I haven't puffed on a cigarette for over 25 years! When I was a smoker, I was lighting up every 10-15 minutes. Yep, I was a chimney. And, if anyone looked cross-eyed at me cause my smoke bothered them, I'd blow my 2nd hand fumes into their face and tell them to 'suck my Bic!'  Smokers are an entitled, mean bunch. Today's tobacco puffers are even more dangerous, cause at ten to thirteen dollars a 'pack', you can see why!
