Ok I just have to reply to this one. I am a smoker. and I love to have a smoke, and a drink when I am out....
BUT...
Up here in Massachusetts the ban has now been in full effect for a couple of years, and I have to tell you, I am GLAD they banned the smoking inside. The rooms are clearer, my eyes last longer during the long matches and late nights. A lot of the places are adding outdoor patios! What is really nice is in between matches, is to grab your brew, have a friend watch your gear, walk outside in the clear air and light up. Clears the head, clears the mind, and can get you ready for the next game in a hurry.
I have to honestly change my opinion from my past comments. I think the ban is all right as long as the places make some sort of designated spot for the smokers, and I think that as long as everyone is accomodated and comfortable, then it shouldn't effect the game of pool that much.
I think the lack of media attention and public interest is the worst culprit.
