Can I own a firearm if I have a New York medical marijuana card?
One of the most pressing questions that a potential medical marijuana patient can pose and it requires a very clear and direct answer, if you are a gun owner or thinking of acquiring a firearm, Knowledge of how having a medical marijuana card will impact your rights is paramount before you apply.
The answer is complicated, and is centered around the conflict created by both federal and state law. Here is what you need to know.
The Federal Law Problem
Despite what the State of New York law may say regarding medical cannabis, you are still first subject to federal law when it comes to owning firearms and the federal government does not recognize the two together.
The Gun Control Act of 1968 makes it illegal for any “unlawful user of or addicted to a controlled substance” to own or purchase firearms. Since cannabis still remains a Schedule I controlled substance under federal law (the same category as heroin), the federal government views all cannabis users including medical marijuana patients as people who are prohibited from having firearms.
There is no gray area on this issue, and it’s not a matter of interpretation, the ATF has spoken about this issue repeatedly over the years.
The ATF Form 4473
If you’ve ever bought a gun from a federally licensed dealer, you’ve had to complete ATF Form 4473 – the federal gun transaction record. Box 21(f) within the form is where you are asked if you are an unlawful user of or addicted to marijuana and/or any other drug.
The form contains a distinct warning indicating that marijuana remains illegal on a federal level, regardless of what the state may say. Answering ‘no’ as a medical marijuana cardholder and thus a cannabis user could be considered a federal felony for providing false information on a federal firearms form.
The dilemma between the problem faced by medical marijuana users is whether or not they want to tell the truth and be denied, or lie about their use and run the risk of being charged with a federal crime. There is no good answer to this question, which makes it imperative that any person who may choose to apply for a medical marijuana card gives this matter their careful consideration before acting.
What Has the Court Said?
Federal courts have primarily agreed with the ATF’s stance on this issue. The case of U.S. v. Daniels was an illustration of this situation, as it addressed whether the Federal prohibition against gun ownership for cannabis users is constitutional. While courts have had some back-and-forth on Second Amendment grounds, there is no court that has ruled in favor of providing clear and/or uniform protections to medical marijuana patients seeking to own firearms.
As of 2026, no clear legal victory has been achieved in favor of gun-owning medical marijuana patients at the Federal level. The Federal prohibition continues to remain in effect until either Congress modifies current law or a definitive ruling by the US Supreme Court alters the framework.
Does New York State Law Offer Any Protection?
The law regarding the possession and use of firearms in New York is very strict and has minimal provisions for purchasing and possessing firearms, when a federal law prohibits it. The federal prohibition does not allow New York to allow you to purchase or own a firearm under any circumstance.
There is no specific state-level prohibition about using medical marijuana cards as disqualifiers for purchasing or possessing firearms, but Federal law is the governing law of the land when it concerns gun purchases from federally licensed dealers—not many firearm purchases are not made from federally licensed dealers.
What About Concealed Carry Permits?
New York’s process for obtaining a concealed carry permit includes background checks and disclosures. Although medical marijuana cards do not get reported automatically to the firearm licensing bureau, providing false information on any application for a permit is a serious crime.
When applying for a concealed carry permit, if there is a question regarding whether you have used a controlled substance or not. If the question is answered in an untruthful manner then you are create a legal risk. Cannabis is still illegal at the federal level, so if you disclose that you have used cannabis and it is discovered then your application will be denied. This illustrates one of the many discrepancies between the New York state cannabis laws and federal firearms laws, which create a significant challenge to the patient.
The Practical Reality for Current Gun Owners
While many gun owners who take medicinal marijuana don’t go through licensed dealers for their new gun purchases, that still leaves questions about whether they are allowed to own guns.
The federal law that prohibits someone from possessing firearms due to their status as an “unlawful user” of marijuana uses the same criteria regardless of whether someone is a medical patient or not, so while there are not likely many prosecutions for the possession of firearms by those who have received mediated use of cannabis, the potential for prosecution definitely exists.
If you find yourself in a situation like this you should talk with an attorney who specializes in the area of firearms law, has some knowledge of federal laws and regulations in New York State, and can help determine what actions would be taken based upon your specific circumstances.
Will Getting a Medical Card Automatically Flag You to Gun Authorities?
In New York, medical cannabis patient records are maintained by the Office of Cannabis Management and are treated as confidential health information. Your registration as a medical patient is not automatically reported to the ATF, the FBI’s NICS database, or state firearms licensing authorities.
However, confidentiality protections don’t change what federal law says about cannabis users and firearms. And if your medical cannabis use comes to light during any firearms-related legal proceeding – through a background investigation, a search, or other circumstances – the federal prohibition would apply.
The absence of automatic reporting is not the same as legal protection.
Who Is Most at Risk?
The conflict between medical cannabis and gun rights is most acute for:
- Active duty military or law enforcement who are subject to drug testing and strict federal firearms rules
- People applying for new concealed carry permits who must disclose controlled substance use
- Anyone purchasing a new firearm through a licensed dealer while holding a medical card
- People under federal supervision (parole, probation, or other federal oversight) where controlled substance use is closely monitored
If any of these describe your situation, the stakes are higher and legal counsel is strongly recommended before applying for a medical marijuana card.
Should You Choose Between Your Card and Your Gun Rights?
Ultimately, whether or not you take medical marijuana is a very personal choice. No one can make that choice for you. It is important for you to do so with as much information as possible. Many medical cannabis patients perceive the increased quality of life and symptom relief to be worth the downside of being unable to purchase a gun.
On the other hand, if you need your firearm for a job, to keep yourself or family safe, or because you enjoy hunting, the tradeoff could be unacceptable to you. The most unacceptable thing is to make that decision without having a complete understanding of what is really at stake in terms of both state and federal laws. There are people who believe that medical marijuana is legal in New York so they can have no Federal consequences.
If you believe that, you could find yourself in serious trouble with the law. The certification process is simple for those who qualify as a medical cannabis patient and don’t care about the firearm issues, or for those who also have a firearm decision to make but would like to proceed with obtaining the NY Medical Marijuana Card. You can work with licensed New York state practitioners and have a quick telehealth appointment.
Could This Change in the Future?
It’s possible. There appears to be an increasing amount of bipartisan pressure in Congress to eliminate cannabis from Schedule I which will significantly modify the firearms situation under the law federally. Many bills have been proposed in the last few years that would reschedule cannabis or protect cannabis users who comply with state law from firearm prohibitions under federal law.
As of 2026, this momentum towards legislation regarding the rescheduling of cannabis has been real and any ruling on the rescheduling process of this marijuana is currently under formal review of the federal government could provide significant changes regarding firearms and cannabis.
The Bottom Line
At present, cannabis consumers, even if they are registered patients using medical marijuana, cannot buy or possess firearms under federal law. Although New York has an acceptable medical cannabis program at the state level, neither state law nor the program nullifies the federal laws prohibiting cannabis users from purchasing or possessing firearms.
If you are uncertain if you can use your medical marijuana card and still own possession of firearms or ammunition, please consult with a qualified attorney who is knowledgeable about both firearms law and cannabis laws in New York prior to making any decisions.
Frequently Asked Questions (FAQs)
Does getting a New York medical marijuana card automatically disqualify me from owning a gun?

Your medical cannabis registration is confidential and not automatically reported to firearms databases. However, federal law still prohibits cannabis users from purchasing firearms, and answering falsely on ATF Form 4473 is a federal felony.
Can I keep firearms I already own if I get a medical marijuana card?
Federal law prohibits unlawful users of controlled substances from possessing firearms, not just purchasing them. While enforcement against medical patients in this context is rare, the legal exposure technically exists. Consult a firearms attorney for guidance specific to your situation.
Is there any way to legally have both a medical marijuana card and own a gun in New York?
Not under current federal law. Until Congress changes cannabis’s federal scheduling or explicitly protects state-legal cannabis users from firearms prohibitions, the conflict remains unresolved.
