In a way, it's the same with alcohol. My kids have friends whose parents are heavy drinkers. I'm leary letting them hang out there a lot because I don't want them thinking that this is what people should do. Also, things happen when people drink heavy (fighting, arguments, lack of supervision and the such) and I don't want them caught in the middle of something. It's going to be the same way with bud. Some parents aren't going to want their kids subjected to second hand smoke or watching people smoke. I got told by my oldest daughter the other day that she smoked a joint with friends. Hypocritically, lol, I told her I didn't want her making a habit of it until she finishes school. I did tell her I'd rather she smoked than drank but I really would wish she'd hold off getting into heavy smoking until she's of legal age. Why? I don't know. I guess it's just what parents say, lol....
