There's No Question That Secondhand Smoke Changes Your Genes

A new study reveals the true damage of secondhand smoke.


That's it, it's final: Secondhand smoke is bad for your body and actually changes your genes. Researchers at Weill Cornell Medical College tested bodily feedback as people lit up and inhaled nearby smoke and are now telling the world: Your body has a genetic response and your cells actually change, on a molecular level.

The finding is groundbreaking, but how will this influence people's behavior, or more importantly, how will health campaign planners change their targeted messaging to draw upon such imagery to better influence people's behavior?

    My mother got away from using tobacco by switching to an electronic cigarette. It does not expose anyone to smoke, tar, or carbon monoxide because nothing burns. It has an atomizer that warms and vaporizes a nicotine solution. Since she got her starter kit from, she has had no urge to go back to smoking. Even better, she has ceased starting her day with the ritual of an extended coughing fit.
