For those posters who are trying to quit, you have my fullest support. Good luck. I wish you success.
I have never smoked cigarettes and only a few dozen cigars in my youth.
I have played in live poker rooms in New York, Arizona, Nevada, California, West Virginia, and Ontario (Canada). Not one of the rooms allowed smoking. In some casinos players get only a 5 minute break for a smoke or call of nature.
Casinos in Ontario, Canada don't even allow smoking inside - period. The air is fresh and clean, unless you are unlucky and sit beside a smoker who has just returned from the outdoor smoking pit.
I also play in a home game, where the only smoker is the home owner. He always goes outside to smoke.
