    disagreement between the parties that this guideline requires that
    we apply the categorical approach to determine whether Abdulaziz's
    July 2014 Massachusetts conviction was of "a controlled substance
    offense" within the meaning of § 2K2.1(a)(2).           In consequence, we
    "look only to the elements" of the Massachusetts law offense
    underlying that conviction and "not to 'how [Abdulaziz] actually
    perpetrated the crime to decide if the offense, as defined in the
    statute, matches [the guideline's] criteria' for a 'controlled
    substance offense.'"        United States v. Capelton, 
    966 F.3d 1
    , 6
    (1st Cir. 2020) (quoting United States v. García-Cartagena, 
    953 F.3d 14
    , 18 (1st Cir. 2020)).
    We also note that there is no disagreement between the
    parties that, at the time of Abdulaziz's July 2014 conviction for
    that      "Marihuana"-related      offense,      Massachusetts      defined
    "Marihuana" to include hemp.        See Mass. Gen. Laws ch. 94C, § 1
    (effective July 1, 2014) (defining "Marihuana" as "all parts of
    the plant Cannabis sativa L., whether growing or not," except for
    "the mature stalks of the plant, fiber produced from the stalks,
    oil, or cake made from the seeds of the plant").            Accordingly, the
    parties    agree   that   Abdulaziz's   July   2014    conviction   must   be
    understood to be a conviction for possession with the intent to
    distribute hemp even though the record does not establish whether
    Abdulaziz    actually     perpetrated   that   crime   by   possessing   that
    - 6 -
    substance.         See Moncrieffe v. Holder, 
    569 U.S. 184
    , 190-91 (2013)
    (explaining that under the categorical approach a court is to look
    to   "the    least     of      the   acts"    criminalized         by    the    statute   of
    conviction (alteration omitted) (quoting Johnson v. United States,
    
    559 U.S. 133
    , 137 (2010)).
    With this foundation in place, we have but one question
    to decide to resolve this appeal:                   is a conviction of such a hemp-
    based offense a conviction of "a controlled substance offense"
    within the meaning of § 2K2.1(a)(2)?                   As that question necessarily
    turns on the proper interpretation of the Guidelines, our review
    is de novo.        See Capelton, 996 F.3d at 5.
    A.
    "[W]e ordinarily employ the Guidelines in effect at
    sentencing," rather than the Guidelines in effect either at the
    time of the defendant's conviction of the offense for which he is
    being    sentenced        or    at   any     earlier      time.      United      States    v.
    Rodriguez, 
    630 F.3d 39
    , 42 (1st Cir. 2010) (alteration omitted)
    (quoting United States v. Maldonado, 
    242 F.3d 1
    , 5 (1st Cir.
    2001)); see 
    18 U.S.C. § 3553
    (a)(4)(A)(ii).                        We follow that course
    here, and, indeed, no party asks us to do otherwise.                           We thus must
    decide      what    the     term     "controlled       substance        offense"    in    the
    § 2K2.1(a)(2)        guideline        meant    as    of   the     time    of   Abdulaziz's
    § 922(g) sentencing.
    - 7 -
    The text of § 2K2.1(a)(2) at that time did not purport
    to define the term "controlled substance offense," just as it does
    not purport to do so now.                 See U.S.S.G. §§ 2K2.1(a)(2).             But, it
    did    refer      at   that    time    --    as   now    --    to   another   guideline,
    § 4B1.2(b), that did define that term.                        See id. §§ 2K2.1(a)(2) &
    cmt. n.1, 4B1.2(b).              And, that guideline defined "controlled
    substance offense" at that time -- as now -- as an "offense" that,
    among      other   things,      "prohibits the .          .    . possession       of   [with
    intent       to    distribute]        a     controlled        substance."         U.S.S.G.
    § 4B1.2(b) (emphasis added).                Moreover, the government agrees with
    Abdulaziz (given the arguments that it has timely made to us) that
    a "controlled substance" in § 4B1.2(b) was defined as of that time
    by reference to whether a substance was either included in or
    excluded       from    the     drug    schedules        set    forth   in   the    federal
    Controlled Substances Act ("CSA").2 See 
    21 U.S.C. § 812
    ; 
    21 C.F.R. §§ 1308.11-1308.15
    .             Thus, insofar as the CSA's drug schedules
    were       incorporated       into    the   guideline         itself   at   the   time   of
    The government filed a response to a Rule 28(j) letter after
    2
    briefing was complete in this case in which it took the position
    for the first time that "the term 'controlled substance' in USSG
    § 4B1.2 [does not] refer[] exclusively to the federal controlled
    substance[s]" listed in the CSA's drug schedules. We decline to
    address such a late-breaking contention about the criteria that
    the Guidelines use to define what constitutes a "controlled
    substance." See Rosa-Rivera v. Dorado Health, Inc., 
    787 F.3d 614
    ,
    617 (1st Cir. 2015) ("Not only is it improper to advance new
    arguments in a 28(j) letter, but it is far too late in the game."
    (citation omitted)).
    - 8 -
    Abdulaziz's § 922(g) sentencing, it would appear that the answer
    to our question is fairly straightforward:                we must look to the
    version of those drug schedules that were "in effect" at that time,
    Rodriguez,   
    630 F.3d at 42
    ,   to   determine   what   constituted   a
    "controlled substance," U.S.S.G. § 4B1.2(b), at that time.
    To be sure, the CSA's drug schedules do, by design,
    change over time.        See 
    21 U.S.C. §§ 811
    (a), 812(a) ("There are
    established five schedules of controlled substances . . . [which]
    shall initially consist of the substances listed in this section,"
    but "the Attorney General may by rule" "add" "or" "remove any drug
    or other substance from the schedules [provided that certain
    findings are made]." (emphasis added)).             And that does mean that,
    insofar as § 4B1.2(b) incorporated the CSA's drug schedules as of
    the time of Abdulaziz's § 922(g) sentencing, what constituted a
    "controlled substance" in that guideline as of that time might
    differ from what constituted a "controlled substance" as of the
    time   of   one    of   his    prior     "felony   convictions."       U.S.S.G.
    §§ 2K2.1(a)(2), 4B1.2(b).
    But, of course, the Guidelines themselves are not fixed
    in stone, and yet we ordinarily must apply the version of them
    that is in effect at the time of the defendant's sentencing for
    his conviction of the offense that occasioned it.                See Rodriguez,
    
    630 F.3d at 42
    ; 
    18 U.S.C. § 3553
    (a)(4)(A)(ii).                   Thus, the fact
    that the CSA drug schedules vary over time does not itself suggest
    - 9 -
    a reason for us to look to a version of those schedules that is
    different from the one that was in effect at the time of the
    § 922(g) sentencing to determine what constituted a "controlled
    substance" -- and thus what constituted a "controlled substance
    offense" -- under § 2K2.1(a)(2) as of the time of that sentencing.
    Nonetheless, the government contends that the text of
    § 2K2.1(a)(2) must be read to require that we look to the version
    of the CSA's drug schedules that was in place at some time prior
    to the time of the § 922(g) sentencing to discern what that
    guideline deemed to be a "controlled substance" as of the time of
    that sentencing.     Specifically, the government contends that the
    words "felony conviction[]" and "subsequent to sustaining" in
    § 2K2.1(a)(2) combine to require that the meaning of "controlled
    substance," even as of the time of the § 922(g) sentencing, must
    be drawn from the version of the CSA's drug schedules that was in
    place at the time of either (1) Abdulaziz's commission of the
    § 922(g)   offense   in   September   of   2018,   or   (2)   Abdulaziz's
    sustaining of the hemp-related Massachusetts conviction in July of
    2014, and thus not from the version of those schedules that was in
    effect when he was later sentenced for his § 922(g) conviction.
    From that premise, the government then goes on to contend
    that Abdulaziz's July 2014 Massachusetts conviction necessarily
    was of "a controlled substance offense" within the meaning of
    § 2K2.1(a)(2) as of the time of his § 922(g) sentencing, even
    - 10 -
    though the CSA's drug schedules did not include hemp at the time
    of that sentencing.   See Agriculture Improvement Act of 2018, Pub.
    L. No. 115-334, § 12619, 
    132 Stat. 4490
    , 5018 (effective Dec. 20,
    2018) (codified as amended at 
    21 U.S.C. § 802
    (16)(B)) (providing
    that "[t]he term 'marihuana' does not include" "hemp").           And that
    is because, the government correctly points out, the CSA's drug
    schedules in effect at each of those earlier times (July 2014 and
    September 2018) did include hemp.          See 
    21 U.S.C. § 812
    , Sched.
    I(c)(10) (2012, effective through Dec. 19, 2018); 
    id.
     § 802(16)
    (2009, effective through Dec. 17, 2014); id. (2016, effective
    through Oct. 23, 2018).      For the reasons that we will next explain,
    however, we do not agree with the government's construction of
    § 2K2.1(a)(2), under which CSA drug schedules not in effect at the
    time of a defendant's § 922(g) sentencing would determine the
    meaning of "a controlled substance offense" in that guideline as
    of the time of that sentencing.
    B.
    We begin with the guideline's text and the specific words
    in it that the government contends support the construction that
    it advances.   We note, however, that those words do not expressly
    require such a backward-looking, time-of-prior-conviction or time-
    of-commission-of-§    922(g)-offense       approach   to   discerning   the
    meaning   of   the    term     "controlled     substance     offense"    in
    § 2K2.1(a)(2). The guideline does not refer, for example, to "what
    - 11 -
    at the time of the § 922(g) offense was considered a controlled
    substance offense" or, alternatively, to "what at the time of the
    prior conviction was considered a controlled substance offense."
    Nor must the words that the government places such weight
    on be understood to make such a specification for them to be doing
    any work at all.              Whether or not we construe "a controlled
    substance offense" to be defined by reference to the version of
    § 4B1.2(b) in effect at the time of the § 922(g) sentencing, the
    earlier clause in § 2K2.1(a)(2) would still usefully establish
    that under that guideline the "felony convictions" must have been
    "sustain[ed]"       before      the        § 922(g)       offense    was     "committed."
    U.S.S.G. § 2K2.1(a)(2); cf. United States ex rel. Banigan v.
    PharMerica,    Inc.,      
    950 F.3d 134
    ,     143    n.11    (1st        Cir.   2020)
    (explaining     that      "courts,          whenever        possible,       [attempt]         to
    give meaning to every word and phrase contained in the text of a
    statute"    (quoting      United       States        ex     rel.    Ondis        v.   City    of
    Woonsocket, 
    587 F.3d 49
    , 58 (1st Cir. 2009))).
    To be sure, the word "conviction[]" in § 2K2.1(a)(a)
    does require us to look back to the time of a conviction -- rather
    than to the time of the § 922(g) sentencing itself -- to discern
    the elements of, and the penalties attached to, the offense that
    underlies     it,    so   that        we     may     then    determine       whether         the
    "conviction[]"      is    a     "felony       conviction[]"          of     "a    controlled
    substance offense" as of the time of that sentencing.                                 U.S.S.G.
    - 12 -
    § 2K2.1(a)(2).     That much is clear from McNeill v. United States,
    
    563 U.S. 816
     (2011), on which the government heavily relies.
    But, the word "conviction[]" in the guideline is not the
    word that matters here, given that we are trying to identify this
    guideline's criteria for what constitutes "a controlled substance
    offense."     Nor does McNeill suggest otherwise.
    In McNeill, the Supreme Court considered a provision in
    the Armed Career Criminal Act ("ACCA") that imposed a sentencing
    enhancement for a § 922(g) offender who had three or more "previous
    convictions" of "a serious drug offense."            
    18 U.S.C. § 924
    (e)(1);
    see McNeill,

    .          The Court held that the "plain
    text" of the words "previous conviction" compelled the conclusion
    that   the   elements   of    and   penalties   attached   to   the   offense
    underlying a "previous conviction" were locked in as of the time
    of that "conviction."        McNeill, 
    563 U.S. at 820
    .     Thus, the Court
    held, ACCA's plain text required the sentencing judge to decide
    whether a "previous conviction" of an offense with those time-of-
    conviction characteristics qualified as a "previous conviction" of
    "a serious drug offense" in determining whether the enhancement
    set forth in ACCA applied.          
    Id. at 820-22
    .
    It is clear, as the Sixth Circuit recently observed,
    that "McNeill expresses the principle that the elements of the
    state offense of conviction are locked in at the time of that
    conviction."     United States v. Williams, No. 19-6410, 2021 WL
    - 13 -
    1149711, at *6 (6th Cir. Mar. 25, 2021) (unpublished); see also
    Boulanger v. United States, 
    978 F.3d 24
    , 30 n.6 (1st Cir. 2020)
    ("Congress intended courts to use the 'historical statute of
    conviction' when analyzing ACCA cases, not a modern, amended
    version" (quoting McNeill, 
    563 U.S. at 822
    )).                           That is why,
    consistent with the categorical approach, we look to the elements
    of the Massachusetts law "Marihuana" offense of which Abdulaziz
    was convicted in July 2014, Mass. Gen. Laws ch. 94C, §§ 31, Class
    D(b)(1), 32C(a) (effective July 1, 2014), as Massachusetts law
    described    those     elements    at    the     time    of    that     conviction   to
    determine the characteristics of the offense underlying it.
    But, in making that much clear, McNeill did not also
    hold that ACCA's own criteria for deeming a "previous conviction[]"
    with   those    locked-in       characteristics         to    be   "a   serious    drug
    offense,"      
    18 U.S.C. § 924
    (e)(2)(A)          (emphasis       added),    were
    themselves     also    locked    in   as   of    the     time      of   the   "previous
    conviction[]."        In fact, McNeill simply had no occasion to address
    that question, because there had been no relevant change in that
    case to those criteria -- which included in part a requirement
    that such a conviction carry "a maximum term of imprisonment of
    ten years or more," 
    id.
     -- between the time of the McNeill
    defendant's "previous conviction[]" and the time of his § 922(g)
    sentencing, such as through an amendment during that period to
    ACCA itself, see McNeill, 
    563 U.S. at 817-19
    ; Career Criminals

    ,
    3207-39 to -40 (codified as amended at 
    18 U.S.C. § 924
    (e)(2)).3
    In this appeal, of course, the only question that is in
    dispute is the one that is analogous to the question that the Court
    in McNeill did not have any occasion to answer -- namely, are
    § 2K2.1(a)(2)'s criteria for deeming a "felony conviction[]" to be
    of "a controlled substance offense" locked in at the time of that
    "conviction[]"?   That question is analogous to the question of
    what ACCA's criteria were for determining what constituted "a
    serious drug offense."   And thus, as the Ninth Circuit recognized
    when faced with the same question concerning the criteria that
    this guideline uses to determine whether a prior conviction is a
    qualifying "controlled substance offense" that we now confront, it
    is a question that "bears little resemblance to the [question
    3  Another of ACCA's criteria for deeming a prior state
    conviction to be of "a serious drug offense" included that such a
    conviction   must   "involv[e] manufacturing,    distributing,   or
    possessing with intent to manufacture or distribute, a controlled
    substance (as defined in section 102 of the Controlled Substances
    Act (21 U.S.C. 802))." 
    18 U.S.C. § 924
    (e)(2)(A)(ii). But, there
    had been no relevant intervening change to the meaning of
    "controlled substance" in this provision, as the defendant in
    McNeill had six prior North Carolina convictions for either selling
    cocaine or possessing with intent to sell cocaine, see McNeill,
    
    563 U.S. at 818-19
    , and the defendant did not contend (nor did he
    have any basis for contending) that at any relevant time "cocaine"
    was not a "controlled substance" under the CSA's drug schedules
    and thus under § 924(e)(2)(A)(ii). The McNeill Court thus had no
    occasion to address whether the ACCA enhancement could validly be
    applied to him if "cocaine" were no longer a "controlled substance"
    within the meaning of § 924(e)(2)(A)(ii) at the time of sentencing.

    4In a 28(j) letter filed on May 26, 2021 acknowledging
    Williams, the government points to the concurrence in that case,

    "the overwhelming trend of appellate decisions all point to
    applying sentencing enhancements using a time-of-conviction rule."

    attached to a "conviction" are locked in as of the time of that
    "conviction" and thus, like McNeill, have little to do with the
    question posed here. See United States v. Doran,

    In addition to this distinction between the question
    that we must answer in this case and the question that the Court
    confronted in McNeill, there is another reason why the government's
    reliance on McNeill here is misplaced.       The explanation that
    McNeill gave for concluding that the words "previous conviction[]"
    in ACCA plainly required a backward-looking inquiry into the
    elements of and penalties attached to the prior offense at the
    time of its commission, see 
    563 U.S. at 820-23
    , simply does not
    bear on the answer to the interpretive question that we confront
    here concerning the meaning of "a controlled substance offense" in
    § 2K2.1(a)(2).
    Consider that, in reading "previous conviction[]" to
    require such a backward-looking inquiry, McNeill emphasized how
    strange it would be to treat a defendant as having been convicted
    of an offense the elements of and penalties for which would become
    known to him only upon his sentencing for his conviction of an
    entirely different offense that he had subsequently committed.
    See id. at 821 ("Although North Carolina courts actually sentenced
    contention that his 1992 breaking and entering conviction was not
    a 'serious violent felony' because that crime is now punishable by
    a maximum term of less than ten years," given that "the maximum
    term of incarceration at the time of Moss's conviction was ten
    years"); Mallett v. United States, 
    334 F.3d 491
    , 504 (6th Cir.
    2003) (deeming "implausible" an interpretation of the Guidelines
    which would require determining "the maximum term of imprisonment"
    for a "state-court conviction" "as of any time other than the date
    on which the defendant's guilt is established").
    - 17 -
    [McNeill] to 10 years in prison for his drug offenses, McNeill now
    contends that the 'maximum term of imprisonment' for those offenses
    is 30 or 38 months.           We find it 'hard to accept the proposition
    that a defendant may lawfully have been sentenced to a term of
    imprisonment       that    exceeds     the   maximum       term    of   imprisonment
    prescribed    by    law.'"     (cleaned      up)   (quoting       United   States   v.
    Rodriquez, 
    553 U.S. 377
    , 383 (2008))).                  But, there is nothing
    similarly strange about looking to federal law as it exists at the
    time of a defendant's federal sentencing to determine the criteria
    that a potentially applicable federal sentencing enhancement uses
    to determine whether the enhancement must be applied at that
    sentencing.    Indeed, ordinarily, that is precisely where we would
    look to identify those criteria.                See Bautista, 989 F.3d at 703
    ("McNeill nowhere         implies    that    the   court    must    ignore   current
    federal law and turn to a superseded version of the United States
    Code" to expound "federal sentencing law [as it] exists at the
    time of sentencing.").
    True,      a    §   922(g)   defendant's     past       criminal   conduct
    involving a substance that the CSA's drug schedules classified at
    that earlier time as "controlled" could suggest a reason to be
    concerned that the defendant is especially defiant of law and thus
    a reason to find the earlier classification of the substance by
    those schedules potentially relevant to the sentence that the
    defendant should receive for his § 922(g) conviction.                      But, that
    - 18 -
    observation   does   not   itself    support   the   conclusion   that   the
    § 2K2.1(a)(2) guideline must be read to require us to look to
    federal drug schedules not in effect at the time of the § 922(g)
    sentencing to discern the meaning of what constitutes a "controlled
    substance" and thus "a controlled substance offense" under that
    guideline as of the time of that sentencing.
    A   guideline's     enhancement      for   a   defendant's     past
    criminal conduct -- such as the enhancement that § 2K2.1(a)(2)
    imposes -- is reasonably understood to be based in no small part
    on a judgment about how problematic that past conduct is when
    viewed as of the time of the sentencing itself.             Cf. Taylor v.
    United States, 
    495 U.S. 575
    , 581-85 (1990) (noting                that the
    drafters of ACCA's enhancement intended it to capture prior crimes
    which "are inherently dangerous" and constitute "the most damaging
    crimes to society" (quotations omitted)).         There is thus reason to
    be wary of a construction of § 2K2.1(a)(2) that would require a
    judge at sentencing to apply an enhancement in consequence of the
    defendant's past conduct that itself applies only insofar as that
    past conduct involves a substance that is "controlled" without
    regard to whether the conduct in fact involved a substance that,
    so far as the CSA's drug schedules in effect at the time of that
    sentencing indicate, is "controlled."          Cf. H.R. Rep. 115-1072, at
    695 (2018) (Conf. Rep.) (describing "hemp" as an "agricultural
    crop[] having strategic and industrial importance"); cf. also 164
    - 19 -
    Cong. Rec. 4,459-60 (2018) (remarks of Sen. McConnell) ("Hemp is
    in everything from health products to home insulation" and "is a
    completely different plant from its illicit cousin. . . .                             Hemp
    will be a bright spot for our future."); 164 Cong. Rec. 4,494
    (2018) (remarks of Sen. Bennett) ("We forget, but hemp was widely
    grown in the United States throughout the mid-1800s.                          Americans
    used hemp in fabrics, wine, and paper.                       Our government treated
    industrial hemp like any other farm commodity until the early 20th
    century,     when       a   1937    law   defined       it   as   a   narcotic    drug,
    dramatically limiting its growth.                This became even worse in 1970
    when hemp became a schedule I controlled substance. . . .                             [W]e
    see   hemp   as     a   great      opportunity     to   diversify     our     farms   and
    manufacture high-margin products for the American people.").
    The reason to be wary of embracing a construction of the
    guideline that would have such a consequence is especially strong
    when one remembers that the enhancement the guideline sets forth
    is not the sole means by which a prior conviction for that conduct
    could impact the calculation of the defendant's GSR.                        For example,
    that conviction could bear on the defendant's criminal history
    score even if it does not qualify as one of an offense that is
    deemed to be a qualifying one under the enhancement set forth in
    § 2K2.1(a)(2).              See    U.S.S.G.   § 4A1.1(a)-(c);         ch.    5,   pt.    A
    (sentencing table).               And, of course, the Guidelines themselves
    are not binding on the sentencing judge, who has broad discretion
    - 20 -
    to   take    account     of     relevant     considerations     in    setting       the
    defendant's ultimate sentence.                See Rita v. United States, 
    551 U.S. 338
    , 347-51 (2007); United States v. Benoit, 
    975 F.3d 20
    , 24
    (1st Cir. 2020).
    The    government        does   also   contend   that    it    would    be
    "illogical and unfair" to subject a defendant to the enhancement
    that § 2K2.1(a)(2) sets forth simply because of the happenstance
    of the timing of his § 922(g) sentencing.               It notes in this regard
    that under a time-of-§ 922(g)-sentencing                 construction of this
    guideline, two defendants who had been convicted of the same
    offense     and    had   the    same    criminal    history   could    be    treated
    differently just because of that quirk of timing.5
    But,    this      kind     of   differential     treatment      between
    otherwise similarly situated defendants often arises when courts
    apply -- as they ordinarily must -- the Guidelines that are
    operative     at     the       time    of    sentencing.        See    
    18 U.S.C. § 3553
    (a)(4)(A)(ii) (directing courts to apply the Guidelines that
    "are in effect on the date the defendant is sentenced"); see, e.g.,
    Williams, 
    2021 WL 1149711
    , at *6 n.4 ("[T]wo similarly situated
    We note that keying the definition of "controlled substance"
    5
    to the federal drug schedules in effect at the time of the
    commission of the § 922(g) offense would create its own potential
    "disparity," as the timing of the commission of that offense might
    then be determinative of whether a defendant's prior felony
    conviction results in the enhancement, even though the underlying
    prior conviction would be the same irrespective of when the
    § 922(g) offense was committed.
    - 21 -

    if they are sentenced the day before or after the Sentencing
    Commission changes a Guidelines provision." (citing United States
    v. Horn, 
    612 F.3d 524
    , 526-27 (6th Cir. 2010))).               Indeed, the
    government conceded at oral argument that, if § 4B1.2(b) expressly
    provided that a "controlled substance" meant only "heroin or
    cocaine" at the time of a defendant's § 922(g) sentencing, that
    defendant's    prior   state   law   conviction     for   possession    of
    "marihuana" could not be deemed "a controlled substance offense"
    under § 2K2.1(a)(2) just because a no-longer-operative version of
    § 4B1.2(b) in effect at the time of that prior conviction expressly
    defined   a   "controlled   substance"    more   expansively   to   include
    either "heroin, cocaine, or marihuana."            Cf. United States v.
    Nickles, 
    249 F. Supp. 3d 1162
    , 1163-64 (N.D. Cal. 2017) (applying,
    in the course of "determin[ing] that defendant's prior conviction
    for robbery [from 2009] does not qualify as a crime of violence,"
    the "narrow[er] . . . definition of extortion" set forth in an
    August 1, 2016 amendment to the Guidelines to the benefit of a
    defendant sentenced after that date), aff'd, 
    735 F. App'x 450
     (9th
    Cir. 2018).     Yet, the very same differential treatment between
    defendants that the government suggests is "illogical and unfair"
    would occur in that event, and we fail to see a meaningful
    difference between that hypothetical guideline and this one.
    - 22 -
    C.
    The government's remaining argument relies on precedents
    that   do   not   concern    the   proper       construction     of   sentencing
    enhancements at all.         Here, the government relies chiefly on
    Mellouli v. Lynch, 
    575 U.S. 798
     (2015), in which the Supreme Court
    addressed the proper construction of a federal immigration measure
    which authorizes the removal of "[a]ny alien . . . convicted of a
    violation of . . . any law or regulation of a State, the United
    States, or a foreign country relating to a controlled substance
    (as    defined    in   section     802     of    Title   21)."        
    8 U.S.C. § 1227
    (a)(2)(B)(i) (emphasis added).
    The Court in Mellouli looked (in a manner consistent
    with McNeill) to the Kansas drug schedules from the time of the
    petitioner's      previous   Kansas      conviction      to    determine    what
    "controlled substance[s]" the "elements" of that "conviction"
    might be said to "relate to."         575 U.S. at 812-13; see id. at 802
    ("At the time of Mellouli's conviction, Kansas' schedules included
    at least nine substances not included in the federal lists"
    (emphasis added) (citing, inter alia, 
    Kan. Stat. Ann. §§ 65
    -
    4105(d), 65-4113(d)-(f) (2010 Cum. Supp.)).               But, much like in
    McNeill, the Court did not consider -- because it had no occasion
    to consider -- the issue of what temporal version of the federal
    drug schedules was relevant in determining the answer to the
    question that is analogous to the one presented here:                        what
    - 23 -
    constitutes      a     "controlled        substance"        under     
    8 U.S.C. § 1227
    (a)(2)(B)(i).           After    all,     neither    party     in    Mellouli
    contended   that     the     federal    drug    schedules      had   expanded    or
    contracted in any material way between the time of Mellouli's 2010
    Kansas conviction and his removal proceedings in 2012.
    Insofar as Mellouli may be said to touch on that issue,
    moreover, it tends, if anything, to undermine the government's
    position here.       For example, the Court in Mellouli cited to a
    footnote in the government's brief to support the conclusion that
    some of the substances on the 2010 Kansas schedules were "not
    included    in   the   federal        lists,"   575     U.S.   at    802   (citing
    Respondent's Brief at 9 n.2), and that footnote in turn relied on
    U.S. Drug Enforcement Administration documents from 2013 -- a date
    which fell after both the 2010 Kansas conviction was sustained and
    after Mellouli's removal proceedings had terminated -- to explain
    that certain substances on the 2010 Kansas drug schedules, such as
    Salvia   Divinorum     and    Jimson    Weed,    were   "not    identifiable     as
    federally controlled substances," Respondent's Brief at 8-9, 9
    n.2, Mellouli v. Lynch, 
    575 U.S. 798

    , at *8-9 & 9 n.2.          In addition, Mellouli noted that the
    actual substance involved in Mellouli's arrest, Adderall, "is a
    controlled substance under . . . federal law."                  575 U.S. at 803

    We do recognize that the Second Circuit later held in
    Doe v. Sessions, 
    886 F.3d 203
     (2d Cir. 2018), that this same
    federal immigration measure -- § 1227(a)(2)(B)(i) -- must be read
    to   make   "time-of-[prior-]conviction"   federal   drug   schedules
    relevant rather than those "in force when removal proceedings are
    initiated."   Id. at 209.   The Second Circuit reasoned that reading
    "'works to promote . . . predictability in the administration of
    immigration law,'"   id. (quoting Mellouli, 575 U.S. at 806),6
    because otherwise a previously-convicted "alien could . . . become
    removable by the time removal proceedings [are] commenced" if the
    CSA schedules after the prior conviction is sustained are "expanded
    to encompass the same drugs as [the prior conviction]," id. at
    6 In the portion of Mellouli here relied on by the Second
    Circuit, the Supreme Court explained that the categorical approach
    was   preferable   to   a  conduct-based    one  because   of   the
    "predictability" that it engenders, noting that the categorical
    approach   "enables   aliens   'to   anticipate   the   immigration
    consequences of guilty pleas in criminal court.'" 575 U.S. at 806
    (quoting Jennifer Lee Koh, The Whole Better than the Sum: A Case
    for the Categorical Approach to Determining the Immigration
    Consequences of Crime, 26 Geo. Immigr. L. J. 257, 307 (2012)); see
    also Koh, supra, at 307 ("By emphasizing statutory language and
    fixed evidentiary rules, the categorical approach permits the
    existence of 'safe harbor' pleas, which do not expose the immigrant
    to the risk of immigration sanctions."). But, the predictability
    that Mellouli was concerned with in that discussion was the
    predictability that flows from the categorical approach itself,
    see 575 U.S. at 806, and not the predictability that comes from
    interpreting a statutory definition that refers to the federal
    controlled substance lists to refer to those lists only as they
    exist at the time of any given prior conviction. Thus, it is far
    from clear that Mellouli's discussion of "predictability"
    militates in favor of the Second Circuit's construction of the
    federal immigration measure at issue in that case.

    210. Doe thus concluded that it made sense to construe the federal
    immigration measure in a manner that would provide "the alien with
    maximum clarity at the point at which it is most critical for an
    alien to assess (with aid from his defense attorney) whether
    'pending criminal charges may carry a risk of adverse immigration
    consequences.'"     Id. (quoting Padilla v. Kentucky, 
    559 U.S. 356
    ,
    369 (2010)).
    But, there is no similar concern in this context given
    both the gap in time that necessarily exists between the prior
    conviction   and    any   consequence     under   §   2K2.1(a)(2)   that    is
    attributable to it        and the      highly contingent nature of that
    consequence, as it results only if a defendant commits a new crime.
    Thus, even if we were to assume that Doe's construction of the
    federal   measure   at    issue   in    that   case   is   reconcilable   with
    Mellouli, we are not persuaded by the government's contention that
    Doe supports its position here.7
    7 The remaining lower court immigration decisions cited by
    the government do not speak -- let alone persuasively -- to the
    issue of how, temporally, to understand the criteria employed by
    § 2K2.1(a)(2) to determine whether a prior conviction is "a
    controlled substance offense."   Instead, those decisions either
    fail to present any timing issue whatsoever, see Collymore v.
    Lynch, 
    828 F.3d 139
     (2d Cir. 2016), or appear to rest largely on
    a misinterpretation of Mellouli, see Martinez v. Att'y Gen., 
    906 F.3d 281
    , 287 (3d Cir. 2018).

    D.
    In sum, hemp was not on the CSA's drug schedules when
    Abdulaziz was sentenced on account of his § 922(g) offense in
    September of 2019.   See Agriculture Improvement Act § 12619.   That
    means, given the government's timely arguments to us, that hemp
    was not a "controlled substance" within the meaning of the version
    of § 4B1.2(b) that was in effect at the time of Abdulaziz's
    sentencing and, by extension, § 2K2.1(a)(2) as of that same time.
    Accordingly, Abdulaziz's July 2014 Massachusetts conviction was
    not a conviction of "a controlled substance offense" within the
    meaning of that term as it was used in the version of § 2K2.1(a)(2)
    that was applicable at his sentencing.
    III.
    The sentence is vacated and the case is remanded for
    further proceedings consistent with this opinion.8
    8 Insofar as we hold that Abdulaziz's July 2014 Massachusetts
    conviction was not "a controlled substance offense" within the
    meaning of § 2K2.1(a)(2), the government asks that the District
    Court be allowed in the first instance to determine whether
    Abdulaziz's 2018 Massachusetts conviction for unarmed assault with
    intent to rob separately qualifies as "a crime of violence" under
    that guideline, such that the application of the enhancement might
    be justified on that basis.     The District Court at Abdulaziz's
    initial sentencing hearing observed, in line with the government's
    sentencing memorandum, that the government was "not arguing" that
    this 2018 conviction was a qualifying "crime of violence."      We
    express no opinion as to whether the question of that prior
    conviction's qualifying nature can be revisited during Abdulaziz's
    resentencing in the event the government were to ask the District
    Court to revisit it.
