I might be the only person in the world who didn't smoke marijuana till I was 26 and got high and liked the feeling. Maybe the best I ever felt. It was very comforting. That was 20 years ago and I have never smoked it since. So that should tell you if it is addictive. The problem for me I didn't smoke cigarettes and trying to hold in the marijuana smoke was very difficult. I would love to have tried pot brownies or a vaporizer. The thing with marijuana it doesn't have calories like beer. The alternative ways of using should mean marijuana has not adverse affects. When I came up I thought of pot smokers as long hair hippies and marijuana stunk and you got high like a zombie. The smell really turned me off.
