Smoking poisons your body, increases your chances of getting cancer, and pollutes the air for everyone around you. It's never cool. It's flat-up stupid, and anyone who gets into smoking because they think it's cool is a patent idiot.
If you're going to intentionally harm yourself, at least have the courtesy to get into things like cutting. At least then you're not harming people around you.
Cutting hurts other people than the one who's doing the cutting. It's an addictive, self-destructive behavior that is psychologically damaging to the cutter, but is troublesome to other people around the cutter as well. A good friend of mine used to cut, and it not only destroyed her life at the time, it pulled on everyone else that she knew as well.
If you're going to intentionally harm yourself, just play football. :thumb:
Or rugby...
Oh, and for the record, smoking is not only a bad habit, it can directly lead to death. Aside from looking cool, there's no reason anyone should pick up a cigarette (and if looking cool is so important to you, there are other ways to look cool than close your own casket a few years earlier).
