I remember the days of smokers being allowed to light up in poker rooms. It made the experience pretty awful for almost everyone who was playing.
Most
casinos have a smoking area that one can use when on a tournament break or when taking a break from a cash game. That seems to be a good compromise, I think.
And, given the laws in most jurisdictions, you will not see smoking coming back into poker rooms.
Still, I do understand some smoker's point being; if smoking is legal and is such a cash cow for governments, how can it be so restricted?
I, for one, do not miss the days of going home and needing a shower (or two) to get the smoke out of my skin and hair and needing a sealed laundry hamper for my clothes.
