With the recent changes in Maryland law concerning medical marijuana, see MD Code, Health - General, § 13-3304 et seq., and the push to legalize the use of marijuana in Maryland, a recurring issue is how such marijuana use would affect your Second Amendment rights. The short answer is that it may well act to abrogate those rights by (1) barring a FFL from selling a firearm to such a user and (2), by making such a user a prohibited person under federal law.
