1. Primo quality weed (I drive over an hour to pick up from someone who consistently has extremely potent strains) is super expensive. Luckily I only smoke a couple times a week so one or two bowls is usually enough to get me pretty damn high.

2. Legality and social acceptance issues are still a major problem. I have so many friends who think that because I occasionally toke I'll be shooting up smack in a few months.
