Exposure to Secondhand Smoke Can Lead Preteens to Nicotine Addiction

A new study has found that exposure to secondhand smoke increases the risk of nicotine dependence in non-smoking preteens. The study, by researchers from Concordia University and the University of Montreal, also found that preteens who repeatedly observe a parent, sibling, friend, or neighbor smoking cigarettes are more likely to become smokers themselves in adolescence.
