United States v. Hemani: Supreme Court Unanimously Strikes Down Gun Ban for Marijuana Users

In a major Second Amendment ruling issued on Thursday, June 18, 2026, the Supreme Court of the United States unanimously held that the federal government cannot criminally prosecute marijuana users for possessing firearms in their homes. The 9-0 decision in United States v. Hemani, No. 24-1234, represents a significant court reversal that curtails federal gun control enforcement and further defines the boundaries of gun ownership rights under the Court's recent constitutional jurisprudence.

Background of the Case

The case arose when federal agents searched the home of a Texas man, Hemani, who surrendered a firearm, pointed agents to marijuana on his property, and admitted that he used marijuana "every other day." The federal government prosecuted Hemani under 18 U.S.C. § 922(g)(3), a long-standing federal statute that makes it a crime for any person who is an "unlawful user of or addicted to any controlled substance" to ship, transport, possess, or receive firearms or ammunition.

Hemani moved to dismiss the indictment, arguing that the statute violated his Second Amendment rights. The federal district court granted his motion, and the U.S. Court of Appeals for the Fifth Circuit affirmed, leading the Trump administration's Department of Justice to appeal to the Supreme Court.

The Unanimous Ruling

In a 9-0 opinion written by Justice Neil Gorsuch, the Supreme Court affirmed the lower courts, holding that Hemani's prosecution under § 922(g)(3) was inconsistent with the Second Amendment.

Justice Gorsuch wrote that the statute operates as a sweeping, categorical ban that shifts an impermissible burden onto citizens:

"The statute bans a class of people from possessing essentially any firearm for any purpose, which shifts the burden to the government to show its prosecution complies with the Second Amendment.12"

To justify the restriction under the historical-analog testing framework established in New York State Rifle & Pistol Association v. Bruen (2022), the government had compared the drug user ban to historical laws disarming "habitual drunkards" or individuals who were actively intoxicated.

However, the Court rejected these comparisons. Justice Gorsuch noted that historical laws targeting "habitual drunkards" were structurally and legally distinct, targeted different populations for different reasons, and did not impose permanent, categorical bans on firearm possession inside the home for individuals who were not actively impaired.

Concurring Opinions and Legal Nuances

While the decision was unanimous, several justices penned concurring opinions to outline their specific legal views:

  • Justice Thomas filed a concurring opinion.
  • Justice Jackson, joined by Justice Sotomayor, filed a concurrence.
  • Justice Alito, joined by Justice Kagan, filed a concurrence.

The concurrers emphasized that while the federal government retains the authority to prohibit individuals from carrying or using firearms while actively under the influence of an intoxicating substance, a permanent ban on gun possession for regular users of a substance that has been widely legalized or decriminalized at the state level (such as marijuana) cannot survive constitutional scrutiny.34

Broader Implications

The ruling is a major victory for Second Amendment advocates and represents a severe blow to federal gun enforcement tools. By striking down § 922(g)(3) as applied to regular marijuana users, the decision:

  1. Undermines Federal Gun Charges: It jeopardizes thousands of open federal indictments and past convictions under the "unlawful user" provision, which has historically been one of the DOJ's most frequently used tools to disarm drug suspects.
  2. Highlights State-Federal Conflict: It highlights the growing legal chasm between federal drug laws (where marijuana remains a Schedule I controlled substance) and state-level legalization, establishing that federal drug classification cannot automatically override constitutional gun ownership rights.
  3. Defines Post-Bruen Limits: It signals that the Supreme Court's conservative majority (joined here by the liberal bloc) is unwilling to accept broad, categorical bans on gun possession unless the government can provide highly precise, direct historical analogues.

  1. An instance of No gun control measure survives if it shifts the burden of proof onto the citizen. — A unanimous Court struck down a federal ban because categorical exclusions for drug users impermissibly shifted the constitutional burden of proof. ↩︎

  2. An instance of Gun control restrictions cannot survive if they shift the legal burden of proof onto the citizen. — The Supreme Court invalidated a federal ban on firearm possession by drug users because its categorical scope shifted the constitutional burden onto gun owners. ↩︎

  3. An instance of No firearm restriction survives a judicial test stripped of direct Founding-era historical analogues. — The Supreme Court struck down the federal gun ban because the government could not offer direct, precise historical analogues to justify disarming non-intoxicated users. ↩︎

  4. An instance of No gun restriction survives a judicial test stripped of direct Founding-era historical analogues. — The Court struck down a major federal firearm ban because the government's historical analogues failed to justify a blanket, non-impairment restriction. ↩︎
