Well I smoke daily and really love my weed, but I don't think it would be my "drug of choice". This is a hard question. It's between Oxycontin/Heroin, Xanax, and LSD. I guess I do the most oxycontin of anything.
Cannabis, LSD, Shrooms, any pshycadelics I can get my grubby little paws on although right now I'm fucked off my ass off 2 10mg vics and tommorow I'll being doin E for the first time
