I apologize for the friend thing, but what I meant was that was a pretty pointless post. Just because you know people that get high and are living normal lives, doesn't mean it doesn't have consequences.
Rather, if you really care about your friends, you should help push them in a positive direction. If you're really only 15, that's a definitely young age to be involved (or rather, have friends your age-if they are your age-being involved) with drugs. Like I said to shadow, there's so many things that make you feel just as good without the consequences that marijuana will later present. And you can have just as much fun doing them, if not more ;)
Again sorry ^_^
