Supreme Court unanimously rejects federal prosecution of marijuana user for gun possession

The Supreme Court ruled 9-0 that the federal government cannot prosecute a Texas man for possessing a firearm simply because he used marijuana, delivering a forceful rebuke to a decades-old provision of the Gun Control Act and expanding Second Amendment protections in the process.

Justice Neil Gorsuch wrote the majority opinion in United States v. Hemani, finding that the government failed to demonstrate its prosecution of Ali Danial Hemani squared with the Second Amendment. Every justice on the bench agreed, a unanimous verdict that left the Biden-era legal theory behind the case without a single defender on the nation's highest court.

The decision strikes at a 1968 statute that forbids unlawful drug users from having a firearm, a violation punishable by up to 15 years in prison. The government's core argument was that any regular marijuana user could be categorically stripped of gun rights without an individualized showing of danger. The Court said no.

The facts behind the case

The FBI searched Hemani's family home in Texas and found a Glock 9mm pistol, 60 grams of marijuana, and a small amount of cocaine. Federal prosecutors charged Hemani under the Gun Control Act provision barring unlawful drug users from possessing firearms.

Hemani challenged the charge on Second Amendment grounds, and the case worked its way to the Supreme Court. Oral arguments took place on March 2, 2026, with Principal Deputy Solicitor General Sarah Harris arguing for the government.

During those arguments, Gorsuch dismantled the government's historical analogy with a pointed history lesson. The government had tried to justify the modern ban by comparing marijuana users to "habitual drunkards" targeted by founding-era firearms laws. Gorsuch, as Breitbart News reported, was having none of it.

"[As for a] habitual drunkard, the American Temperance Society said back in the day, eight shots of whiskey a day only made you an occasional drunkard. We have to remember the founding era, if you want to invoke the founding era, to be a habitual drunkard you had to do double that."

Gorsuch then pointed out that the Founders themselves were hardly teetotalers. John Adams, he noted, "took a tankard of hard cider with his breakfast every day." James Madison "reportedly drank a pint of whiskey every day." He also referenced Thomas Jefferson's alcohol consumption. The implication was clear: if the government's analogy held, the men who wrote and ratified the Second Amendment might have been disarmed under their own Constitution.

The justice pressed Harris directly: "Are they all habitual drunkards who would be properly disarmed for life under your theory?"

The opinion and its reach

In the majority opinion, Gorsuch laid out the government's failure in methodical terms. The historical laws the government relied upon "targeted different kinds of people, did so for different reasons, and operated in different ways," he wrote. The analogy between founding-era habitual drunkard statutes and a modern blanket ban on gun possession by any regular user of any controlled substance simply did not hold.

"Faced with all these shortcomings in the government's submission, we cannot say it has carried its conceded burden of showing its prosecution of Mr. Hemani complies with the Second Amendment."

The word "conceded" is worth pausing on. The government itself acknowledged it bore the burden of proving the prosecution's constitutionality, and nine justices agreed it fell short.

The ruling, however, was deliberately narrow. The Washington Examiner reported that the Court declined to decide whether laws barring addicts or presently intoxicated drug users from possessing firearms are constitutional. Gorsuch left open the possibility that the government could still prosecute individuals it can prove are dangerous or currently intoxicated, but it cannot make "categorical and unfounded assumptions" about entire classes of people.

The case fits into a broader pattern at the Court. Since the landmark 2022 Second Amendment ruling that expanded gun rights and triggered a wave of legal challenges, the justices have been steadily reinforcing the individual right to bear arms against government overreach. This term alone has seen the Court grapple with several major constitutional questions testing the limits of federal power.

Thomas sounds a broader warning

Justice Clarence Thomas wrote a concurring opinion that went further than the majority. Thomas used his concurrence to warn about other outgrowths of the federal ban on gun possession by drug users that he believes need correcting. The specific concerns Thomas raised were not detailed in the opinion's coverage, but his willingness to flag additional constitutional problems signals that more challenges to federal firearms restrictions may find a receptive audience on the Court.

Thomas has been the Court's most consistent voice for an expansive reading of the Second Amendment. He has also been willing to push for broader doctrinal change in other areas, as seen when he called on the Court to end race-based redistricting after a recent Louisiana ruling. His concurrence in Hemani suggests the federal firearms code has more constitutional vulnerabilities than the government may want to acknowledge.

Strange bedfellows and sweeping implications

The case produced one of the more unusual political alignments in recent memory. AP News reported that both the ACLU and the NRA supported Hemani's case, organizations that rarely find themselves on the same side of anything.

ACLU Legal Director Cecillia Wang said the Court "sent a strong message that the government cannot criminalize the conduct of large numbers of people by making categorical and unfounded assumptions about whether they are dangerous."

Amy Swearer of Advancing American Freedom framed it in more explicitly constitutional terms: "The Court's decision today affirms one of the most basic tenets of the Second Amendment, the government may only disarm people whom it can prove are violent and unusually dangerous, based on individualized proof presented in legal proceedings."

The practical stakes are enormous. Marijuana is now legal in 24 states, and millions of Americans use it regularly. Yet under the federal statute the Court just struck down as applied, every one of those users was technically committing a felony if they also owned a firearm. That gap between state-level legalization and federal criminal liability had been growing for years, and the Court's ruling acknowledges the absurdity of the government's position.

Gorsuch himself made this point in the opinion. As Newsmax reported, the justice wrote that the federal government "has not just tolerated" the spread of legal marijuana, "it helped fuel them." That left the government "awkwardly positioned to suggest that the millions of Americans who now regularly use marijuana are categorically and unusually dangerous."

That is a devastating observation. The federal government spent years declining to enforce marijuana laws, watching states legalize the drug one by one, and collecting tax revenue from the industry, then turned around and argued that every marijuana user was so inherently dangerous they forfeited a constitutional right. Nine justices saw through it.

The Hunter Biden connection

The ruling also carries implications for one of the most politically charged criminal cases in recent years. The New York Post noted that the same federal statute was used to convict Hunter Biden, who was found guilty of purchasing a firearm while addicted to crack cocaine. The Court's decision weakens the legal foundation of that conviction, though the justices stopped short of fully striking down the statute.

The distinction matters. The Court's narrow ruling leaves room for the government to prosecute individuals who are addicted to drugs or intoxicated at the time of possession, categories that could still apply in cases like Biden's. But the broader principle is clear: the government cannot treat all drug users as presumptively dangerous and strip their rights without proof.

The Court has been operating at a remarkable pace this term, issuing decisions that reshape constitutional law across multiple domains. Chief Justice Roberts recently reminded Americans that the Court is not a political body, and rulings like Hemani, where every justice agreed regardless of ideological reputation, lend weight to that claim.

What comes next

Several questions remain unanswered. The Court did not spell out exactly where the line falls between a "regular user" who retains Second Amendment rights and an "addict" or intoxicated person who might not. That ambiguity will generate more litigation. Federal prosecutors will have to develop new theories, and new evidence, if they want to restrict gun rights for drug users going forward.

Thomas's concurrence hints that the federal firearms code contains additional provisions vulnerable to the same constitutional challenge. If the government's habitual-drunkard analogy failed here, other historical analogies propping up other restrictions may fail too. The high-stakes constitutional questions facing the Court this term are far from over.

For now, the ruling stands as a clean, unanimous affirmation of a principle that should not have required nine justices to state: the government cannot strip a constitutional right from millions of Americans based on a category, a presumption, and a historical analogy that falls apart under the slightest scrutiny.

When the men who wrote the Second Amendment were drinking pints of whiskey before lunch, maybe the federal government should think twice before calling a marijuana user too dangerous to own a gun.
