Nearly half of American teens who have never used tobacco are exposed to harmful secondhand smoke despite widespread laws banning smoking in public places. An analysis of data from over 18,000 middle school and high school students reveals that 48% reported being exposed to secondhand smoke in 2013. Investigators also found that secondhand smoke exposure was nine times higher among never-smoking teens with no smoke-free rules in their home and car than teens with 100% smoke-free homes and vehicles.
