Last updated August 14, 2026. This article reflects the law as of that date and is for education only, not legal advice. Marijuana and firearm law is moving fast right now; talk to a Florida firearms attorney before you make a decision based on any of this.
A student pulled me aside after a Protector Level 1 class last month and asked a question I get more than almost any other now: he has a Florida medical marijuana card for a back injury, and he wanted to know if that card was going to get him arrested for owning the pistol sitting in his nightstand. I get why he asked. Between a Supreme Court ruling in June, a proposed change to the federal paperwork you sign at a gun counter, and roughly a million medical marijuana patients in this state, the honest answer is “it’s complicated, and most of what you’ve read online oversimplifies it.” Let’s walk through what actually changed and what didn’t.
The Supreme Court case everyone’s talking about
On June 18, 2026, the Supreme Court decided United States v. Hemani, a case about a Texas man named Ali Danial Hemani who was indicted under 18 U.S.C. § 922(g)(3) after federal agents searched his home and found a firearm he kept there. Hemani had told investigators he used marijuana “about every other day.” He hadn’t done anything else with the gun. No threats, no incidents, nothing beyond keeping it in his house (Congressional Research Service). The government charged him anyway, treating regular marijuana use by itself as enough to make gun possession a federal felony.
The Court disagreed, 7-2, with Justice Gorsuch writing the majority opinion joined by Chief Justice Roberts and Justices Thomas, Sotomayor, Kavanaugh, Barrett, and Jackson. Justices Alito and Kagan concurred in the judgment on narrower grounds (Supreme Court docket, No. 24-1234). The Court applied the historical-tradition test from Bruen and found that the government’s reading of Section 922(g)(3), that any regular drug use, of any substance, in any amount, automatically strips someone of Second Amendment rights, had no real historical analog. The closest the government could point to were old “habitual drunkard” laws, and the Court said those laws covered different people for different reasons through different mechanisms than what the government was doing to Hemani.
What Hemani actually decided, in plain terms
Here’s where I want to slow down, because this is the part getting mangled in a lot of the coverage I’ve seen shared in gun-owner Facebook groups. The Court called its own ruling “narrow.” It did not say marijuana users can now buy and carry guns. It did not strike down Section 922(g)(3). What it said is that the government can’t prosecute someone based solely on routine drug use, without any evidence that the person is dangerous or that the specific substance is the kind of thing that makes someone dangerous. The Court explicitly left the door open for prosecutions built on individualized facts — proof of intoxication at the time, proof the drug use led to violence, that sort of thing.
Justice Thomas, even while joining the majority, wrote separately to argue Congress never had the constitutional authority to pass this provision in the first place. Justice Jackson, joined by Sotomayor, wrote her own concurrence questioning whether the historical-tradition framework from Bruen even works well as a legal test. Those separate writings matter because they signal this issue isn’t settled at the Court — at least a few justices seem open to revisiting how these cases get analyzed going forward.
So no, Hemani did not hand medical marijuana patients a green light. What it did was take the government’s most aggressive theory of the statute off the table and leave the door open for a more limited, fact-specific version of the same law.
Why the historical-tradition test matters here
Since New York State Rifle & Pistol Association v. Bruen came down in 2022, the Supreme Court has required the government to justify modern gun restrictions by pointing to a comparable regulation from the founding era or Reconstruction, not just a policy argument about public safety. That test drove the outcome in Hemani. The government’s best historical comparison was a set of old “habitual drunkard” statutes — laws that let a town commit a chronic alcoholic, require a surety bond, or treat him as a vagrant. The Court found three real mismatches between those laws and Section 922(g)(3): the old laws targeted a narrower group of people, they served a different purpose, and they worked through different mechanisms than a blanket federal gun ban triggered by any regular drug use. Justice Alito’s concurrence, joined by Justice Kagan, would have stopped right there, deciding the case on that historical mismatch alone rather than building a broader framework the way Gorsuch’s majority opinion did. That difference matters for future cases — a narrower ruling gives lower courts less to work with when the next 922(g)(3) case comes along with different facts, like someone who uses a harder drug or who’s had a documented safety incident.
The federal form is still the real obstacle
If you walk into a gun store in Boynton Beach tomorrow to buy a firearm from a federally licensed dealer, you’re filling out ATF Form 4473. Question 21.f asks whether you’re an unlawful user of, or addicted to, marijuana or any other controlled substance, and the form spells out that this applies regardless of state medical marijuana laws. As of today, having a Florida medical marijuana card and answering “no” to that question is what several Florida attorneys have flagged as a real felony exposure problem — you’re either disqualifying yourself from the purchase by answering honestly, or exposing yourself to a false-statement charge by answering “no” while holding an active card.
There is a proposed fix moving through the regulatory process. ATF has drafted a revised version of the form that would narrow the marijuana warning to recreational use and drop the blanket reference to state-authorized medical marijuana, following the Justice Department’s move earlier this year to reschedule marijuana from Schedule I to Schedule III of the Controlled Substances Act (Marijuana Moment). That proposal is not final. It went through a public comment period and has not been adopted as the legally binding version of the form. Until ATF formally publishes a final rule and dealers start using the new form, the current form is still what governs every transaction at the counter, and so is the current legal risk. I’d treat “the form is about to change” as a headline to watch, not a decision you can rely on yet.
Where Florida law lands on this
Florida doesn’t ban firearm possession or ownership just because someone holds a medical marijuana card. Chapter 790 of the Florida Statutes, which covers weapons and firearms, doesn’t list medical marijuana patient status anywhere as a disqualifying condition. You can be a card-carrying patient under Florida’s Amendment 2 program and legally own a gun under state law alone.
The wrinkle is Florida Statute 790.06, the concealed weapon license statute. Subsection (2)(n) requires that an applicant not be “prohibited from purchasing or possessing a firearm by any other provision of Florida or federal law” (Florida Statutes § 790.06). That clause pulls federal law directly into the state licensing decision. If federal law treats you as a prohibited person because of marijuana use, that federal prohibition follows you into the CWFL application, even though Florida’s own statute never mentions marijuana. In practice, the Florida Department of Agriculture and Consumer Services isn’t cross-referencing medical marijuana registries against CWFL applications the way it checks felony records, so plenty of people hold both a card and a license without incident. That’s a gap in enforcement, not a green light in law. I’ve had more than one client assume the absence of an obvious state-level check means there’s no risk. There is; it’s just a federal risk that shows up at the gun counter, not on the CWFL application itself.
What I tell students who ask me this
I’m not going to tell a student what to do with their medical decisions, and I’m not an attorney. What I do tell them is to separate three different questions that keep getting collapsed into one: can you possess a gun you already legally own under Florida law (generally yes, if you’re not otherwise disqualified), can you truthfully complete Form 4473 to buy a new one if you’re an active medical marijuana patient (this is the genuinely hard one, and I’d get an attorney’s opinion before answering that form), and does holding a card retroactively make something you already own illegal (no, Florida law doesn’t create that trigger on its own). Conflating those three questions is how people end up either overly panicked about guns they’ve owned for years, or dangerously casual about a form they’re about to sign at a licensed dealer.
Why this keeps showing up in my Palm Beach County classes
Florida’s medical marijuana program has grown enormously since voters approved it, and Palm Beach County has a dense concentration of dispensaries and registered patients. I see students who got a card for chronic pain, anxiety, or a service-connected condition, and who also grew up around guns or serve in a profession where they’ve always carried. They’re not trying to skirt the law. They’re trying to figure out if two things they consider ordinary parts of their life — a doctor-recommended treatment and a constitutional right — are actually as incompatible as the internet makes them sound. Sometimes the honest answer is that they are, at least for now, if federal purchase forms are involved.
Renewal timing and existing CWFL holders
A separate question I get is what happens to an existing concealed weapon license if someone gets a medical marijuana card after already being licensed. Florida doesn’t run an automatic cross-check between the medical marijuana registry and the Department of Agriculture and Consumer Services’ licensing database, so a card alone doesn’t trigger a suspension or revocation notice the way a disqualifying arrest does. Your license stays valid on its normal seven-year clock. Where this can catch someone is at renewal, or if any unrelated background check puts your marijuana use in front of a federal database. That could be a new firearm purchase, an out-of-state reciprocity question, or an employment screening for a job that requires a federal check. That’s the moment the state-level silence stops protecting you, because you’re no longer dealing with Florida’s statute in isolation. I’ve heard people describe the current setup as a loophole. I’d call it closer to a gap between two systems that don’t talk to each other yet, and gaps like that tend to close eventually, not stay open forever.
What actually changes if you’re in this situation
If you already own firearms and you’re considering a medical marijuana card for a legitimate health reason, understand that federal law still treats regular marijuana use as disqualifying for purchasing new firearms, even after Hemani. That case narrowed how the government can prosecute simple possession under 922(g)(3); it did not clear medical marijuana users to buy guns at retail. If you’re already a cardholder who owns firearms and you’re wondering whether Florida is going to come knocking, the state’s own statute doesn’t create that mechanism, but I wouldn’t assume the federal side stays quiet forever either, especially if you’re ever involved in a background check for any reason.
My actual advice, every time this comes up: talk to a Florida attorney who handles firearms law before you make a decision that touches both your medical care and your gun ownership. This isn’t a place where a training instructor’s read of the news is a substitute for a lawyer who can look at your specific situation. What I can tell you with confidence is that a court ruling in June didn’t erase this problem, and a form change that hasn’t been finalized yet doesn’t help you today.
