I have a former friend who used to be a pretty fun guy, but over the past few years he has started smoking weed more and more frequently. He's at the point where he is legitimately high all the time. It's hurting his grades, he's wasting all of his money on it, and he smells like a junkyard dog (seriously it's rancid). I tried to convince him to cut down on it, but he just gets all worked up about me "judging him" and argues that because it does no physical harm to him it's not hurting him in any way. We don't talk much anymore but I still have to see him everyday. He is the main reason I will never touch marijuana.
