I would go for a walk in a secluded area. or a bike ride. I smoked a blunt in one of the dorms i lived in while in college. And after me and my buddy got done with it (we covered it in hersheys chocolate so it lasted a while) we heard a knock at the door. I looked through the hole and saw some random guy. I opened the door and said hello. He told me that he smelled the herb and that i should be careful. I was blown away and couldn't think of much to say other than, "ok thanks." So that really freaked me out and it was the last time i smoked a blunt in my room.
