Need another reason to keep that resolution? A new study published in the January issue of Pediatrics finds that “third-hand smoke” can linger in your hair and clothing long after you’ve extinguished your cigarette. “When you smoke – anyplace – toxic particulate matter from tobacco smoke gets into your hair and clothing,” says the lead study author. "When you come into contact with your baby, even if you're not smoking at the time, she comes in contact with those toxins.” Small children are especially susceptible to third-hand smoke exposure because they’re likely to touch and mouth contaminated surfaces. The study may be used to justify expanded smoking bans in public places. But not everyone’s convinced: 65 percent of nonsmokers believe that third-hand smoke harms children, but only 43 percent of smokers agree with them. “The dangers of third-hand smoke are very real,” insists the study author.
