SCOTUS Wrestles with Guns & Marijuana in U.S. v. Hemani

Estimated reading time: 4 minutes

The Supreme Court just heard arguments in U.S. v. Hemani, and if you thought this would be a clean, predictable Second Amendment case… think again.

At the center of it all is a straightforward question with messy consequences:

Should it be a federal crime for someone who uses marijuana to possess a firearm?

Under current federal law, “unlawful users” of controlled substances are prohibited persons. Marijuana remains illegal under federal law, even if your state has legalized it. So yes, technically, someone who uses weed (even legally under state law) can lose their gun rights.

But this case isn’t just about cannabis. It’s about how far the government can go in making categorical bans on who gets to exercise a constitutional right.

Categorical Bans vs. Individual Judgments

University of Chicago law professor Darrell Miller, who filed an amicus brief in the case, argued on Fox 32 Chicago that legislatures need the ability to make broad, categorical decisions.

His example?

Even if there’s a wildly responsible, firearms-savvy seven-year-old prodigy somewhere out there, the law still says no seven-year-olds can own guns. Period.

That’s how categorical rules work.

The argument from that side is simple: drug use (especially habitual use) falls into that same category. Legislatures should be able to say, “This group can’t have guns,” without needing a case-by-case hearing for every individual.

But here’s where things get sticky.

Alcohol, Ambien… and Where Do You Draw the Line?

Josh Blackman of South Texas College of Law pointed out something the justices clearly struggled with: alcohol.

Alcohol isn’t illegal. Plenty of people drink. Some abuse it. But alcohol use alone doesn’t disqualify someone from gun ownership.

So why does marijuana?

The justices reportedly wrestled with distinctions between:

Occasional use vs. addiction
Impairment vs. moderation
Marijuana vs. heroin vs. meth
Even prescription drugs like Ambien

Justice Barrett floated a hypothetical: what if someone takes their spouse’s Ambien pill once in a while? Does that make them a prohibited person?

That’s not a minor technicality. This is a felony. If you’re considered an unlawful user and possess a gun, you’re now in felon-in-possession territory.

The Court seemed uncomfortable drawing fine lines that could ripple into dozens of other areas.

The Bruen Problem

Ever since Bruen (2022), gun laws must align with historical tradition.

So what’s the historical analog for banning drug users from owning firearms?

Back in the Founding era, there weren’t meth labs or cannabis dispensaries. But there were restrictions involving “drunkards.” That’s why that term kept popping up during arguments.

The real concern? Whatever rule the Court writes here won’t just apply to marijuana users. It could impact:

Felon prohibitions
Mental health commitments
Other categorical bans

If the Court says you can’t broadly disarm marijuana users without individualized proof of dangerousness, what happens when someone convicted of a non-violent felony from 20 years ago makes the same argument?

That’s the Pandora’s box the justices seem wary of opening.

An Unusual Coalition

Here’s another twist: this case reportedly drew support from groups you don’t typically see aligned on gun issues.

Marijuana advocates. Civil liberties groups. Gun rights supporters.

It’s not your standard red vs. blue Second Amendment fight. It’s more like constitutional consistency vs. regulatory authority.

Even with a push to reschedule marijuana federally, the Court has to rule based on the law as it existed when Mr. Hemani allegedly violated it.

And according to legal observers, don’t expect a clean 6–3 ideological split. This could be fragmented. Multiple opinions. Narrow reasoning. A ruling that resolves the case but leaves plenty unsettled.

So What Do You Think?

Should habitual marijuana users be categorically barred from owning firearms under federal law?
Or should the government have to prove actual dangerousness before stripping someone of a constitutional right?
And if the Court narrows this ban… what other gun restrictions might get challenged next?
