On June 18, 2026, the United States Supreme Court handed down a unanimous 9-0 decision that sent ripples through the nation’s gun rights and marijuana policy debates. The high court ruled that the federal government overstepped its constitutional bounds by prosecuting a Texas man, Ali Danial Hemani, for possessing a firearm while using marijuana—a substance now legal in some form in over 40 states, but still banned federally. The decision, while narrow, marks a significant moment for millions of Americans who use cannabis and own guns, as well as for the ongoing conversation about the scope of the Second Amendment.
The case, United States v. Hemani, centered on whether federal law could bar all unlawful drug users from owning firearms, regardless of whether their drug use made them dangerous. Hemani, a dual U.S.-Pakistani citizen, admitted to using marijuana every other day but was neither intoxicated nor in physical possession of his Glock 9mm pistol when federal agents found it during a search of his home in 2022. Prosecutors charged him under a statute that makes it a crime for any “unlawful user of or addicted to any controlled substance” to have a gun—a law that carries a potential 15-year prison sentence and permanent loss of gun rights.
Justice Neil Gorsuch, writing for the court, made clear that the government’s approach was simply too broad. “We do not question that sometimes an individual’s unlawful use of marijuana (or any other controlled substance) may render him a danger to others,” Gorsuch wrote, according to ABC News. “But, again, the government disclaims the need to show anything like that in this case. ... Affording the government that kind of broad power to designate any group as dangerous and thereby disqualify its members from having a gun would risk allowing it to quickly swallow the Second Amendment.”
This ruling does not strike down the entire law. Instead, it limits federal prosecutors from targeting individuals solely for casual or occasional marijuana use. Importantly, the justices left intact other provisions: the government can still prohibit gun ownership for those who are drug addicts, currently intoxicated, or otherwise deemed dangerous. As Gorsuch put it, “We do not address efforts to ban addicts, or those presently intoxicated, from possessing a firearm.”
The case has roots in a changing national landscape. While more than 40 states now allow some form of marijuana use, cannabis remains a Schedule I controlled substance under federal law. This legal patchwork has left millions of Americans in a bind: use marijuana, even legally under state law, and risk severe federal penalties if you also own a gun. The Justice Department estimates it brings about 300 cases a year where the drug-user gun ban is the primary charge.
The Supreme Court’s decision was greeted with enthusiasm by civil liberties and gun rights groups alike. Cecillia Wang, legal director at the American Civil Liberties Union, which represented Hemani, called the ruling “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.” Wang added, “With nearly half of Americans reporting marijuana use at some point in their lives, this ruling protects the rights of millions and curbs the government’s ability to impose arbitrary and discriminatory penalties.”
John Commerford, executive director of the National Rifle Association’s Institute for Legislative Action, echoed that sentiment in a statement to ABC News: “No one should be deprived of their God-given right to keep and bear arms for engaging in nonviolent conduct, and there is no historical justification for doing so.”
The case also drew attention for its unusual coalition of supporters. The ACLU and the NRA—organizations often on opposite sides of the political spectrum—joined forces in defense of Hemani’s right to both use marijuana and own a firearm. This alliance highlighted the case’s broader implications for civil liberties and the reach of government power.
Yet, not everyone was celebrating. Gun safety advocates, including groups like the Brady Center and the Giffords Law Center, had supported the federal government’s position. They argued that the law was a “commonsense” safety measure and warned that the ruling should not be seen as a green light for all drug users to possess firearms. Leigh Rome, senior litigation attorney at Giffords, stated, “Today’s opinion continues to allow the government to enact and enforce reasonable categorical prohibitions on firearms ownership.” Kris Brown, president of Brady, added that the decision “reaffirmed the ability of legislatures to restrict firearms access by certain categories of people.”
The historical context for the law stretches back to the 1800s, when governments sometimes disarmed “habitual drunkards.” The Trump administration, despite its pro-Second Amendment rhetoric, defended the ban in court. In filings, they likened marijuana users to those earlier categories, arguing that Congress could reasonably restrict gun rights for habitual drug users. However, Gorsuch and the court found that such analogies failed to justify the blanket ban, especially as federal and state attitudes toward cannabis have shifted. “Whatever one thinks of these developments, the federal government has not just tolerated them; it helped fuel them,” Gorsuch wrote, referencing the growing acceptance and legalization of marijuana across the country.
The law at issue has also been in the national spotlight for its use in the prosecution of Hunter Biden, son of President Joe Biden. In 2024, Biden was convicted of purchasing a firearm while addicted to cocaine—a violation of the same statute. He was later pardoned by his father. The court’s ruling would not have prevented Biden’s prosecution, as he was deemed an addict at the time of his offense, a distinction the court drew clearly in its opinion.
Legal analysts noted that the Supreme Court’s approach fits with its recent trend of scrutinizing longstanding gun restrictions. In 2022, the court expanded the right to carry firearms outside the home and set a new test for evaluating gun laws: restrictions must be consistent with the nation’s historical tradition of firearms regulation. The Hemani decision applies this framework, requiring the government to show more than just drug use to justify stripping someone of their Second Amendment rights.
Looking ahead, the ruling is likely to influence ongoing debates and litigation over gun rights, drug policy, and the boundaries of federal power. Prosecutors will now need to provide evidence that a defendant’s drug use genuinely poses a danger, rather than relying on broad, categorical bans. As William Sack, a lawyer at the Second Amendment Foundation, put it, “In future cases, prosecutors would need to show more than just drug use alone and instead provide evidence that a defendant is a danger to the public as a result of consuming such illegal substances.”
For now, the Supreme Court’s message is clear: the government cannot use a wide brush to paint all marijuana users as dangerous and strip them of fundamental rights. The decision offers relief—and perhaps a bit of vindication—to the millions of Americans who have found themselves caught between evolving state laws and rigid federal statutes.
