AquariumRescueUnit Reviewed by AquariumRescueUnit on . Tips for smoking in a dorm? Im headed to Uni this year and wondering whats a good way to smoke in my dorm room without a)/ making the hall reek, b). making anyone the wiser. My roomie smokes too so hes chill with it. I wa sthinking just facing a box fan out of the window and smoke next to it, dont wanna use a sploof or doob-tube since they help, they just make your room smell like laundry with a bit of weed.
