Can You Own a Gun After Your Medical Card Expires in PA?

You can own a gun after your medical marijuana card expires in Pennsylvania only if you have actually stopped using cannabis and enough time has passed that your use is no longer “continuing into the present.” A lapsed card by itself does not restore your firearm rights under federal law, because the prohibition targets your status as a user, not your status as a state cardholder.¹

Why an Expired Card Doesn’t Automatically Fix the Problem

The federal Gun Control Act, at 18 U.S.C. § 922(g)(3), makes it illegal for any “unlawful user of or addicted to any controlled substance” to possess a firearm or ammunition.² Because marijuana remains a Schedule I substance under federal law, any use of it counts as “unlawful,” regardless of Pennsylvania’s medical program.

The key word is “user.” Federal enforcement does not turn on whether you hold a state-issued medical marijuana card. It turns on whether you are actually using cannabis. An expired card signals that you have stopped buying from state-licensed dispensaries, but it does not prove you have stopped consuming. The federal government does not track state card status, and NICS receives no automatic notification when a Pennsylvania card lapses.

Pennsylvania cards must be renewed every 12 months with a $50 fee and a new practitioner certification.³ Letting the renewal deadline pass changes your relationship with the state program, not your federal firearms status.

What the ATF’s 2026 Rule Actually Says About Ceasing Use

In January 2026, the ATF published an interim final rule that narrowed the definition of “unlawful user.” Under the new standard, you qualify as an unlawful user only if you “regularly use a controlled substance over an extended period of time continuing into the present.” Someone whose use was “isolated or sporadic,” or who has stopped entirely, is no longer prohibited.¹

The rule also states that the prohibition lifts once a person has “ceased regularly unlawfully using the substance.” It does not, however, specify a fixed waiting period. The older regulatory examples that referenced a one-year lookback have been removed. That leaves a genuinely uncertain gap between the day you stop and the day you can safely claim you are no longer a user.

One safe harbor in the rule does not help you: the exception for people using lawfully prescribed controlled substances. Doctors cannot prescribe marijuana because of its Schedule I status. Pennsylvania’s program uses “certifications” from approved practitioners, not federal prescriptions, so cannabis patients get no protection from the prescription carve-out.

The Form 4473 Problem

The moment a card-expiration question becomes concrete is the moment you walk into a gun shop. Every purchase from a licensed dealer requires ATF Form 4473. Question 21.f asks whether you are “an unlawful user of, or addicted to, marijuana or any depressant, stimulant, narcotic drug, or any other controlled substance,” followed by a bolded warning that marijuana use “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.”⁴

If your card has expired but you are still using marijuana, answering “no” is a false statement on a federal form, which is a separate felony punishable by up to 10 years in prison.⁵ Answering “yes” gets the sale denied. If you genuinely stopped using marijuana before the card expired and enough time has passed that your use is no longer “continuing into the present,” you may be able to answer “no” truthfully. Misjudging that timing is the felony trap.

Penalties for Getting It Wrong

A conviction under 18 U.S.C. § 922(g)(3) for possessing a firearm as an unlawful user carries up to 15 years in federal prison.⁶ The Form 4473 false-statement charge, up to 10 years, can be stacked on top.⁵

Prosecutors do not need to catch you smoking with a gun in your hand. Under the government’s theory in recent cases, regular marijuana use combined with a firearm anywhere in the home, even locked in a safe, is enough. A felony conviction also brings a permanent federal firearms prohibition on top of the prison exposure.

Practical Steps to Restore Your Eligibility

If you want to move from medical marijuana patient back to lawful firearm owner in Pennsylvania, the path requires more than waiting for an expiration date.

Stop using marijuana entirely. This is the threshold. Under the 2026 ATF rule, the prohibition only lifts once you have “ceased regularly unlawfully using” the substance, and recent use still disqualifies you because it is “continuing into the present.”¹
Let the card lapse or surrender it. Card status is not what federal law targets, but an active card is evidence that could be used against you. Relinquishing it demonstrates intent to stop.
Build a paper trail. Clean drug test results over a period of months, doctor records showing you have discontinued cannabis, and documentation of any switch to alternative treatments all matter if your eligibility is ever challenged.
Talk to a firearms attorney before you buy. The interaction between the evolving ATF rule, pending Supreme Court litigation, and Pennsylvania law creates real uncertainty about timing. Firearm rights restoration cases typically run between $1,000 and $5,000 in legal fees.

A formal federal relief process exists through ATF Form 3210, but Congress has repeatedly defunded the ATF’s ability to process individual relief petitions, so this avenue is largely unavailable in practice.

Pennsylvania’s Own Rule on Carry Licenses

Even setting federal law aside, Pennsylvania imposes its own restriction. The Pennsylvania State Police Firearms Division has taken the position that holding a medical marijuana card and a License to Carry Firearms at the same time is prohibited. Carrying a concealed firearm without a valid license is a felony of the third degree under 18 Pa.C.S. § 6106.⁷

Once your card expires and you have genuinely stopped using cannabis, the state-level bar to holding an LTC falls away in the same way the federal bar does. Some Pennsylvania legislators have introduced bills to decouple medical marijuana status from firearm rights, but as of 2026 no such legislation has passed.

A Supreme Court Decision Could Change the Answer

On March 2, 2026, the Supreme Court heard oral arguments in United States v. Hemani, a case involving a defendant who used marijuana roughly every other day and kept a pistol at home.⁸ Several justices questioned the vagueness of “unlawful user” and whether historical laws disarming “habitual drunkards” really support a rule that strips firearm rights from someone who is sober at the moment of possession.

A decision is expected by summer 2026. If the Court narrows or strikes down Section 922(g)(3) as applied to marijuana users, the entire calculation for a Pennsylvania patient with an expired card shifts. If the Court upholds it, the analysis above holds: cessation of use, documented over time, is what actually restores your ability to lawfully own a firearm. Until that ruling lands, the safest position is the one the law already describes. Stop using cannabis, document it, then buy.
