Continuing coverage: According to a new UTMB study, two fifths of never-smoking adolescents are exposed to secondhand smoke. A total of 356,414 never-smoking adolescents from 168 countries participated in the study. “We found that the odds of secondhand smoke exposure for never-smoking teens exposed to both parents and peers who smoke is 23 times higher than that of never-smoking teens who don’t have smokers often around them, said Phani Veeranki. "Our findings provide evidence for policy makers and public health professionals about the need for smoke-free environments in places frequented by teens worldwide.”
