Has cigarette smoke really been identified as a hazard to the environment? I hadn't heard that. Ever heard of 2nd hand smoke? <s>
Cigarette smoke contains 4,000+ chemical compounds - some are harmless, but many are toxic and a few are known carcinogens. Even the so-called "light" cigarettes aren't anywhere near as "safe" as the cig companies would have you believe.
By the way, one of the more interesting debates/arguments I ever had with JVP was over cig companies - I said I'd never ever work for a cig company, not even if they paid me top dollar. He disagreed (and he's not a smoker either)
Every time I see someone smoking in public, every time I see someone driving and flicking the last part of a cigarette out the window, I want to smack them in the face.
