what is it with rock bands and cigarettes??!

i don't know about elsewhere in the world, but in taiwan, people in bands drink a lot of beer and chain smoke like their life depends on it. it really is annoying and they seem to think that they're elite or whatever. don't get me wrong, i dabble in rock music, and i play some guitar and drums, i just don't see the connection between getting intoxicated and getting drowned in smoke and rock and roll.
