In the case of medical or recreational marijuana, there is a conflict between state and federal laws. What is known, is that on a federal level, marijuana is a Class 1 prohibited drug, and a person may not possess both a firearm and a Class 1 drug at the same time under federal firearms laws.
However, a medical marijuana card is not actually marijuana itself and possession of both a state-issued medical marijuana card and a state-issued concealed-carry carry permit is not settled law. A person’s legal situation regarding holding both is dependent upon individual state(s) laws that may also be in conflict with each other depending on the state(s) in question. If you have a medical marijuana card and a conceal carry permit, we advise you to consult an attorney to advise you on your particular situation.
