I had like 4 possible dealers, all sophomores or juniors in high school, but one girl when out of business because she was getting too well known around school or got caught or something. shame too, she was my favorite. but my catholic school is full of stoners so there are many other dealer people. In SF though I think it would be pretty hard to break into the market if you don't have a medical marijuana perscription, because that's where the good weed comes from.
