>>One thing in cigarettes that they don't disclose is a fair amount of benzene.<<

They released a partial list some years ago, if I remember correctly and I think benzene was on that list. I think acetone was too. I mean, THAT's what they told us about. I can only wonder what they still decided to keep secret because benzine and acetone are two EXTREMELY toxic substances. Hell, nicotine is one of the most powerful poisons known to man.
