Your best bet is to get a real job and just sell to friends. That's what I do. I buy a half ounce at a time, sell grams to friends, and smoke some. I don't smoke for free, but I smoke for a lot less money than a lot of other people.

Oh, and don't trust schwag. You want to develop a reputation for quality and convenience, and selling bad weed is the quickest way to lose that. Besides, you meet better people when selling better weed.
