The Health Consequences of Involuntary Exposure to Tobacco Smoke (2006)

Pack of cigarettes displaying the Surgeon General's Warning

This Surgeon General's Report finds there is no risk-free level of exposure to secondhand smoke. This means that being around any amount of secondhand smoke is harmful. Major findings include:

  • In nonsmoking adults, secondhand smoke exposure increases the risk of getting heart disease by 25 to 30 percent and lung cancer by 20 to 30 percent.
  • In infants and children, secondhand smoke exposure can cause sudden infant death syndrome (SIDS), breathing problems, ear infections, and asthma attacks.
  • Nearly half of all nonsmoking Americans are regularly exposed to secondhand smoke.
  • Even brief secondhand smoke exposure can cause immediate harm.
  • Even the best ventilation systems cannot completely eliminate secondhand smoke exposure. The only way to fully protect nonsmokers from secondhand smoke is to eliminate smoking indoors.
