ok i live in a dorm this is what you do to keep it not smelling, get a small fan you can put up to the window drop the blinds to the top of the fan and shut the window on the fan now a towel and put it around the sides of the fan so it looks like a tunnel going into the fan if you did it right you can hold a lighter or a smoking blunt in front of it and it will suck it out perfectly... and yes dont use a bong.... tell me if that works
