I am not a smoker but I think the smoking/non-smoking sections in restaurants have worked out just fine. I do have two friends who are actually allergic to smoke and end up wheezing bigtime if they spend too much time in a bar where their is not a non-smoking section. So, I can see both sides.
This is really a private property issue. Businesses has proven that they can accomodate both smokers and non-smokers. That being said, I think that governmental entities are within their right to prohibit smoking in public buildings.
No arguement-- I stopped smoking a month ago. The taxes are liberals' way to hit smokers only because they are a minority group. If they all stopped buying cigs at the local places and roll own or get elsewhere these libs would be screaming.
