Does Maryland accept out-of-state medical cards?
No. Only Maryland residents can register as patients, and MCA warns that carrying cannabis across state lines is illegal.

Your Maryland card is issued under Maryland law, so other states decide for themselves whether to honor it. Never carry cannabis across state lines — that's a federal offense, including on flights.
