The webinar discusses the impact of secondhand smoke (SHS) exposure in vehicles, particularly on children, revealing that a significant percentage of youth are exposed while riding with smokers. Research indicates that SHS levels in cars can be dangerously high, often exceeding those found in public smoking areas, emphasizing the urgent need for smoke-free car policies. Recommendations include legislative actions to prohibit smoking in vehicles when children are present and community education on the risks associated with SHS.
