@KristinaM I have never heard of someone smoking weed, and then go home, and beat on his wife and kids, or kill his best friend over a stupid argument.
I generally lean towards the side of 'do what you want, just don't hurt anybody.'. So, that being said, medical marijuana shouldn't be weaponized against people in any way. So no, I'm not in favor of that.
Besides, stoners are no threat to anyone anywhere. Sitting on the couch, eating potato chips and watching Cartoon Network reruns is NOBODY'S idea of dangerous.
Marijuana can push a person into schizophrenia. So probably not the best combo. Alcohol can make a person careless but doesn't cause psychosis. But I still wouldn't trust an alcoholic with a gun. If for no other reason than alcohol and guns combined tend to be a cause of suicide.
