Tobacco Smoke

Tobacco smoke is a complex mixture of gases and particles that is produced when a substance, typically tobacco, is burned. This smoke contains hundreds of chemical compounds, including many known to be harmful to human health. Tobacco smoke, including secondhand smoke (SHS) and environmental tobacco smoke, can lead to serious diseases, including lung and heart diseases, cancer, and stroke. Many of these diseases are potentially fatal, making the avoidance of tobacco smoke exposure essential for good health. Strategies for avoiding tobacco smoke include reducing exposure in the workplace and public places, and creating smoke-free homes and vehicles.
