Can You Own a Gun and Have a Medical Marijuana Card in Missouri?

Under Missouri law, you can use medical marijuana. Under federal law, you can own a firearm. But combining the two puts you in legally murky territory - and the conflict isn't theoretical.

These are two rights that Missourians care about deeply, and they don't sit well together under current federal law. This article breaks down what Missouri's legal climate actually means for gun owners who use medical marijuana - and vice versa. Keep in mind that both gun and marijuana regulations vary by state, so everything here is specific to Missouri.

Who Can See Your Medical Marijuana Records

Before you can get a medical marijuana card in Missouri, you need a physician's recommendation and a qualifying medical condition. Your application goes through the Missouri Department of Health and Senior Services (DHSS), and once approved, your card information is stored in a state database.

Access to that database is limited. The only parties who can look up whether you hold a card are law enforcement and licensed cannabis dispensaries - and even then, their access is narrow. They can verify that a card is valid, but they cannot pull your medical records. Those are protected under HIPAA.

Here's the short list of who can access your marijuana card status:

• Your physician
• Missouri Department of Health and Senior Services
• Law enforcement
• Licensed cannabis dispensaries

Your medical history stays private. Card status verification is separate from your clinical records.

Where Federal Law and State Law Collide

Missouri's Constitutional Article XIV protects your right to access medical marijuana and does not restrict firearm possession or purchase on its own.

Federal law is a different story.

The ATF classifies marijuana as a Schedule I controlled substance, regardless of whether your state has legalized it medically or recreationally. Under federal law, it is illegal for a known marijuana user to purchase or possess a firearm.

This plays out at the gun counter in a concrete way. When you buy a firearm from a licensed dealer, you fill out ATF Form 4473. One of the questions asks whether you are an unlawful user of, or addicted to, marijuana or any other controlled substance. Since marijuana remains federally illegal, medical marijuana patients technically fall into this category.

Answer "yes" and the sale is denied. Answer "no" when you hold a medical marijuana card and use cannabis, and you've made a false statement on a federal form - which is a federal crime.

What This Means If You're Already a Card-Holding Gun Owner

If you already own firearms and then apply for a medical marijuana card, you are - under strict federal interpretation - in violation of federal law by continuing to possess those firearms.

Missouri is not actively cross-referencing marijuana card databases with gun ownership records, and there is no indication the state is looking to report its citizens to federal authorities for this combination alone. As a practical matter, this situation is unlikely to result in action unless you are involved in other criminal activity.

That said, the legal exposure is real. Applying for a medical marijuana card does not ask about firearm ownership, and it is unlikely anyone will check - but "unlikely to be enforced" is not the same as "legal."

Will This Change?

It could. Federal legislation - including past versions of the MORE Act - has sought to remove marijuana from Schedule I, which would eliminate this conflict at the federal level. However, as of this writing, no such change has been signed into law, and the ATF's position has not shifted.

Until Congress acts or the DEA reclassifies cannabis, the tension between state-legal marijuana use and federal firearms law remains. Keep an eye on federal legislative progress if this issue affects you directly.

The Simple Version

Missouri lets you have a medical marijuana card. Missouri also doesn't restrict gun ownership on its own. But the federal government still classifies marijuana as a Schedule I drug, which makes it illegal under federal law to purchase or possess a firearm if you're a marijuana user - card or not. Missouri isn't hunting down cardholders who own guns, but the legal risk is real. If this situation applies to you, understand both the state and federal landscape before making any decisions, and consult a legal professional if you need specific advice.
