Because I shoot up, I prefer to do it in my room, alone or with my closest friend and dearest drug buddy, while nobody else is home because I experience paranoia on a scale that I never thought possible (I have thought I heard entire conversations between my landlord and their spouse about finding out we use meth, that they're calling the police, and that they are going to evict us... only to find out they were out of town). Many of my amigos shootup at work, in public restrooms, and anywhere else. I however find that to be inappropriate and disrespectful and therefore only use at home, with the rare exception I might shoot when I am picking up with my connect.
