College students up in smoke

It’s no secret that smokers put themselves at risk for health problems. But many people don’t realize the deadly reality of secondhand smoke—and college students are especially vulnerable. Researchers at the Wake Forest University School of Medicine surveyed 4,223 college students from 10 North Carolina universities and found that 83 percent of students were exposed to secondhand smoke at least once in the week before the survey. Among other factors, increased exposure was linked to living in residences where smoking was allowed or places associated with smoking, such as Greek houses or off-campus homes. To reduce students’ risk, say study authors, administrators should enact smoke-free campus policies and offer services to help students kick the habit.
