Now you have me all freaked out...I live in student housing right off of the elevator..and I smoke weed in my room all the time. I smoke out the window though and blow it out a paper towel roll with a dryer sheet in the end; and I also keep a towel under the door crack. So I am being pretty cautious about the whole situation. I obviously am extremely paranoid, I just really don't want to get in trouble...eeeek.
