This really isn't your business is it?
It will be the tort courts which will reduce smoking to a small fraction of what we have now. Any employee of private smoking establishments who gets a lung disease or any smoking related illness can sue them into oblivion so allowing private businesses to allow smoking is not too likely.
And don't you know the second hand smoke isn't the killer that the anti's want you to believe? I wish you would keep up with the news more.
I haven't made it my business.
Second hand smoke is not harmless. Particularly when constantly exposed to it. I speak from my own experience with it. Any time it is prevalent and I am exposed I have consequences the next day.
