Secondhand Smoke Facts
Secondhand smoke is tobacco smoke that is breathed in by someone who is not smoking themselves. It occurs when a person is in the vicinity of a person who is smoking. Secondhand smoke is a mixture of the smoke from the tobacco product itself (termed sidestream smoke) and exhaled smoke from the smoker (known as mainstream smoke).
The same chemicals, toxins, and cancer-causing substances are present in secondhand smoke as in active smoking; the person who inhales secondhand smoke is exposed to the same toxins as the smoker. Secondhand smoke is known to carry definite health risks for both adults and children. An increased risk of lung cancer is just one of the hazardous health effects of secondhand smoke.
Secondhand Smoke Causes
Any tobacco product has the potential to cause dangers due to secondhand smoke, but cigarettes are the most common sources of secondhand smoke. Exposure to secondhand smoke can occur in the home, workplace, or in public places. Children exposed to secondhand smoke in the home are at particular risk for health problems related to tobacco smoke, as are nonsmokers who reside with smokers.
