    NIEMEYER, Circuit Judge:
    Following his conviction and sentencing for possessing two
    firearms   while       being    an    unlawful       user   of    and    addicted      to   a
    controlled substance (marijuana), in violation of 18 U.S.C. §
    922(g)(3), Benjamin Carter appealed, contending that § 922(g)(3)
    infringed on his right to bear arms, in violation of the Second
    Amendment.      We vacated the judgment and remanded the case to the
    district court to allow the government to substantiate the fit
    between § 922(g)(3) and the government’s important interest in
    protecting the community from gun violence.                        See United States
    v. Carter (“Carter I”), 
    669 F.3d 411
    (4th Cir. 2012).                                  After
    taking evidence from both sides, the district court held that
    the   government        had    carried        its    burden       in    justifying       the
    regulation   of    guns       under    §     922(g)(3),     and    Carter      filed    this
    second appeal.
    Because     we     agree        with     the    district         court    that    the
    government adequately demonstrated a reasonable fit between its
    important interest in protecting the community from gun violence
    and § 922(g)(3), which disarms unlawful drug users and addicts,
    we now affirm.
    I
    In Carter I, we recited the facts:
    Responding to complaints of suspected drug activity at
    735 Central Avenue, Charleston, West Virginia, a two-
    2
    unit apartment building where Carter was living at the
    time, Charleston police investigated by knocking on
    doors and talking with persons who answered.     After
    finding evidence of marijuana use in the first unit,
    the officers proceeded to knock on Carter’s door.
    Carter answered and allowed the officers to enter his
    apartment.    Upon smelling marijuana, the officers
    questioned Carter, who acknowledged that he had been
    smoking marijuana and indeed that he had been using
    the drug for 15 years.    The officers recovered from
    the apartment 12 grams of loose marijuana, 15 grams of
    partially smoked blunts, a digital scale, $1,000 in
    larger bills, and $122 in smaller denominations.
    Carter also informed the officers about two firearms
    in his closet -- a semi-automatic pistol and a
    revolver -- and disclosed that he had purchased the
    weapons from a friend a week earlier for his defense.
    He later explained in more detail that he had
    purchased the guns because he lived in “a bad
    neighborhood” and needed weapons to protect himself
    and his nephew, who also lived with him in the
    apartment.   Indeed, at sentencing, Carter’s attorney
    represented to the court that one month after Carter’s
    arrest in this case, the other unit in the apartment
    building was burglarized, and his neighbor was shot
    eight times.
    Carter 
    I, 669 F.3d at 413
    .
    After      Carter   was    indicted   for     violating      18   U.S.C.   §
    922(g)(3), he filed a motion to dismiss the indictment, arguing
    that the statute violated his Second Amendment rights.                   When the
    district court denied his motion, Carter entered a conditional
    guilty   plea    that    preserved   his   right    to   appeal    the    court’s
    ruling on the motion.          After accepting Carter’s guilty plea, the
    court sentenced Carter to three years’ probation.
    On appeal, we vacated the judgment and remanded the case to
    the district court for further consideration of Carter’s Second
    3
    Amendment    challenge.       We   assumed    that   Carter’s   circumstances
    implicated the Second Amendment but held that, because he could
    not claim to be a law-abiding citizen, any infringement of his
    right to bear arms would not have implicated a “core” Second
    Amendment right.       Carter 
    I, 669 F.3d at 416
    ; see also District
    of Columbia v. Heller, 
    554 U.S. 570
    , 635 (2008).                We therefore
    applied    intermediate      scrutiny    to   review   Carter’s   challenge.
    Carter 
    I, 669 F.3d at 417
    .              Under intermediate scrutiny, the
    question    thus    became    whether    there   was   “a   reasonable   fit”
    between § 922(g)(3) and “a substantial [or important] government
    objective.”        
    Id. (quoting United
    States v. Chester, 
    628 F.3d 673
    , 683 (4th Cir. 2010)) (internal quotation marks omitted).
    We readily concluded that the government had advanced an
    important governmental interest in protecting the community from
    crime and, in particular, from gun violence.             Carter 
    I, 669 F.3d at 417
    .     On whether disarming drug users and addicts through §
    922(g)(3) reasonably served that interest -- whether there was
    “a reasonable fit between the important goal of reducing gun
    violence and the prohibition in § 922(g)(3)” -- we noted that
    the government could “resort to a wide range of sources, such as
    legislative text and history, empirical evidence, case law, and
    common sense, as circumstances and context require[d].”               
    Id. at 418.
         We found that while the government had made plausible
    commonsense arguments about the risks of mixing drugs and guns,
    4
    it had “presented no empirical evidence or data to substantiate
    them.”      
    Id. at 419-20.
                Therefore, in light of Chester and
    United     States   v.    Staten,      
    666 F.3d 154
        (4th   Cir.      2011),   we
    remanded the case to the district court to “allow the government
    to develop a record sufficient to justify its argument that drug
    users and addicts possessing firearms are sufficiently dangerous
    to require disarming them.”             Carter 
    I, 669 F.3d at 419
    .
    On    remand,      both   the    government         and     Carter      submitted    a
    number of publications and studies to the district court about
    the behavioral tendencies of drug users.                        After considering the
    evidence, the court concluded that the government had carried
    its   burden,   finding         that   the       data    indicated       “a   correlation
    between violent crime . . . and drug use.”                             While the court
    acknowledged    that      the    government’s           studies    did     not    prove   “a
    strict causal nexus” between drug usage and violence, it found
    that “the two factors frequently coincide.”                            In addition, it
    pointed to “common-sense notions” that supported the fit between
    drug users and violence, noting (1) that drug users are more
    likely to encounter law enforcement; (2) that their criminal
    associations increase the risk of violence; (3) that the high
    price of drugs is likely to lead to violent property crimes; and
    (4) that drug use impairs judgment.                 The court then concluded:
    Based upon the narrowed design of the statute, the
    empirical and scholarly evidence relied upon, the
    weight of precedent nationwide, and common sense, the
    5
    United   States    has   shouldered   its  burden   of
    establishing that section 922(g)(3) is reasonably
    fitted   to   achieve  the    substantial governmental
    objective of protecting the community from crime by
    keeping guns out of the hands of those impaired by
    their use of controlled substances.        The court,
    accordingly, concludes that section 922(g)(3) is
    constitutional as applied to Mr. Carter.
    From the district court’s judgment on remand, Carter filed
    this second appeal.
    II
    Carter     contends     that,   on       remand,      the   government    still
    failed    to    prove    that    a   regulation            disarming    drug   users
    reasonably      serves     the   important          governmental       interest   of
    protecting the community from gun violence. 1
    The government was required to show that the fit between §
    922(g)(3) and the government’s important goal is “reasonable,
    not perfect.”       Carter 
    I, 669 F.3d at 417
    (quoting United States
    v. Marzzarella, 
    614 F.3d 85
    , 98 (3d Cir. 2010)).                         It was not
    required to prove that “the regulation is the ‘least intrusive
    means of achieving the relevant government objective, or that
    there    be    no   burden   whatsoever        on    the    individual    right   in
    1
    Carter also presents arguments in his brief that we
    previously resolved in Carter I, presumably to preserve them for
    further review.   He again argues that we should employ strict
    scrutiny in reviewing his claim that § 922(g)(3) infringes on
    his Second Amendment rights; that § 922(g)(3) is overly broad;
    and that § 922(g)(3) is underinclusive. Because we disposed of
    these issues in Carter I, we discuss them no further in this
    opinion. See Carter 
    I, 669 F.3d at 416
    -17, 420-21.

    question.’”       
    Staten, 666 F.3d at 159
    (quoting United States v.
    Masciandaro, 
    638 F.3d 458
    , 474 (4th Cir. 2011)).                          Moreover, its
    burden in this case was lower than in other § 922(g) Second
    Amendment     cases    because     of    §       922(g)(3)’s       “limited      temporal
    reach” -- i.e., the fact that § 922(g)(3)’s prohibition lasts
    only as long as the individual remains an unlawful drug user or
    addict.     Carter 
    I, 669 F.3d at 419
    .
    Carter argues that the district court, in concluding that
    the government carried its burden, erred in two respects:                              (1)
    it improperly relied on factors other than empirical evidence in
    evaluating the soundness of § 922(g)(3); and (2) it failed to
    recognize     that    the   studies     submitted         by    the    government     were
    inadequate because they related to drug use generally rather
    than   marijuana      use   specifically           and   they    failed    to    prove    a
    causal link between marijuana use and violence.                           He maintains
    that    the   studies       he   submitted         demonstrate        that,     in   fact,
    “marijuana users are not prone to violent behavior.”                            (Emphasis
    added).     We address these points seriatim.
    A
    On   the   scope     of   the    district         court’s      consideration      on
    remand,     Carter    contends    that       the    court      improperly     relied     on
    factors other than empirical evidence in evaluating the validity
    of § 922(g)(3).         He asserts that in Carter I, we rejected the
    7
    government’s      use        of    non-evidentiary              support,     such    as     its
    reliance     on   common      sense,        and     that    therefore       the   court     was
    required to consider only evidence “presented in the crucible of
    an    adversary     proceeding.”               While       he    acknowledges       that    the
    district     court     did        in    fact    receive         empirical    studies       into
    evidence,    he   notes       that       its   determination         “included       a    heavy
    reliance on other factors,” such as the “design of the statute,”
    the    “weight    of       precedent        nationwide,”          and    “common      sense.”
    Without these other factors, he argues, the government’s showing
    was insufficient.
    Carter’s argument misreads our prior opinion in this case.
    In Carter I, we held that, in establishing the “fit between a
    regulation    and      a    governmental          interest,”       the     government      “may
    resort to a wide range of sources, such as legislative text and
    history,     empirical        evidence,           case     law,    and     common     sense.”
    Carter 
    I, 669 F.3d at 418
    (emphasis added).                              While it is true
    that we found the government’s commonsense arguments, standing
    alone, insufficient to justify § 922(g)(3), that did not imply
    that legislative text and history, case law, and common sense
    could play no role in justifying Congress’s enactment.                                   To the
    contrary, we noted that the government’s commonsense arguments
    in    this    case         were        plausible     and        therefore     supported       §
    922(g)(3)’s constitutionality, observing that the government’s
    remaining burden “should not be difficult to satisfy.”                                   
    Id. at 8
    419.     In short, our holding in Carter I clearly did not preclude
    the district court from considering factors other than empirical
    evidence,       and,     as    such,   the      district       court       did   not       err    in
    upholding § 922(g)(3) by relying on “the narrowed design of the
    statute,       the    empirical       and    scholarly        evidence[,]         .    .    .    the
    weight of precedent nationwide, and common sense.”
    B
    Focusing on the substance of the studies presented by the
    government to the district court, Carter contends that the data
    were    inadequate          because    they     related       to     drug    use       generally
    rather than marijuana use specifically and because they failed
    to     prove    a     causal      relationship            between    marijuana         use       and
    violence.           He   maintains       that       the    studies     he    submitted,           by
    contrast, demonstrated that “marijuana users are not prone to
    violent behavior.”            (Emphasis added).
    We      have      little    trouble          concluding       that        the       studies
    presented       to    the     district      court     by     both    the    government           and
    Carter indicate a strong link between drug use and violence.                                       A
    study by Carrie Oser and colleagues, offered by the government,
    found that probationers who had perpetrated violence in the past
    were significantly more likely to have used a host of drugs --
    marijuana,          hallucinogens,          sedatives,         and     heroin          --       than
    9
    probationers who had never been involved in a violent episode. 2
    A   2004     survey      of   prisoners    by       the    Bureau    of    Justice,    again
    offered by the government, found that almost 50% of all state
    and federal prisoners who had committed violent felonies were
    drug abusers or addicts in the year before their arrest, as
    compared to only 2% of the general population. 3                          That survey also
    found that inmates who were dependent on drugs or abusing them
    were       much   more    likely     to    have       a    criminal       history. 4     The
    government also presented a study by Lana Harrison and Joseph
    Gfroerer, which found that individuals who used marijuana or
    marijuana         and     cocaine,        in        addition        to     alcohol,     were
    significantly         more     likely     to    engage       in     violent    crime   than
    individuals who only used alcohol. 5                      And finally, the government
    presented a study by Virginia McCoy and colleagues, which found

    that   chronic      cocaine   and    opiate       users       were    more    likely   than
    nonusers to engage in robbery and violence. 6
    Carter seeks to marginalize these studies, arguing first
    that they are too broad and discuss only “general categories of
    offenders,     including      those       who    abuse     a    range    of    controlled
    substances.”        He contends that, even if there is a link between
    “harder” controlled         substances          and   violence,       the    government’s
    evidence does not indicate that marijuana users are prone to
    violence.       To   the   contrary,       he     claims       that    the    evidence    he
    submitted      disproves      such    a     link.         Yet,        even    if   such   a
    particularized demonstration is necessary -- an issue we need
    not    reach   --    the   studies    presented          by    the    government       amply
    demonstrate a connection between marijuana use specifically and
    violence.      The Harrison and Gfroerer study, for instance, found
    that, “[e]ven after controlling for other variables[,] such as
    age, race, income, education, and marital status, . . . using
    marijuana in the past year . . . [was] significantly related to
    criminal behavior.” 7          Also, the study by Oser and colleagues

    The study used logistic regression and found that individuals
    who used marijuana in the past year were more than twice as
    11
    found       that,    among       probationers,       individuals      who        had   been
    involved in violence were more likely to have used marijuana. 8
    Finally, the 2005 National Survey on Drug Use and Health found
    that       individuals    arrested       for    a   serious    violent      or    property
    offense       in    the   last    year    were      much    more   likely    than      non-
    arrestees to have used marijuana. 9
    Moreover, the evidence that Carter offered to refute the
    link between marijuana use and violence -- a study by Evelyn Wei
    and colleagues 10 -- actually provides additional evidence that
    marijuana use and violence coincide. 11                    The Wei study tracked the
    likely to report both committing and being booked for violent
    crimes.

    Crimes (2005).     This survey found that 46.5% of individuals
    arrested for a violent offense (murder, rape, robbery, or
    aggravated assault) or a property offense (burglary, theft,
    motor vehicle theft, or arson) had used marijuana in the past
    year, compared to 10.0% of those not arrested for any serious
    offense.

    Carter also presented a 2003 “West Virginia Drug Threat

    use and violence based on its statement that “[m]arijuana

    years and found that, “at age 18, frequent marijuana users were
    11 times more likely than nonfrequent users to . . . engage in
    violence.” 12   The study also found that marijuana use in one year
    frequently predicted violence in the subsequent year. 13              Carter
    argues nonetheless that the Wei study militates in his favor
    because, when it controlled for “risk factors,” the correlation
    between    marijuana   use   in   adolescence   and   violence   in    young
    adulthood was not statistically significant. 14        In this instance,
    we do not think that the Wei study’s failure to identify a
    to protect their product and turf; however, marijuana abusers
    rarely commit violent crimes.”      National Drug Intelligence
    Center, U.S. Department of Justice, West Virginia Drug Threat
    Assessment 13 (2003). This conclusory statement, however, lacks
    any empirical or even anecdotal support, and therefore we accord
    it no weight.

    14
    Wei et al., Teasing Apart, at 177-178 & tbl.3. To provide
    a bit more detail: Wei and colleagues used logistic regression
    to measure whether marijuana use in adolescents aged 11 to 14
    was correlated with their engaging in violence when they were
    aged 15 to 20. To isolate the effect of marijuana use, Wei and
    colleagues controlled for various “risk factors”: self-reported
    property crime, low academic achievement, poor communication
    with caretaker, caretaker perception of bad neighborhood,
    African-American  ethnicity,   and   hard  drug   use.     After
    controlling for those variables, they found that adolescents who
    used marijuana were still 1.91 times more likely to engage in
    violence later in young adulthood. However, Wei and colleagues
    called this relationship “spurious” because the p-value was only
    0.068. 
    Id. at 178.
    13
    statistically significant correlation is particularly relevant. 15
    Indeed, we        note that the study, even when controlling for risk
    factors, still found that adolescents who used marijuana were
    almost twice as likely to engage in violence when they became
    young adults.         Thus, the Wei study, far from undercutting the
    government’s position, provides it with strong support.
    Carter also objects to the government’s evidence on the
    grounds that it demonstrated, at most, a correlation between
    marijuana     use     and    violence        and      not     a    causal    relationship.
    Quoting     the     Wei     study,      he   argues         that    “[t]he    relationship
    between   marijuana         use   and    violence       ‘is       due   to   the   selection
    effects   whereby         these   behaviors          tend    to    co-occur    in    certain
    individuals,        not     because      one        behavior       causes    the    other.’”
    (Emphasis added) (quoting Wei et al., Teasing Apart, at 166).
    This     argument       is    flawed,          however,       because    it    assumes,
    incorrectly,        that      Congress          may     not        regulate        based   on
    correlational evidence.              We conclude that it may and that the
    15
    First, we think it rather irrelevant to § 922(g)(3) --
    which concerns active unlawful drug users -- whether marijuana
    use among adolescents predicts violence years later.     Second,
    one of Wei’s “risk factors” was hard drug use.      But Congress
    would be well within its rights in disarming marijuana users if
    such users were more likely to engage in violence because of
    their hard drug use.    Controlling for hard drug use improperly
    weakened the correlation. Third, and most critically, a p-value
    of 0.068 indicates that there was only a 6.8% chance that the
    correlation was due to chance.      Scientists may insist on p-
    values of 0.05, but Congress is not so constrained.
    14
    government need not prove a causal link between drug use and
    violence    in   order    to    carry    its      burden    of   demonstrating        that
    there is a reasonable fit between § 922(g)(3) and an important
    government objective.          See 
    Staten, 666 F.3d at 164-67
    (upholding
    § 922(g)(9)’s disarmament of those convicted of a misdemeanor of
    domestic violence in large part based on correlational evidence
    about recidivism rates).              Indeed, the studies put forward by
    both Carter and the government in this case illustrate just how
    powerful      correlational      evidence         can    be.      The    Harrison      and
    Gfroerer study and the Wei study both used logistic regression
    to   show   that   individuals        who    used       marijuana    were    much     more
    likely   to     engage   in    violence,         even   controlling      for   multiple
    demographic      and     behavioral      variables         including        age,    race,
    economic status, marital status, and educational level.                             While
    eliminating      these   potentially         confounding         variables     does    not
    prove    that    marijuana      use     causes      violence,       it   substantially
    bolsters the link and helps to justify regulating gun possession
    by marijuana users.           We have emphasized that, under intermediate
    scrutiny, the fit between the regulation and the harm need only
    be reasonable, not perfect.               Carter 
    I, 669 F.3d at 417
    .                   The
    correlational evidence put forward by the parties in the present
    case easily clears that bar.
    While the empirical data alone are sufficient to justify
    the constitutionality of § 922(g)(3), we find that common sense
    15
    provides       further        support.          In        Carter     I,    we      noted     the
    government’s argument that “due to the illegal nature of their
    activities, drug users and addicts would be more likely than
    other       citizens    to    have      hostile      run-ins       with    law   enforcement
    officers, which would threaten the safety of the law enforcement
    officers       when    guns       are     
    involved.” 669 F.3d at 419
    .     The
    government also warned that “the inflated price of illegal drugs
    on    the    black     market      could     drive    many    addicts       into    financial
    desperation, with the common result that the addict would be
    ‘forced to obtain the wherewithal with which to purchase drugs
    through criminal acts either against the person or property of
    another or through acts of vice such as prostitution or sale of
    narcotics.’” 16        
    Id. Finally, the
    government suggested that drugs
    “impair [users’] mental function . . . and thus subject others
    (and    themselves)          to    irrational       and    unpredictable         behavior.” 17

    This hypothesis finds support in the evidence submitted
    by the government, which indicates that approximately 18% of
    federal and state prisoners committed their crimes in order to
    obtain money for drugs. BJS Survey, at 6. This figure rises to
    30% for state prisoners arrested for property offenses. 
    Id. 17 This
    suggestion was also borne out by the government’s
    evidence, which reports that 32% and 26% of state and federal
    prisoners, respectively, were using drugs at the time of their
    offense. BJS survey, at 5.

    have difficulty exercising self-control, particularly when they
    are under the influence of controlled substances”).                   We find all
    three of these observations convincing, and Carter has provided
    no argument grounded in either logic or evidence to undercut
    them.
    Finally, we observe that every court to have considered the
    issue has affirmed the constitutionality of § 922(g)(3) under
    the Second Amendment.        See, e.g., 
    Dugan, 657 F.3d at 999
    ; United
    States    v.   Yancey,     
    621 F.3d 681
    ,   682     (7th   Cir.    2010)     (per
    curiam); United States v. Seay, 
    620 F.3d 919
    , 925 (8th Cir.
    2010); United States v. Richard, 350 F. App’x 252, 260 (10th
    Cir. 2009).       Indeed, the majority of these courts found the
    statute constitutional without relying on any empirical studies.
    See 
    Dugan, 657 F.3d at 999
    ; 
    Seay, 620 F.3d at 925

    F. App’x at 260.
    At    bottom,   we    conclude     that   the    empirical      evidence    and
    common sense support the government’s contention that drug use,
    including      marijuana   use,   frequently       coincides     with   violence.
    Carter has failed to present any convincing evidence that would
    call this conclusion into question.                Accordingly, we join our
    sister    circuits    in    holding     that   §     922(g)(3)    proportionally
    advances    the   government’s     legitimate        goal   of   preventing     gun
    17
    violence     and   is   therefore   constitutional   under   the   Second
    Amendment.    The judgment of the district court is
    AFFIRMED.
