well,Speel, all kinds of dumb stuff can be entertaining.
that's got nothing to do with real life. my cousin - who was younger than me - smoked since she was in her teens and when she was in her mid-30's got cancer. i can't say if it was smoking-related (it wasn't obvious, like lung-cancer), but she couldn't stop smoking and was dead in 2 years.
I've never smoked, taken drugs, etc, but no matter how often you encourage people not to hurt themselves, sometimes these things are out of their control. or so it seems.
it's very complex and there are no easy answers.
it's very sad.
