In Texas, patients in the Compassionate Use Program (CUP) may still legally own or purchase firearms, but there are important caveats. Texas does not treat enrollment in the CUP as a disqualifying factor for gun ownership. However, federal law classifies marijuana — even medical marijuana — as a controlled substance. Under federal rules, anyone who uses cannabis is prohibited from possessing firearms.
Here’s how it breaks down:
Texas law: Being a CUP patient does not automatically prevent you from owning or buying a gun.
Federal law: Cannabis use (including medical use) is considered unlawful, so federal firearm restrictions technically apply.
Medical condition caveat: If your condition affects your ability to safely handle a firearm, you may lose your right to own one, regardless of CUP status.
