Third-hand smoke just as dangerous as actually smoking?

Smoking killsFirst-hand smoke exposure is the smoke inhaled by the actual smoker, and second-hand smoke exposure is when others inhale the exhaled smoke. But according to new research, third-hand smoke exposure could be just as dangerous as first- and second-hand smoke.

Third-hand smoke exposure is exposure to surfaces that have been contaminated with second-hand smoke. When a smoker moves out of a house, surfaces and dust can remain contaminated. As time goes on, nicotine is re-emitted from the contamination, and nicotine exposure can approach the levels of first-hand smoking.

Mice exposed to third-hand smoke were hyperactive, experienced significant lung and liver damage, and their wound healing abilities were reduced. In addition to these findings, it was found that third-hand smoke exposure can lead to type II diabetes!

What does this mean for you? Well, it might be more important than you think to choose a hotel that prohibits smoking and pay more attention to the smoking habits of previous owners of your new homes and automobiles. While a lingering odor of smoke might dissipate over time, the lasting effects may not. If you’re still smoking, here’s another great reason to consider the effects you may be having on your kids, your friends’ kids, and those who will be here long after you are.
