Smokers should be free to smoke wherever they want, as long as I can have to right extinguish their smoke without incurring censure, i.e. getting a slap in the face. And of course I should have the right to require business owners to install air handling equipment that would prevent me from inhaling any of the smoke already there. I look at smoking this way; someone has every right to own a gun but they can't walk into Walmart and shoot at the manikins for "practice".
