Supreme Court Strikes Down Federal Ban on Gun Possession for Unlawful Users of Controlled Substances

In a unanimous decision that reshapes the intersection of federal drug policy and the Second Amendment, the Supreme Court has ruled that the government cannot automatically strip an individual of their right to possess a firearm solely because they use a controlled substance. The June 2026 ruling in United States v. Hemani struck down the categorical application of 18 U.S.C. § 922(g)(3), a decades-old federal statute that makes it a crime for any "unlawful user" of an illegal drug to own a gun. Writing for the majority, Justice Neil Gorsuch concluded that the law is unconstitutional when applied to an occasional marijuana user who is neither actively intoxicated nor individually proven to be dangerous. The decision marks a significant limitation on the government's ability to broadly designate entire classes of people as too dangerous to exercise constitutional rights without individualized due process.[1][2][3]

The case originated in Texas, centering on Ali Danial Hemani, a dual U.S.-Pakistani citizen. In 2022, federal agents searched Hemani's family home in connection with a terrorism-related investigation. While no terrorism charges were ever filed, agents discovered a 9mm Glock pistol, 60 grams of marijuana, and a small amount of cocaine. Hemani cooperated with authorities, voluntarily disclosing that he used marijuana approximately every other day. More than six months later, the government indicted him on a single count of illegal firearm possession under § 922(g)(3). Crucially, prosecutors did not allege that Hemani was intoxicated or actively using drugs at the time he possessed the firearm; the charge relied entirely on his admitted status as a regular user of a controlled substance.[1][4]

Hemani challenged the indictment, arguing that the statute violated his Second Amendment rights as applied to his specific circumstances. The U.S. District Court for the Eastern District of Texas agreed and dismissed the charge, a decision later affirmed by the Fifth Circuit Court of Appeals. The lower courts ruled that there was no historical justification for disarming a sober citizen who was not presently under an impairing influence. The Trump administration appealed the decision to the Supreme Court, urging the justices to uphold the law by arguing that habitual illegal drug users present unique dangers to society, particularly the risk of armed, hostile encounters with law enforcement.[3][4]

To defend the statute, the federal government had to satisfy the rigorous "history and tradition" test established by the Supreme Court's landmark 2022 decision in New York State Rifle & Pistol Association v. Bruen. Under the Bruen framework, the government bears the burden of proving that a modern firearm regulation is consistent with the nation's historical tradition of gun control. The Solicitor General attempted to draw a parallel between modern drug users and "habitual drunkards" from colonial-era laws, arguing that early American history supported disarming individuals who regularly used intoxicants because they were deemed unusually dangerous.[1][3][5]

That historical argument ultimately failed to persuade the Court. Justice Gorsuch systematically dismantled the government's analogy, noting that colonial-era laws targeting habitual drunkards required some form of legal proceeding—such as a probate court hearing or a justice-of-the-peace determination—before a person could be deprived of their liberty or property. Furthermore, those historical laws targeted individuals who were practically incapacitated and unable to manage their own affairs. In stark contrast, § 922(g)(3) operates as an automatic, categorical ban that strips gun rights the moment a person qualifies as an unlawful user, offering no procedural protections or individualized assessments of dangerousness.[1][5][6]

The Court also expressed deep skepticism toward the government's assertion that anyone who regularly uses a controlled substance is inherently violent. Gorsuch noted that affording the government such broad power to designate any group as dangerous would risk allowing it to "quickly swallow" the Second Amendment entirely. The majority opinion highlighted the inconsistency of the government's position, pointing out that the executive branch has simultaneously directed federal prosecutors to curtail marijuana enforcement, allowed a multi-billion dollar state-level cannabis industry to flourish, and moved to reschedule marijuana to a less restrictive drug category.[1][2][5]

Despite the unanimous outcome, the justices offered differing rationales through several concurring opinions. Justice Clarence Thomas agreed with the Second Amendment analysis but added that the statute likely exceeds Congress's authority under the Commerce Clause, arguing that regulating firearm possession solely because a gun once crossed state lines is not a genuine regulation of interstate commerce. Justices Samuel Alito and Elena Kagan concurred in the judgment only, preferring to rest the decision on the narrow ground that the government's historical analogues targeted only the truly incapacitated, without endorsing the majority's broader critique of the statute's procedural flaws and the government's regulatory choices.[1][4]

While the ruling represents a major victory for gun rights advocates and criminal defense attorneys, the Court explicitly framed the decision as a narrow one. The justices left intact the portion of the statute that prohibits firearm possession by "addicts," and they did not disturb the government's ability to disarm individuals who are actively intoxicated while armed. Furthermore, the decision does not foreclose future prosecutions under § 922(g)(3) if the government can provide individualized proof that a defendant's drug use makes them a specific threat to public safety. The ruling shifts the burden to prosecutors, who can no longer rely on a defendant's mere status as a drug user to secure a conviction.[2][5][7]

The Hemani decision is expected to have immediate and widespread implications for the federal criminal justice system. Section 922(g)(3) has long been one of the most frequently prosecuted federal gun laws, and past drug use remains a primary reason for federal background check denials during firearms transactions. Legal experts anticipate a wave of post-conviction litigation as individuals previously convicted under the categorical ban seek to have their sentences vacated or reduced. Moving forward, the ruling forces both federal prosecutors and state legislatures to adopt more narrowly tailored approaches to gun control, ensuring that restrictions are based on demonstrable danger rather than broad classifications.[2][7]
