What is Secondhand Smoke, and How Does it Affect Indoor Air Quality?
Secondhand smoke is defined as the involuntary inhalation of smoke from burning tobacco products, such as cigarettes, cigars, or pipes, as well as the smoke exhaled by smokers. It contains over 7,000 chemicals, many of which are toxic, and at least 70 of these are known to cause cancer. The U.S. Environmental Protection Agency (EPA) classifies secondhand smoke as a Group A carcinogen, indicating it is a known cause of cancer in humans.
According to the World Health Organization (WHO), there is no safe level of exposure to secondhand smoke, which poses significant health risks not only to smokers but also to non-smokers who are exposed to it.
