If you hold a Florida medical marijuana card, state law does not stop you from owning a firearm, but federal law does. So the honest answer to whether you can own a firearm with a medical card in Florida is: not legally under current federal law, even though Florida itself imposes no such ban. That answer is actively being tested in court. A federal appeals court covering Florida struck the federal ban down as applied to medical marijuana patients in August 2025, and the U.S. Supreme Court is weighing a related challenge with a decision expected by summer 2026.
The Federal Rule That Creates the Problem
Marijuana is still a Schedule I controlled substance under federal law, which means the federal government recognizes no lawful medical use of it.1United States Drug Enforcement Administration. Drug Scheduling Federal statute 18 U.S.C. § 922(g)(3) makes it a crime for any “unlawful user of or addicted to any controlled substance” to possess a firearm or ammunition.2Office of the Law Revision Counsel. 18 USC 922 – Unlawful Acts Because the federal government does not recognize any lawful use of marijuana, every marijuana user is an “unlawful user” in federal eyes. The 2016 Florida constitutional amendment authorizing medical marijuana and a physician’s recommendation do not change that classification. For firearm purposes, federal law treats a Florida cardholder the same as someone buying marijuana on the street.
Florida Law Does Not Mirror the Federal Ban
Florida’s list of people barred from possessing firearms under state law covers convicted felons and certain juvenile offenders, and says nothing about controlled substance users.3Online Sunshine. Florida Statutes 790.23 – Felons and Delinquents; Possession of Firearms, Ammunition, or Electric Weapons or Devices Unlawful Having a medical card alone does not disqualify you from owning a gun under state law.
Florida’s concealed weapon license statute does mention controlled substances, but only in narrow circumstances: being found guilty of a controlled-substance crime within the past three years, being committed for substance abuse, or chronically using substances to the point of impairment.4Online Sunshine. Florida Statutes 790.06 – License to Carry Concealed Weapon or Concealed Firearm Simply holding a card, without a conviction or commitment, does not trigger those disqualifiers. The conflict between a permissive state and a prohibiting federal law is where every practical problem comes from, and under the U.S. Constitution’s Supremacy Clause, federal law wins.
What Happens When You Try to Buy a Gun
The ban shows up most visibly at the point of sale. Buying from a licensed dealer means filling out ATF Form 4473. Question 21e asks whether you are an unlawful user of or addicted to marijuana or any other controlled substance, with a printed warning that marijuana use remains illegal under federal law even in states that have legalized it. Answering “yes” blocks the sale. Answering “no” when you hold an active medical marijuana card is a federal felony: lying on the form carries up to five years in prison and a fine of up to $250,000.5Office of the Law Revision Counsel. 18 USC 924 – Penalties
The ATF has also told licensed dealers that a customer presenting a medical marijuana card gives them “reasonable cause to believe” the customer is a prohibited person. A dealer who knows about your card should refuse the sale even before you answer the question.
Private Sales Do Not Fix This
A common misconception is that buying a gun privately, where no Form 4473 is required, sidesteps the issue. It does not. Section 922(g)(3) prohibits marijuana users from possessing any firearm or ammunition, not just buying one from a dealer.2Office of the Law Revision Counsel. 18 USC 922 – Unlawful Acts A gun received through a private sale, a gift, or an inheritance still puts an active medical marijuana user in violation of federal law.
Guns You Already Own When You Get a Card
This catches many people off guard. If you already own firearms and then obtain a medical marijuana card, the federal possession ban applies immediately. There is no grace period, no formal notice from any agency, and no ATF procedure for medical marijuana patients to surrender or transfer weapons. The burden is on you to know that continued possession while using marijuana violates federal law.
The practical options are limited: transfer the firearms to someone who is not a prohibited person, store them with a licensed dealer, or stop using marijuana and let your card lapse. None are appealing, which is exactly why this issue has generated the litigation now making its way through the federal courts.
Caregivers and People Living With a Patient
If you are a registered caregiver who helps a patient obtain and use medical marijuana but do not personally consume it, the federal ban does not automatically reach you. Section 922(g)(3) applies to users, not to people who merely handle or facilitate someone else’s use. The prohibition only kicks in if actual personal use is established.
Household members fall under the same analysis. Living with a cardholder does not make you a prohibited person. The one practical concern is constructive possession: if your firearms are stored where the patient can access them, there is a theoretical risk the patient could be charged with possession. A safe only you can access reduces that exposure.
The Eleventh Circuit Ruling in August 2025
The most important recent development came on August 20, 2025, when the U.S. Court of Appeals for the Eleventh Circuit ruled that § 922(g)(3) is unconstitutional as applied to state-authorized medical marijuana users in Florida.6WUSF. Appeals Court Sides With Medical Marijuana Patients in Florida Over Gun Restriction Case The case was brought in 2022 by then-Florida Agriculture Commissioner Nikki Fried and several patients.
Applying the framework from the Supreme Court’s 2022 decision in New York State Rifle & Pistol Association v. Bruen, which requires the government to show a firearms restriction is consistent with the nation’s historical tradition of gun regulation, the appellate panel found the government failed that test. The judges noted the plaintiffs had never been convicted of any crime, had at most committed a federal misdemeanor by possessing personal-use marijuana, and could not fairly be labeled “dangerous” based solely on medical use. The court sent the case back to the district court for further proceedings.
The ruling matters, but it does not yet give Florida patients a clear green light. The case is not finally resolved, and the federal government can seek further review. The statute remains on the books and is technically enforceable while litigation continues.
What Could Change in the Next Year
Marijuana Rescheduling
The Department of Justice proposed moving marijuana from Schedule I to Schedule III in May 2024, and President Trump issued an executive order in December 2025 directing DOJ to finish the rescheduling process.7Congress.gov. Rescheduling Marijuana – Implications for Criminal and Collateral Consequences Rescheduling alone would not restore gun rights, because § 922(g)(3) applies to users of any controlled substance, not only Schedule I drugs. The DOJ told the Supreme Court in February 2026 that even after rescheduling, the gun ban should be upheld. Rescheduling would, however, weaken the argument that marijuana users are categorically dangerous.
The ATF’s New Definition of “Unlawful User”
On January 22, 2026, the ATF published an interim final rule redefining “unlawful user of or addicted to any controlled substance” for firearms purposes.8Federal Register. Revising Definition of Unlawful User of or Addicted to Controlled Substance The new rule requires proof that the person uses a controlled substance “regularly over an extended period of time continuing into the present” and expressly states that isolated or sporadic use does not qualify. For regular medical users, this likely still captures them. For someone who used marijuana a few times or stopped months ago, the new definition creates more breathing room. The comment period runs through June 30, 2026.
The Supreme Court in Hemani
In United States v. Hemani, the U.S. Supreme Court is directly considering whether § 922(g)(3) violates the Second Amendment as applied to drug users who possess firearms. During oral arguments in March 2026, several justices appeared skeptical that the government can constitutionally strip gun rights based solely on drug use. A decision is expected by summer 2026. If the Court strikes down or narrows the statute, the conflict between a Florida medical card and gun ownership could dissolve. If the Court upholds it, the Eleventh Circuit’s favorable ruling for Florida patients could be overridden.
Practical Risks Until the Law Settles
- Buying from a dealer puts you in front of Form 4473. A truthful answer blocks the sale; a false one is a federal felony carrying up to five years in prison.5Office of the Law Revision Counsel. 18 USC 924 – Penalties
- Possessing a gun while you are an active marijuana user violates § 922(g)(3) regardless of how the gun was acquired.2Office of the Law Revision Counsel. 18 USC 922 – Unlawful Acts
- Florida police generally do not enforce the federal firearms prohibition against medical marijuana patients. The real exposure comes from federal law enforcement encounters or federal charges added to other offenses.
- If a federal investigation finds marijuana and a firearm together, federal sentencing guidelines impose a four-level increase to the offense level when a firearm is found in close proximity to drugs or paraphernalia. That can add years.9United States Sentencing Commission. Primer on Firearms Offenses
The Eleventh Circuit’s ruling gives Florida patients a serious legal argument, but it has not produced a final judgment, and leaning on it as a shield while the case is still being litigated carries real risk. Anyone sitting at this intersection of a Florida medical card and firearms should talk to a Florida attorney who works in both areas. The ground is moving quickly, and the answer that is correct today may not be the answer by the end of the year.
