Medical Marijuana and Gun Ownership in Florida: What the Law Says

For Florida residents who use medical marijuana and own firearms — or wish to purchase them — the intersection of state and federal law creates a serious legal conflict. Florida law permits medical marijuana use for qualifying patients, but federal law classifies cannabis as a Schedule I controlled substance and prohibits users from possessing or purchasing firearms. This article explains the current legal landscape, the specific risks patients face, and what recent court rulings mean for your rights. This is a legal summary, not legal advice — consult a qualified attorney for guidance specific to your situation.

The Federal Prohibition: 18 U.S.C. § 922(g)(3)

Under the Gun Control Act of 1968, specifically 18 U.S.C. § 922(g)(3), it is a federal crime for any person who is an "unlawful user of or addicted to any controlled substance" to ship, transport, possess, or receive firearms or ammunition. Because marijuana remains classified as a Schedule I controlled substance under the federal Controlled Substances Act — regardless of any state legalization — medical marijuana patients are considered "unlawful users" under federal law. This prohibition applies even if you hold a valid Florida medical marijuana card, even if you have never been arrested or charged with any crime, and even if you legally purchased your cannabis from a licensed Florida dispensary. The penalty for violating this statute is up to 10 years in federal prison.

ATF Form 4473: The Firearm Purchase Question

When purchasing a firearm from a licensed dealer, you must complete ATF Form 4473 — the Firearms Transaction Record. Question 21(e) asks: "Are you an unlawful user of, or addicted to, marijuana or any depressant, stimulant, narcotic drug, or any other controlled substance?" A warning printed directly on the form states: "The use or possession of marijuana remains unlawful under Federal law regardless of whether it has been legalized or decriminalized for medicinal or recreational purposes in the state where you reside." Answering "yes" will block the transaction. Answering "no" while holding an active medical marijuana card or while using cannabis constitutes a false statement on a federal form — a separate felony under 18 U.S.C. § 924(a)(1)(A), punishable by up to 10 years in prison and a $250,000 fine.

What About Firearms You Already Own?

The federal prohibition under § 922(g)(3) covers possession, not just purchase. This means that if you currently possess firearms and begin using medical marijuana, you are technically in violation of federal law by continuing to possess those firearms while being an active cannabis user. However, enforcement of this provision against individual medical marijuana patients who are otherwise law-abiding has been extremely rare. Federal prosecutors have generally focused on cases involving other criminal conduct, not on prosecuting medical patients solely for concurrent firearm possession. That said, the legal risk exists, and patients should be aware of it.

Florida State Law: No State-Level Conflict

Florida state law does not prohibit medical marijuana patients from possessing firearms. Florida Statute 790.06, which governs concealed weapons licenses, does not list medical marijuana use as a disqualifying factor. The Florida Department of Agriculture and Consumer Services, which issues concealed carry permits, does not cross-reference the state medical marijuana registry when processing applications. At the state level, there is no prohibition preventing a medical marijuana patient from owning, purchasing, or carrying firearms. The conflict exists solely between state and federal law.

The Eleventh Circuit Case: Cooper v. Garland

In a significant recent development, the U.S. Court of Appeals for the Eleventh Circuit — which covers Florida, Georgia, and Alabama — took up the case of Cooper v. Garland. Florida residents Vera Cooper and Nicole Hansell, both lawful medical marijuana patients, were blocked from purchasing firearms because answering truthfully on Form 4473 would trigger the federal prohibition. They brought a Second Amendment challenge to 18 U.S.C. § 922(g)(3) and § 922(d)(3). The Eleventh Circuit vacated the lower court's dismissal and revived the case, signaling that the constitutional challenge has merit. The court's analysis under the Supreme Court's Bruen framework — which requires the government to show historical analogues for firearms restrictions — suggests that a blanket prohibition on marijuana users may not survive constitutional scrutiny. This case is ongoing, and its outcome could reshape the legal landscape for medical marijuana patients nationwide.

Practical Considerations for Florida Patients

While the legal landscape is evolving, Florida medical marijuana patients who own or wish to purchase firearms should understand several practical realities. First, there is currently no mechanism for federal authorities to automatically access Florida's Compassionate Use Registry to check whether a gun purchaser holds a medical marijuana card. The OMMU registry is confidential under Florida law. Second, the risk of federal prosecution for a medical marijuana patient who possesses firearms without any other criminal involvement remains very low historically — but it is not zero. Third, a medical marijuana card could become relevant in other legal proceedings — for example, if you are involved in a self-defense shooting, investigators could discover your card and raise questions about your Form 4473 responses. Fourth, some patients choose to let their medical marijuana card lapse before purchasing a firearm, then reapply afterward. This is a common workaround, though its legal effectiveness is debatable since the federal statute covers current users, not just cardholders.

Federal Rescheduling: What Could Change

The DEA has been reviewing the scheduling classification of marijuana, and rescheduling from Schedule I to Schedule III has been proposed. If marijuana is rescheduled to Schedule III, it could resolve the firearms conflict — Schedule III substances like testosterone and ketamine do not trigger the same prohibitions under § 922(g)(3) when used with a valid prescription. However, rescheduling is not yet finalized, and there is no guaranteed timeline. Additionally, Congress has periodically introduced legislation — including the Second Amendment Protection Act — that would specifically exempt state-legal marijuana users from the firearms prohibition. As of early 2026, none of these bills have passed. Patients should plan based on current law, not anticipated changes.

Key Takeaways for Florida Patients

Federal law currently prohibits medical marijuana patients from purchasing or possessing firearms, regardless of Florida state law. ATF Form 4473 explicitly addresses marijuana use and warns that state legalization does not change the federal prohibition. Florida state law does not restrict firearm ownership for medical marijuana patients — the conflict is federal. The Eleventh Circuit is currently reviewing a constitutional challenge (Cooper v. Garland) that could change the legal framework. The practical risk of enforcement against individual medical patients has been historically very low but is not zero.
