I don't live in dorms. I have a nice loft apartment, but the guy I share it with (a family friend also at Yale) is a religious freak who thinks that weed is from satan. Makes me glad i'm jewish, quite frankly. I just go up on the roof of the building, and can smoke all day and night. If it's bad outside, or I just don't feel like it, I just go in the bathroom and put on the exhaust.

No vent? That toilet-roll fabric sheet never worket for me. I just smoke a fat cigar and it covers it up pretty good.
