Surgeon General's Report on
Secondhand Smoke

On June 27, 2006, U.S. Surgeon General Richard H. Carmona 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.

The report, The Health Consequences of Involuntary Exposure to Tobacco Smoke, finds that even brief secondhand smoke exposure can cause immediate harm. The report says the only way to protect nonsmokers from the dangerous chemicals in secondhand smoke is to eliminate smoking indoors.

"The good news is that, unlike some public health hazards, secondhand smoke exposure is easily prevented," Surgeon General Carmona said. "Smoke-free indoor environments are proven, simple approaches that prevent exposure and harm." The report finds that even the most sophisticated ventilation systems cannot completely eliminate secondhand smoke exposure and that only smoke-free environments afford full protection.

The six major conclusions of the Surgeon Generals report are:

1. Many millions of Americans, both children and adults, are still exposed to secondhand smoke in their homes and workplaces despite substantial progress in tobacco control.
2. Secondhand smoke exposure causes disease and premature death in children and adults who do not smoke.
3. Children exposed to secondhand smoke are at an increased risk for sudden infant death syndrome (SIDS), acute respiratory infections, ear problems, and more severe asthma. Smoking by parents causes respiratory symptoms and slows lung growth in their children.
4. Exposure of adults to secondhand smoke has immediate adverse effects on the cardiovascular system and causes coronary heart disease and lung cancer.
5. The scientific evidence indicates that there is no risk-free level of exposure to secondhand smoke.
6. Eliminating smoking in indoor spaces fully protects nonsmokers from exposure to secondhand smoke. Separating smokers from nonsmokers, cleaning the air, and ventilating buildings cannot eliminate exposure of nonsmokers to secondhand smoke.
