Now You Have to Worry About Thirdhand Smoke, Too
Study: It settles into everything, damages DNA

(Newser) – Smoking is bad, inhaling secondhand smoke is bad, and now the trifecta: Thirdhand smoke can mess up your DNA. Thirdhand smoke? It's the residue that lingers everywhere—in carpets, in dust, in drapes, you name it—long after a smoker has left a room, explains Science Daily. And now researchers at the Lawrence Berkeley National Laboratory have found for the first time that it causes genetic damage.

"This is the very first study to find that thirdhand smoke is mutagenic," says a study co-author. "Some of the chemical compounds in thirdhand smoke are among the most potent carcinogens there are." It gets worse with this double-whammy, one that poses an especially serious risk for kids: Thirdhand smoke appears to get more dangerous the longer it sits, and it's virtually impossible to eliminate through normal cleaning and vacumming. If you move into a home used by a smoker, another of the researchers suggests replacing the carpets and busting out the paint.

Just smoke and avoid all this nonsense. One of the few truly American industries left.

If you clean the carpets professionally and paint the walls the house will be fine. The air we breath is worse than 3rd hand smoke. As a matter of fact if you have an A/C unit all your ducts would be permeated with smoke too. And if any leaked into the attic the exposed wood and insulation can absord the smoke. And lets not forget the wood floors. Why don't you just tear down the house. And as far as changing your DNA, alchohol does that as well as most everything you breath and injest. It's called evolution.
