Tobacco exposure

Tobacco exposure refers to coming into contact with substances from tobacco products, such as cigarette smoke or chewing tobacco. This exposure introduces harmful chemicals into the body, increasing risks of health problems like lung disease, heart disease, cancer, and respiratory issues. Even secondhand smoke—when someone nearby is smoking—can affect non-smokers, especially vulnerable groups like children or those with existing health conditions. Reducing tobacco exposure through cessation or avoiding environments where tobacco is used significantly improves overall health and lowers the risk of serious illness.
