Last summer I used to just crack my window and smoke blunts right in my room, I have no fucking idea how I got away with that cuz my entire room smelled like grape dutches constantly.
After I got arrested for posession and my parents got the idea in their head that its a possibility I could be smoking weed in my room, I got more careful. Open window, only smoke bowls (no blunts inside anymore
), use a sploof, spray a bit of cologne (I find cologne works better becaue 3-4 small sprays around your room and the whole entire room will smell like nothing but cologne for a good amount of time), and towel the door. Also, a lock on your door really is best, no way would I do it otherwise. I'm also the only one whose bedroom is on the first floor of my house so thats a plus...
