Supreme Court Strikes Down Automatic Gun Ban for Marijuana Users in Landmark Second Amendment Ruling

For more than 50 years, federal law has dictated that using any controlled substance—including marijuana—automatically strips an American of their Second Amendment right to own a firearm. On June 18, 2026, the United States Supreme Court unanimously struck down that framework.[1][4]

In a 9-0 decision in United States v. Hemani, the Court ruled that the government cannot prosecute an individual for possessing a firearm based solely on the fact that they regularly use marijuana. The ruling fundamentally alters how federal law enforcement handles the intersection of gun ownership and drug use, shifting the burden onto the government to prove a citizen is actually dangerous.[1][3][5]

The federal statute at the center of the case, 18 U.S.C. § 922(g)(3), made it a felony for anyone who is an "unlawful user of or addicted to any controlled substance" to possess a gun. Violations carried severe penalties, including up to 15 years in federal prison and a lifetime ban on firearm ownership.[3][4][7]

The law created a sprawling legal trap as states increasingly legalized medical and recreational cannabis. Because marijuana remains a controlled substance at the federal level, millions of state-legal consumers were technically committing federal felonies if they kept a gun in their homes for self-defense.[8]

The case that dismantled this provision began in Texas. In 2022, federal agents searched the family home of Ali Danial Hemani, a dual citizen of the United States and Pakistan, based on suspected terrorism-related activities involving family members.[2][7]

Hemani cooperated fully with the investigation. He surrendered a handgun he kept safely stored in his home, pointed agents to marijuana on the property, and admitted during an interview that he used the drug "about every other day."[1][7]

The terrorism investigation yielded no evidence and produced no charges against Hemani. However, more than six months later, the government indicted him on a single charge: knowingly possessing a firearm while being an unlawful user of a controlled substance. There were no allegations of violence, drug trafficking, or intoxication while handling the weapon.[3][7]

Hemani challenged the indictment, arguing that the statute violated his Second Amendment rights. After lower courts dismissed the charge, the Justice Department appealed the case to the Supreme Court, arguing that the law was necessary to disarm dangerous individuals.[2][7]

Writing for the unanimous Court, Justice Neil Gorsuch rejected the government's arguments. He applied the historical test established in the 2022 Bruen decision, which requires modern gun regulations to align with the nation's historical tradition of firearm regulation.[5]

The government attempted to compare modern drug users to "habitual drunkards" from the founding era, who were subject to certain restrictions. Gorsuch dismantled this analogy, noting that historical laws required a specific showing that a person was practically incapacitated and incapable of managing their affairs.[2][5]

Furthermore, historical laws generally provided due process—such as a probate hearing or a conviction—before an individual lost their liberties. The modern federal statute, by contrast, automatically divested an individual of their constitutional rights the moment they became an unlawful user, without any pre-deprivation process.[3][5]

Gorsuch also highlighted the inconsistency of the federal government's stance. He observed that the government has largely tolerated the state-level legalization of marijuana, making it "awkwardly positioned to suggest that the millions of Americans who now regularly use marijuana are categorically and unusually dangerous."[1]

Despite the sweeping 9-0 vote, the Court was careful to craft a narrow ruling. The decision specifically addresses the "unlawful user" provision of the statute and does not strike down the separate prohibition against individuals who are "addicted to" controlled substances.[4][5]

The ruling also does not protect individuals who handle firearms while actively intoxicated. The Court noted a clear historical distinction between disarming a sober citizen in their home and regulating the public handling of weapons by someone under the influence.[4][5]

Crucially, the decision leaves the door open for prosecutors to disarm drug users if they can provide individualized proof. If the government can demonstrate that a specific defendant's drug use renders them a danger to themselves or others, a prosecution could still survive constitutional scrutiny.[1][4][5]

The case forged an unusual alliance across the political spectrum. Gun rights organizations like the National Rifle Association filed briefs supporting Hemani, arguing against federal overreach. They were joined by civil liberties and drug policy reform groups, including the ACLU and the Cato Institute, who argued the law was a draconian relic of the war on drugs.[5][7][8]

For now, the immediate impact is clear: federal prosecutors can no longer rely on a simple admission of occasional marijuana use to secure a felony gun conviction. The burden has shifted back to the government to prove that an individual's actions, rather than their mere status as a consumer, pose a genuine threat to public safety.[3][8]
