Can You Legally Own A Gun With A Medical Marijuana Card In Pennsylvania

Can You Legally Own A Gun With A Medical Marijuana Card In Pennsylvania?

So, can you legally own a gun with a medical marijuana card in Pennsylvania? The answer is no, but with a lot of gray area that needs to be addressed. The US Federal Gun Control Act of 1968 prohibits ‘unlawful users’ of controlled substances from owning a firearm. To this very day, cannabis is categorized as a Schedule I substance under the US federal law making medical marijuana card holders ‘unlawful users’ of a controlled substance. 

Even with the ATF being quite vocal on this matter, there are some legal loopholes and a lack of implementation of these laws, causing a lot of confusion. Today, let’s take a look at the legality of owning a firearm in Pennsylvania with a medical marijuana card through the eyes and years of operational experience of CertaMD,

Here’s why you shouldn’t get a medical marijuana card with an existing firearms license

In Pennsylvania, individuals holding a medical marijuana card face legal challenges concerning gun ownership due to conflicting state and federal laws. Although the state of Pennsylvania allows the use of medical marijuana, federal law, specifically the Gun Control Act of 1968, prohibits firearm possession by anyone using controlled substances, including marijuana. 

This federal prohibition is enforced by the Bureau of Alcohol, Tobacco, Firearms, and Explosives (ATF), and Pennsylvania State Police are bound by these federal laws. As a result, even if you legally use medical marijuana in the state, owning or purchasing a firearm violates federal law, particularly under 18 U.S.C. 922(g)(3), which restricts users of controlled substances from possessing firearms.

The ATF has made it clear countless times that marijuana users, regardless of state legality, cannot possess or purchase firearms. This applies even when filling out the Firearms Transaction Record form, where marijuana use must be declared. Even if someone owns a gun and later obtains a medical marijuana card, they are advised to transfer ownership of the firearm within 60 days to comply with federal law. 

Despite ongoing debates and potential reforms, medical marijuana cardholders must carefully navigate these restrictions and may seek legal advice to understand their responsibilities under both state and federal law. If you’re not sure where to start, our experts at CertaMD are always ready to help you through.

Reclaiming your firearms license once your medical marijuana card expires

In states like Pennsylvania, reclaiming gun ownership rights after a medical marijuana card expires involves navigating both federal and state legal frameworks. Under federal law, marijuana use, even for medicinal purposes, classifies an individual as an “unlawful user” of a controlled substance, making them ineligible to possess or purchase firearms. The ATF enforces this restriction, and any federal firearms licensee who knowingly sells a firearm to a marijuana user violates federal law. 

However, once the medical marijuana card expires, individuals may be able to regain their right to buy firearms, but they must no longer be classified as unlawful users to comply with federal regulations.

Pennsylvania state law itself does not specifically prohibit former medical marijuana cardholders from owning firearms, but federal restrictions remain in place. After the card’s expiration, an individual’s status as a medical marijuana user might no longer be flagged in background check systems, which could open the possibility of regaining gun ownership rights. 

Remember, it’s critical to answer truthfully on ATF Form 4473 when purchasing a firearm, as any false statements could lead to ‘perjury’ charges. You must also not be otherwise disqualified from owning a firearm under state or federal law, such as having certain criminal convictions.

Can CBD oil users own a firearm in Pennsylvania?

Fortunately, there are no legal restrictions on both federal and state levels for CBD oil users when it comes to owning a firearm. This means that yes, CBD oil users can legally own a firearm as long as the products is hemp-driven and have less than 0.3% THC content.

In Pennsylvania alone, a large variety of CBD oils is available to the state’s adult population via a network of dispensaries. This ensures that the THC rating mentioned on the packaging is actually accurate. Although the chances of it happening are very slim your cannabis test can come back positive if you’re not using quality CBD oils which contain way over the labelled 0.3% THC content.

Final Note

As long as cannabis is categorized as a Schedule I substance under US federal laws, there will be a gray area around the interaction between the state and federal laws on the matter of gun ownership for medical marijuana users. Although your medical marijuana card should provide you legal immunity to exercise your right to own a firearm in Pennsylvania, the US federal laws and the ATF will always have the final say.

Individual results and treatment response

Medical cannabis does not work the same way for every patient. Symptom relief can depend on factors such as the type of product (THC/CBD ratio, route of administration), dose, frequency of use, underlying medical conditions, concurrent medications, and lifestyle variables like diet, stress, and sleep.

Because response and tolerability vary, ongoing follow-up with your CertaMD provider is important to review benefits, monitor side effects, and adjust your treatment plan safely over time.

Possible risks and side effects

Like any therapeutic option, medical marijuana can cause side effects. Commonly reported effects include dry mouth, dizziness, fatigue, red or irritated eyes, increased appetite, headache, and temporary problems with attention, concentration, or short-term memory.

Some patients, especially with higher-THC products, may experience anxiety, rapid heartbeat, worsened mood, or perceptual changes; in rare cases, serious effects such as psychosis, significant mood changes, heart rhythm disturbances, or cannabinoid hyperemesis syndrome (recurrent nausea and vomiting) have been reported. If you notice severe, unexpected, or persistent symptoms, stop using cannabis and contact your healthcare provider or seek urgent care.

Legal and regulatory notice

Medical marijuana programs are created and regulated at the state level, and eligibility, product access, and telemedicine rules vary by jurisdiction. Under U.S. federal law, marijuana remains a Schedule I controlled substance, and clinicians typically “recommend” or “certify” medical cannabis use rather than prescribe it in the traditional sense.

Some states require an initial in-person visit before medical cannabis certification, while others allow both initial and renewal evaluations via telehealth; CertaMD operates within the specific requirements of each state it serves.

Product quality, sourcing, and safety

For your safety, use only medical cannabis products obtained from licensed, state-regulated dispensaries that perform appropriate laboratory testing for potency and contaminants. Unregulated or illicit products may contain pesticides, heavy metals, microbes, or inaccurate THC/CBD concentrations, which can increase health risks and lead to unpredictable effects.

Ask your CertaMD clinician or dispensary pharmacist about product selection, dosing, onset and duration of effects, and how to store products safely away from children and pets.
