The thing is with Ohio (or atleast my personal experience) is that I rarely, if ever, saw an establishment that specifically said they were a non-smoking one. If more businesses chose to do this it would be great, but in all reality many of them wouldn't because it usually deters business and really button-holes them as to the amount of potential customers they can have.

Like Baka said it really is a slippery slope and just one of those things that isn't going to have any clear cut agreement on it. But as for the topic, California of all places having these laws is something I don't get.
