I know somebody who smokes marijuana on a daily basis this person is dear to me. he is almost bipolar and he is always lashing out and yelling. help?

Anger management: Does he have 4 teenage kids by any chance who think they know it all?? LOL! Anyways, since plenty of people don't smoke marijuana and still yell and lash out a lot I'm not sure that's a factor. When you say he's ALMOST bipolar..I'm not sure what you mean....how much farther does he have to go to get there? If your friend is aware of this behavior as a problem- is he willing to talk about it?
