So Im buying a house. I'm only 19 and was lucky enough to have a chunk of change. So I'd prefer to keep my illegal activities private, so as not to interfere with my ongoing luck I have people that will live with me who smoke too, but I dont know whay my neighbours views are, and dont want to really find out. I dont mind my entire house smelling like weed, but I dont want that smell to leave. If me and my roomies pack like 4 or 5 bowls and used a bong, air filtering fan and smoke buddy. What are the odds of the smell leaving the house?
