The U.S. Supreme Court just handed down one of the most significant Second Amendment decisions in recent memory, and it matters directly to hundreds of thousands of Floridians who hold medical marijuana cards and keep a firearm at home. The case is United States v. Hemani, 608 U.S. ___ (2026), and the vote was nine to zero.
Here’s the story behind it — and it starts with a lesson about cooperation.
Medical Marijuana Card Holder and Own a Gun in Florida?
This ruling changes the legal landscape. Call John Guidry at (407) 423-1117 to understand how it applies to your specific situation before federal law catches up.
What Ali Hemani Did — and What It Cost Him
In 2022, federal agents arrived at a family home in the Dallas area to investigate terrorism-related activities. Ali Danial Hemani — a Texas-born dual citizen with a steady job — chose to cooperate fully rather than lawyer up. He handed the agents a pistol from his bedroom, directed them to marijuana on the property, sat down for a voluntary interview, and told them directly that he used marijuana about every other day. When agents found cocaine in a closet, Hemani claimed that too as his own.
The terrorism investigation went nowhere. No charges filed there. The cocaine — no charges either. Instead, more than six months later, the federal government charged Hemani with exactly one thing: possessing a firearm while being an unlawful user of marijuana, under 18 U.S.C. § 922(g)(3). For that single charge, he faced up to 15 years in federal prison and a lifetime ban on owning a firearm.
Every single piece of evidence against him came from his own mouth. He didn’t have to say any of it. His cooperation became the entire case against him.
What the Supreme Court Decided — and Why
The district court in Texas threw out the charge. The Fifth Circuit affirmed. The Supreme Court agreed unanimously on June 18, 2026, in an opinion authored by Justice Neil Gorsuch.
The legal framework comes from New York State Rifle & Pistol Association v. Bruen, 597 U.S. 1 (2022), which held that any firearm regulation must be consistent with the historical tradition of firearm regulation in early American history. The government tried to justify § 922(g)(3) by pointing to old “habitual drunkard” laws that allowed towns to jail or appoint guardians for their most incapacitated community members.
Justice Gorsuch wasn’t persuaded. A habitual drunkard in early American law wasn’t someone who drank regularly — it was someone so frequently and severely intoxicated that they couldn’t manage their own affairs, pay their debts, or care for their families. They were practically incapacitated. And then Gorsuch made the point that matters most: if regular drinking made someone a habitual drunkard, half the Founding Fathers would have disarmed themselves. John Adams reportedly had a tankard of hard cider with breakfast. James Madison put away roughly a pint of whiskey a day. George Washington drank three glasses of Madeira nightly. Days before they signed the Constitution, the framers threw Washington a farewell party where 55 guests consumed 54 bottles of Madeira, 60 bottles of wine, and considerably more alcohol. Regular intoxicant use was never the disqualifying line. Incapacitation was.
What the Ruling Does Not Do
Gorsuch was emphatic that this decision is narrow. The Court did not:
Rule that all drug users can own firearms. Strike down § 922(g)(3) entirely. Protect anyone intoxicated while possessing a gun. Protect those whose drug use demonstrates actual danger to themselves or others. Touch the existing ban on felons possessing firearms.
The government can still return with individualized proof that a specific person’s drug use makes them dangerous. The ruling simply says the government cannot automatically strip Second Amendment rights based solely on marijuana use status, with no process, no hearing, and no finding of actual danger.
What This Means for Florida Medical Marijuana Card Holders
Before this ruling, holding a valid Florida medical marijuana card and owning a firearm technically made you a prohibited person under federal law. The state of Florida permitted the marijuana use. Federal law prohibited the gun possession anyway. That contradiction sat unresolved for years.
Hemani is the first real crack in that wall. The Court ruled you cannot automatically brand someone dangerous — and strip their constitutional rights — simply because they use marijuana, without any finding that they pose a threat. For Florida’s hundreds of thousands of medical marijuana patients who own firearms, this ruling significantly changes the risk calculus. However, “significantly changes” doesn’t mean “eliminates.” Federal law still controls, the ruling is narrow, and the question of what individualized proof of danger might look like remains open.
Before assuming this ruling protects your specific situation, talk to an attorney who understands both Florida’s medical marijuana framework and federal firearms law.
The Cooperation Lesson That Lives in This Case
One more thing worth taking away from Hemani’s story, because I’ve been saying this for over 33 years and Ali Hemani is a living example of why it matters. He cooperated completely with federal agents. He volunteered his gun. He admitted his drug use. He made the government’s entire case for them in a single conversation.
His Second Amendment rights saved him. The Constitution saved him. But his cooperation nearly cost him 15 years in federal prison. Remember that the next time you feel the urge to explain yourself to law enforcement before you’ve spoken with an attorney.

John’s Takeaways
- United States v. Hemani, 608 U.S. ___ (2026), ruled 9-0 that the federal government cannot automatically strip Second Amendment rights from marijuana users under 18 U.S.C. § 922(g)(3) without proof of actual danger.
- Under Bruen, firearms regulations must match the historical tradition of early American law. The Court found “habitual drunkard” laws required actual incapacitation, not merely regular use — and the Founding Fathers themselves were regular heavy drinkers.
- The ruling is narrow. It doesn’t protect drug addicts, people intoxicated while armed, or those whose use demonstrates genuine danger. The government can still pursue individual cases with specific evidence.
- For Florida medical marijuana card holders, this is a meaningful change — but not a green light. Federal law still controls firearm possession, and courts continue to develop the full scope of the ruling.
- Hemani cooperated fully and the government tried to bury him with it. His constitutional rights saved him. Your cooperation may not receive the same outcome.
