Two of the Supreme Court's conservative justices pushed back hard against the federal government's argument that casual marijuana users can be prosecuted for owning firearms, raising pointed questions during oral arguments Monday in a case that could reshape Second Amendment law for millions of Americans.
Justice Amy Coney Barrett cut straight to the core of the government's position:
"What is the government's evidence that using marijuana a couple of times a week makes someone dangerous?"
Justice Neil Gorsuch pressed the contradiction that hangs over the entire case:
"What do we do with the fact that marijuana is sort of illegal and sort of isn't and that the federal government itself is conflicted on this?"
The case, United States v. Hemani, centers on a Texas man named Ali Danial Hemani, who argued he shouldn't face criminal charges simply because he owned a gun and smoked marijuana a few times a week. According to Newsweek, the Trump administration asked the court to revive the criminal case against Hemani under a federal law that bans all illegal drug users from owning guns. Principal Deputy Solicitor General Sarah Harris argued the law is a reasonable measure to keep firearms out of the hands of potentially dangerous people.
The court is expected to decide the case by the end of June.
This isn't really a case about one man in Texas. The ruling could determine whether the government can prosecute marijuana users for possessing a firearm, full stop. That's a question with enormous downstream consequences in a country where state after state has legalized cannabis while federal law still treats it as a controlled substance.
Gorsuch's question landed precisely on that fault line. The federal government itself cannot decide what it thinks about marijuana. States have built entire regulatory regimes and tax structures around legal cannabis. The feds, meanwhile, maintain a statute that could turn every one of those state-legal users into a felon the moment they exercise their Second Amendment rights.
Barrett's question was even more devastating to the government's position. The entire justification for stripping gun rights from marijuana users rests on the claim that they are "potentially dangerous." But Barrett demanded evidence, not assumptions. Using marijuana a couple of times a week makes someone dangerous enough to lose a constitutional right? That's a claim that requires proof, and the government apparently struggled to provide it.
Even Chief Justice John Roberts, who often charts a more cautious path, appeared uneasy with the government's argument:
"It just seems to me that this takes a fairly cavalier approach to the necessary consideration of expertise and the judgments we leave to Congress and the executive branch."
Roberts's concern is instructive. When a chief justice known for institutional deference uses the word "cavalier" to describe the government's treatment of a constitutional question, the government has a problem.
Hemani's attorney, Erin Murphy, argued that many cannabis users who regularly take gummies as sleep aids are perfectly capable of making safe decisions about firearms. It's a mundane point, and that's precisely what makes it effective. The law, as written, draws no distinction between a cartel enforcer and a suburban dad who takes an edible before bed. It treats them identically: as felons-in-waiting.
The conservative legal movement has spent decades establishing that the Second Amendment means what it says. The Supreme Court's 6-3 conservative majority has the opportunity here to reinforce a principle that should be obvious: constitutional rights require more than vague assertions of danger before the government can strip them away.
Consider the underlying logic the government is asking the court to endorse. Congress passed a law. The law says illegal drug users cannot own guns. Marijuana is federally illegal. Therefore, marijuana users cannot own guns. The syllogism is clean. The problem is that it treats a constitutional right as a technicality to be regulated away through statutory layering.
If the government can strip your Second Amendment rights because you use a substance that your own state has legalized, and that the federal government itself can't decide how to classify, then the right isn't really a right at all. It's a privilege, revocable the moment a bureaucratic category catches you in its net.
Even the ACLU, not exactly a bastion of conservative thought, recognized the stakes. Cecillia Wang, the organization's national legal director, put it bluntly:
"Anyone one of them who also owns a gun for self defense could be charged with a felony. This law violates the Second Amendment and puts far too much power in the hands of federal prosecutors, with the risk of arbitrary or discriminatory enforcement."
When the ACLU and Second Amendment advocates arrive at the same conclusion from opposite directions, it's worth paying attention to what they're converging on: prosecutorial overreach and constitutional erosion.
The court's decision, expected by the end of June, will set a marker for how seriously the judiciary takes Second Amendment protections in the post-Bruen era. The justices' questions Monday suggest that at least some members of the court are unwilling to accept "trust us, they're dangerous" as a sufficient basis for felony prosecution.
The federal government's marijuana incoherence has been a punchline for years. Now it's a constitutional crisis dressed in judicial robes. Millions of Americans live in states where cannabis is legal, regulated, and taxed. A federal law that turns those same Americans into criminals for exercising a constitutional right isn't public safety. It's a trap.
Barrett, Gorsuch, and Roberts asked the right questions Monday. The government owes the country better answers than it appears to have.
