Then we've already lost. I fail to see how me enjoying a pipe in the middle of a park or a designated smoking area in an indoor facility with proper air filtering rightfully bothers anyone. I'm curious. Why are you concerned with your children never being exposed to smoke? If you buy that second hand smoke is lethal or dangerous, then you must buy that third hand smoke (i.e. residue on clothes, hair, skin, walls, etc) from you is lethal or dangerous to them.But if the cost of never having to smell cigarette smoke, and more importantly, never have my children exposed to it when we're going about our business is to ban all smoking in public indiscriminately- I'm okay with that.
