You don't need to smoke to have fun, though, which is the hole in your argument.
I do know for a fact that a lot of the people at my high school smoke weed and drink at parties. Dunno about cigarettes though. They aren't very popular.
The guys who do this are usually in the "dumber" classes though. You probably know what I'm referring to, like Weight Training.
I roomed with a very nice guy who admitted that he smoked marijuana last summer though. He was pretty smart too and was in great shape and healthy.
Its funny to me. If my parents met him, they would probably really like him (actually my mom might not, cuz she's racist and he is african....but...anyway). However, if they knew he smoked, they would instantly hate him no matter what. From a parental view, it's logical, of course. But he was in no way a bad influence. Never really talked about it until we stopped by a bong/hookah shop in Munich. I never felt the urge to smoke due to him either.
