I don't smoke in cars or indoors, and I rarely smoke in public. So laws banning these things won't affect me personally. What I worry about, as I sit on my front porch smoking a pipe and writing this, is laws prohibiting smoking on private property within X feet of a public road (for fear that a jogger may catch a "whiff" of my smoke and die).
Ironically, my woodstove gives off more pollutants than the few pounds of tobacco I smoke each year. So does my car. So probably does my grill. Methinks they're "missing the moon for sixpence", as Somerset Maugham might say.
Incidentally, when I was a kid riding in my Grandparent's car, I would much rather smell my Grandfather's smoke than my Grandmother's perfume! (Gram's perfume was so strong it probably drove my Grampa to smoke in the car).
Someday it may come to pass that tobacco farmers figure out that they can make more money growing something other than tobacco. Then the fun begins!
