So, what about Third hand smoke? Third hand smoke? What the heck is that? Is the even possible? So, wait, I'm breathing the remnants of someone's second hand smoke? Like, you smoke, Bob breathes that and I breath Bob's exhalation? Is that what we're talking about?
Sort of... but not quite. Third hand smoke is residual smoke. Researchers have found that this residual tobacco smoke, now being called "thirdhand smoke," is a combination of cigarette smoke and things like indoor pollutants like ozone and nitrous acid. When mixed with the cigarette smoke it creates a new compound. Thirdhand smoke also mixes and settles within the dust, it'll find it's way down to the carpet, the furniture, start hanging out of the curtains. Worst of all it gets into deep into porous material, think paneling and drywall. It also lingers on the hair, skin, clothing, and fingernails of smokers. Consider it this way, you don't want to smoke in front of your Grandkids, so you have smoke outside. You also smoke in the car. But, as soon as you pick that kid up or put your grandson in your car, you're exposing him to thirdhand smoke. These compounds created by the blending of cigarette smoke and other inhalants and particles in the air are not easy to clean up, they have a very long life of their own, and many may be carcinogenic. This is probably the real reason they tear down casinos in Vegas.
