The question people are asking today is simple: Can illegal drug users own firearms under federal law?
The Supreme Court’s new unanimous decision makes the honest answer more complicated, but also clearer. The Court did not erase the federal ban on gun possession by “unlawful users” of controlled substances. What it did do is reject the government’s attempt to treat that ban as a one-size-fits-all disarmament rule for anyone who uses an illegal drug with some regularity, even when there is no allegation of addiction, intoxication while armed, threats, or violence.
Just as important, the Court framed this as an as-applied ruling focused on one defendant and one prosecution theory. The statute remains on the books, and future cases will turn on their facts and on the government’s historical justification.

The law at the center
The statute is 18 U.S.C. § 922(g)(3). It is one of several federal “prohibited person” categories that make it a felony for certain people to possess firearms.
Section 922(g)(3) covers anyone who is an “unlawful user of or addicted to” a controlled substance. And because marijuana remains a controlled substance under federal law, the statute can apply to marijuana users even in states that allow recreational or medical cannabis.
That mismatch between state legalization and federal prohibition is not a side issue. It is the legal pressure point that keeps producing high-stakes cases.
What the Court held
The case involved a Texas man, Ali Hemani, who admitted he smoked marijuana about every other day and kept a handgun at home for self-defense. Federal prosecutors charged him under § 922(g)(3).
The Supreme Court unanimously ruled that this prosecution violated the Second Amendment as applied to Hemani, given the government’s theory and the evidence it offered. Justice Neil Gorsuch wrote the Court’s opinion. Justices Samuel Alito and Elena Kagan concurred only in the judgment.
The Court stressed that its decision was narrow. It did not announce that drug users, as a category, are always protected from disarmament. And it explicitly drew a line around what it was deciding: “We do not address efforts to ban addicts, or those presently intoxicated, from possessing a firearm,” Justice Gorsuch wrote.
Why the government lost
If you have followed modern Second Amendment cases, you already know the key phrase: history and tradition.
Since New York State Rifle & Pistol Association v. Bruen (2022), the Court has required the government to justify many gun restrictions by pointing to a historical tradition of similar regulation from the relevant eras of American law. It is not enough to argue that a modern law is sensible or helpful. The government must show a historical analogue that is close enough in purpose and operation to count as part of our constitutional inheritance.
Here, the government leaned heavily on historical laws restricting firearm access for “habitual drunkards.” The Court rejected the analogy. As Justice Gorsuch put it: “The government’s analogy fails under every measure it asks us to consider.”
Gorsuch elaborated: “The historical laws on which it relies targeted different kinds of people, did so for different reasons, and operated in different ways.”
The Court’s core point was that the old laws the government invoked tended to focus on people whose substance abuse left them unable to manage their lives. By contrast, § 922(g)(3) was applied broadly to a person who used marijuana regularly but was not alleged to be addicted, intoxicated when armed, violent, threatening, or otherwise dangerous.
The Court also questioned the government’s effort to treat marijuana users as categorically dangerous, noting the federal government’s own actions in reducing marijuana enforcement and efforts to move marijuana to a less restrictive drug schedule. The Court also noted that most states now permit some form of marijuana use. “Whatever one thinks of these developments, the federal government has not just tolerated them; it helped fuel them,” Gorsuch wrote.
Finally, the Court warned against an interpretive approach that would let officials strip constitutional rights from sweeping categories of people based on a generalized claim of “dangerousness.” The opinion cautioned that affording the government “broad power to designate any group as dangerous and thereby disqualify its members from having a gun” could allow that logic to “quickly swallow” the Second Amendment.
So can marijuana users own guns
Under federal statute, marijuana users are still at risk. The federal prohibition in § 922(g)(3) has not been repealed, and marijuana remains illegal federally.
Under this Supreme Court decision, not every marijuana user can automatically be prosecuted under § 922(g)(3) simply for being a regular user. But the key point is posture: the Court held that the government’s application of the statute to Hemani, on these facts and this theory, violated the Second Amendment.
What facts are likely to matter after this ruling?
- Addiction (the Court signaled it was not deciding bans aimed at addicts).
- Present intoxication or possessing or using a firearm while under the influence.
- Threats, violence, or other individualized evidence of dangerousness.
- The timing and proof of “unlawful user” status, which has long been contested even before this case.
The uncomfortable bottom line for many readers is this: federal law still says “no,” but the Constitution now imposes tighter limits on how broadly that “no” can be enforced in at least some circumstances.
Other drugs and prescriptions
One reason the Court viewed the government’s reading as overbroad is that the statutory category is not limited to marijuana. “Unlawful user” can also capture people who misuse prescription drugs.
Justice Gorsuch highlighted how far the logic could extend. Under a broad reading, the ban could reach “a college student who routinely uses a friend’s Adderall to cram for exams” or “a husband who regularly takes his wife’s prescription Ambien to sleep.”
That matters because constitutional doctrine tends to harden around edge cases. If a legal rule would allow disarmament in scenarios the Court finds intuitively out of proportion, the Court becomes more skeptical that the rule is faithful to history, text, and constitutional structure.
Why people mention Hunter Biden
One reason this ruling exploded into public view is that it addresses the same federal provision, § 922(g)(3), that was used to prosecute Hunter Biden.
But the decision is not “about” any one defendant. It is about the government’s power to declare a status and attach a constitutional disability to it. When the government can take a right away based on a broad label, the real fight becomes: Who gets labeled, by what proof, and under what limiting principle?
Reactions
The unanimity masked meaningful differences in reasoning, and the public reactions tracked those differences in emphasis.
Carrie Severino, president of the Judicial Crisis Network, framed the outcome as a line-drawing exercise: “It’s a good day for the Second Amendment when all nine justices can agree to protect gun rights,” she said. “The mere fact of illegal drug use, without more, isn’t enough to justify prosecution for gun ownership.”
Severino also pointed to the historical distinction the Court kept returning to: “Historically, ‘habitual drunkards’ who habitually lost use of their reason could have their rights restricted, but not just regular drinkers,” even including Founding Fathers like John Adams, who drank “a tankard of hard cider” with breakfast, or James Madison, who “consumed a pint of whisky daily.”
Tyler Yzaguirre, president of the Second Amendment Institute, emphasized the methodological takeaway: “While the justices offered different legal reasoning, they unanimously agreed that applying this federal gun ban to Hemani violated the Second Amendment,” he said. “This ruling reinforces the principle that firearm restrictions must be consistent with our nation’s historical tradition of gun regulation, not modern political preferences.”
And Amy Swearer, senior legal fellow at Advancing American Freedom, argued the ruling should be read as a limiting principle, not a free-for-all: “Gun control activists will inevitably claim that the sky is falling. It isn’t,” she said. “The ruling still leaves the government room to disarm addicts or prosecute people who possess firearms while actively intoxicated.”
What to watch next
- As-applied challenges: This decision invites more defendants to argue that, on their specific facts, § 922(g)(3) is unconstitutional.
- New prosecutorial strategies: The government may focus more on intoxication, threats, or evidence of impairment to fit closer historical analogues.
- Federal cannabis policy shifts: If marijuana’s federal status changes, the statutory and constitutional landscape changes with it.
- Lower court splits: If federal courts interpret this decision differently, the Supreme Court may have to clarify again.
If you are searching for a clean rule you can memorize, the Court did not give you one. It gave something more constitutional: a limit. The government can regulate firearms, but it cannot treat the Second Amendment as a privilege that evaporates whenever an official points at a disfavored category and says “danger.”
