My experience ...
Well, I smoked pot too and my AH made sure it was always around for me - because then I was mellow and relaxed - then the light went on - as long as I was toking up he could point at me and call me a pothead, thereby justifying his own drinking and addiction. So I stopped.
Something to consider .... I've known a couple of people who were addicted to pot and I have seen it become just as destructive as other drugs. It can be a depressant for some.
