Second hand smoke is the real deal. Very bad.
Secondhand smoke causes approximately 3,400 lung cancer deaths and 22,700-69,600 heart disease deaths in adult nonsmokers in the United States each year.... Secondhand smoke is responsible for between 150,000 and 300,000 lower respiratory tract infections in infants and children under 18 months of age, resulting in between 7,500 and 15,000 hospitalizations each year, and causes 1,900 to 2,700 sudden infant death syndrome (SIDS) deaths in the United States annually.

U.S. Surgeon General Richard H. Carmona today issued a comprehensive scientific report which concludes that there is no risk-free level of exposure to secondhand smoke. Nonsmokers exposed to secondhand smoke at home or work increase their risk of developing heart disease by 25 to 30 percent and lung cancer by 20 to 30 percent. The finding is of major public health concern due to the fact that nearly half of all nonsmoking Americans are still regularly exposed to secondhand smoke.
