Researchers at Wake Forest University School of Medicine have found high rates of second-hand smoke among American college students. Of 4,223 undergrads, 83 per cent had been exposed to SHS at least once in the preceding seven days, usually at a restaurant or bar, at home or in a car. Binge-drinkers were even more likely to report SHS exposure. “We were really kind of floored to see how many, and how frequently, students are exposed to it,” said one of the study’s authors. The study appears online in the July 23 issue of Nicotine & Tobacco Research.
