So don't let them smoke in your house, and don't go their house. The smell of smoke on their clothes isn't going to hurt you. Honestly, you're being a bit hysterical about it if you won't allow a loved one near your kids because they smoke. BTW, never hang around a welder if that's the case, or anyone who works in the oil patch, or Anna's hubby, he's the worst... firemen... their whole job is smoke, and nasty toxic smoke to boot. Don't sit around a camp fire. And for the love of god, don't drive a car. And make darn sure your kids enver live within a 15 city block radius of a gas station btw... that's a huge cancer risk that your smoky smelling mom could never come even remotely close to equalling.
