They won't because it is nice for some to have a scapegoat and bogeyman for posing to be health gurus whilst serving and/or scoffing down pints and bags of chips. I do notice that whilst they whip on the smokers that nobody seems to want to ban the product itself, though, to solve the problem at it source, so to speak. Smelling billions in ever-increasing tax revenue of tobacco seems to override the smell (and health concerns) about smoke. They don't seem to care about the side-effects either, like country pubs slowing down or folding, late night loitering and noise and misconduct outside establishments, butts tossed and piling up, increasing the number of smokers overall with new socialising habits, and other side effects as it has in Ireland and Scotland , etc. It's a troublesome side of human nature that some just love to tell others what to do and/or nanny them.
