Can You Own a Gun With a Medical Marijuana Card? (2026)

What Medical Marijuana Patients Need to Know About Firearms

Federal law prohibits firearm possession by medical marijuana patients under 18 U.S.C. section 922(g)(3), the controlled-substance provision of the Gun Control Act of 1968. The Department of Justice's April 22, 2026 administrative order moving state-licensed medical marijuana from Schedule I to Schedule III of the Controlled Substances Act did not repeal that prohibition. State permitless concealed-carry laws like Florida HB 543 and Texas HB 1927 did not repeal it. The Supreme Court's June 18, 2026 decision in United States v. Hemani rejected one prosecution based solely on regular marijuana use, but it did not strike down the statute, and the Form 4473 attestation still applies at every Federal Firearms Licensee gun counter in the United States.

Miracle Leaf® physicians evaluate qualifying conditions and certify patients into state medical marijuana registries. Miracle Leaf® cannot provide legal advice on the intersection of medical certification and federal firearms law. This post explains the federal framework, the post-Bruen litigation reshaping it, the Florida and Texas state-licensing posture, and the practical risk tiers for purchasing, possessing, and carrying. Every patient considering a firearm purchase or possession decision while holding an active medical card should consult a Second Amendment attorney licensed in their state.

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

The Gun Control Act of 1968 makes it a federal felony for any person who is an unlawful user of, or addicted to, any controlled substance to ship, transport, receive, or possess any firearm or ammunition in interstate or foreign commerce. The statute does not define unlawful user and contains no temporal nexus specifying how recently a substance must have been consumed to trigger disarmament. Historically the ATF interpreted the phrase broadly, treating a single failed drug test, a misdemeanor possession conviction, or possession of a state medical marijuana card as sufficient to establish prohibited-person status.

Federal prosecutors have brought section 922(g)(3) charges against non-violent cannabis users. The Jared Harrison prosecution in Oklahoma began with a routine traffic stop and produced a federal indictment carrying up to 15 years for possessing a firearm alongside marijuana products. The Paola Connelly prosecution proceeded after a shots-fired call at her home revealed cannabis (her husband had fired the shots). The Hunter Biden prosecution applied the same statute. The statutory penalty under the Bipartisan Safer Communities Act framework runs up to 15 years and a $250,000 fine for false statements on the firearms transaction record.

ATF Form 4473 Question 21.g and the False-Statement Felony

Every commercial firearm purchase from a federally licensed dealer requires the buyer to complete ATF Form 4473, the Firearms Transaction Record, under penalty of perjury. The current controlled-substance question (now Q21.g, historically Q11.e then Q21.e then Q21.f as the form has been revised) asks whether the buyer is an unlawful user of, or addicted to, marijuana or any other controlled substance. A bolded warning added in 2017 states that marijuana use remains unlawful under federal law regardless of state legalization.

Answering Yes produces an automatic transfer denial with no criminal liability. Answering No while holding an active medical card or actively consuming exposes the buyer to two federal felony statutes: 18 U.S.C. section 922(a)(6) (false statement material to lawfulness of sale) and 18 U.S.C. section 924(a)(1)(A) (false statement in records required to be kept by an FFL). The Supreme Court held in Abramski v. United States, 573 U.S. 169 (2014), that Form 4473 attestations are material to the lawfulness of the sale.

The signed form is the evidence. Conviction rates on prosecuted Form 4473 cases approach certainty because the document is documentary proof of the offense.

The 2026 ATF Interim Final Rule and Form 4473 Revision

Two administrative shifts in 2026 have softened, but not eliminated, the federal prohibition.

The January 2026 ATF Interim Final Rule narrowed the definition of unlawful user. Under the new rule a person qualifies as an unlawful user only if they regularly use a controlled substance over an extended period of time continuing into the present, with sufficient regularity and recency to indicate active engagement. Isolated or sporadic use no longer triggers the prohibition. The rule still likely captures habitual medical patients who consume daily or weekly to manage chronic conditions.

In response to the April 22 2026 rescheduling, the ATF proposed a revised Form 4473 with a public comment period that closed August 6, 2026 (Federal Register doc. 2026-09182). The proposed text states: "I am not an unlawful user of, or addicted to, marijuana or any depressant, stimulant, narcotic drug, or any other controlled substance. (Warning: You can be an unlawful user under federal law, even if your possession is legal under state law. Federal law does not permit the use or possession of marijuana for recreational purposes.)" The previous explicit reference to medicinal use was removed. Legal analysts read the draft as narrowing the federal prohibition to recreational use, but the form is not yet finalized and the underlying statute is not yet amended.

Post-Bruen: How the Courts Are Unwinding the Categorical Ban

The Supreme Court's 2022 decision in New York State Rifle & Pistol Association v. Bruen, 597 U.S. 1, replaced the previous means-end scrutiny test with a strict historical-tradition standard. Under Bruen, if the Second Amendment's plain text covers an individual's conduct, the government must prove the regulation is consistent with the Nation's historical tradition of firearm regulation. Founding-era analogues are required.

The Fifth Circuit applied Bruen to section 922(g)(3) in United States v. Daniels, 77 F.4th 337 (5th Cir. 2023), and reversed the conviction of a regular marijuana user found with firearms during a traffic stop. The court held that while historical traditions may support disarming an actively intoxicated person, no founding-era analogue supports disarming a sober citizen based on past or habitual drug use. The decision binds federal courts in Texas, Louisiana, and Mississippi.

In Florida, Florida Commissioner of Agriculture v. Attorney General (11th Cir. Aug. 20, 2025) (formerly Fried v. Garland) revived the civil rights claims of state-compliant medical marijuana patients seeking to invalidate section 922(g)(3) as applied. The Eleventh Circuit panel held the federal government failed at the pleading stage to satisfy the Bruen historical burden. The case returns to the district court for evidentiary review.

The Supreme Court decided United States v. Hemani, No. 24-1234, on June 18, 2026, after oral argument on March 2, 2026. Justice Gorsuch wrote for the Court and affirmed the Fifth Circuit's dismissal of the indictment. Ali Hemani was prosecuted under section 922(g)(3) solely because he admitted using marijuana about every other day. The Court rejected the government's analogy to historical habitual-drunkard laws, which targeted people incapacitated by drink and usually required some legal process first. In the Court's words, "we cannot say it has carried its conceded burden of showing its prosecution of Mr. Hemani complies with the Second Amendment." The Court also noted that the Department of Justice had curtailed enforcement against marijuana users and had moved some marijuana products to Schedule III.

The Court described its decision as narrow. It did not strike down section 922(g)(3). It did not address bans on addicts or people who are presently intoxicated, other laws Congress might write for specific drugs, or prosecutions backed by individualized proof that a person's drug use makes them a danger to themselves or others. Justice Thomas and Justice Jackson (joined by Justice Sotomayor) wrote concurrences, and Justice Alito (joined by Justice Kagan) concurred in the judgment. The ruling does not change the Form 4473 question or the federal false-statement statutes. How Hemani applies to any individual patient is a question for a Second Amendment attorney.

Florida CWFL, HB 543 Permitless Carry, and the MMUR Privacy Shield

The Florida Department of Agriculture and Consumer Services administers the Concealed Weapon or Firearm License and has publicly stated it does not query the Medical Marijuana Use Registry during licensing. The MMUR is confidential and exempt from public record under Florida Statute section 381.987. Law enforcement access is limited to active investigations where the subject specifically claims a medical marijuana exception.

Florida HB 543, effective July 1, 2023, eliminated the CWFL requirement for eligible adults age 21 and older. Patients no longer need to submit a state application or answer state questions about drug use. The eligibility prohibitions in Florida Statute section 790.06 still apply (felony conviction, certain domestic violence or mental health adjudications).

HB 543 did not change federal law. A patient may carry a previously owned firearm under state law without any state permit, but purchasing a new firearm from an FFL still triggers the federal NICS background check and the Form 4473 attestation.

Texas TCUP, LTC, and HB 1927 Permitless Carry

The Texas Compassionate Use Program is administered by the Texas Department of Public Safety, which also administers the License to Carry. Texas does not issue physical medical marijuana cards. Patient prescriptions are entered into the Compassionate Use Registry of Texas (CURT) and verified at dispensation by ID and partial SSN lookup.

Texas HB 46, effective September 1, 2025, expanded TCUP from the previous 1 percent THC by weight cap to 10 mg of THC per dose with a 1 gram per package limit, authorized non-smoked pulmonary inhalation (vaporization), and added chronic pain, gastrointestinal disorders including Crohn's disease, and traumatic brain injury to the qualifying-conditions list.

DPS has stated that participation in TCUP does not automatically prevent LTC qualification or gun ownership under state law. DPS does not impose special background checks targeting CUP participants. The agency retains authority to refer an LTC application to the Medical Advisory Board if the underlying medical condition (uncontrolled epilepsy, advanced terminal cancer, neurodegenerative disease) might impair firearm competency.

Texas HB 1927, effective September 1, 2021, authorized permitless concealed and open carry for eligible Texans. Federal law is unchanged. Every Texas FFL purchase still executes the federal NICS check and Form 4473.

Practical Risk for Patients: Purchase vs. Possession vs. Carry

Federal exposure varies dramatically by the specific action.

Purchase from an FFL is maximum federal exposure. The signed Form 4473 is documentary evidence of the offense, the statutory penalty reaches 15 years, and the conviction rate on prosecuted cases approaches certainty. The proposed 2026 form revision may reduce this exposure for medical patients once finalized, but the current form is the operative form.

Possession of pre-owned firearms carries lower and decreasing risk for state-compliant non-violent patients. The Daniels and Eleventh Circuit rulings, the January 2026 ATF Interim Final Rule, and Acting Attorney General Blanche's stated reconsideration of these prosecutions all point toward reduced enforcement priority. The risk is not zero.

Carrying under state permitless-carry laws is state-low federal-conditional. State law enforcement generally does not enforce federal firearms law, but the discovery of a firearm and cannabis together during a traffic stop or self-defense incident can escalate to a federal referral, particularly if aggravating factors are present.

Why This Is a Legal Question, Not a Medical One

Miracle Leaf® physicians certify medical need under Florida Statute section 381.986 or the Texas Compassionate Use Program. Legal strategy under federal firearms law belongs entirely with a Second Amendment attorney licensed in your state. The interaction of section 922(g)(3), the evolving Form 4473, the January 2026 Interim Final Rule, Bruen, Daniels, the Eleventh Circuit revival, and the narrow June 2026 Hemani decision creates a fact-specific analysis that no clinic can perform.

Patients with active MMUR or TCUP registry status who already own firearms, or who are weighing a future purchase, should secure counsel before acting. Florida and Texas bar associations maintain lawyer-referral services that can match patients to firms with current Second Amendment practice.

Disclaimer

This post is informational and is not medical or legal advice. The intersection of medical marijuana patient status and federal firearms law carries severe federal felony exposure under 18 U.S.C. section 922(g)(3), 18 U.S.C. section 922(a)(6), and 18 U.S.C. section 924(a)(1)(A). The legal landscape is highly volatile, with the Supreme Court's narrow June 2026 ruling in United States v. Hemani leaving many questions open and the ATF actively revising Form 4473 through a rulemaking whose public comment period closed August 6, 2026. Marijuana remains federally controlled even after the April 2026 Schedule III reschedule. Any patient considering purchasing a firearm, applying for a state-level permit, or possessing a weapon while holding an active medical marijuana card must consult a Second-Amendment-licensed attorney in their state. Miracle Leaf physicians certify medical need; legal strategy belongs with qualified counsel.
