Explain why environmental tobacco smoke (ETS) is a health hazard
What will be an ideal response?
ETS contains hundreds of toxic chemicals, including more than 70 carcinogens. It is estimated to be responsible for 3,400 lung cancer deaths and 46,000 cardiovascular disease deaths a year in nonsmokers, and increases the risk of sudden infant death syndrome in infants who live with smokers. Secondhand smoke interferes with the normal functioning of the heart, blood, and vascular systems, can cause allergic reactions, headaches, dizziness, and nausea. In adults, ETS is linked not only to lung cancer, but also to throat cancer, cancer of the nasal sinus cavity, and breast cancer. Children exposed to ETS have higher rates of respiratory disease and learning and behavioral disorders, leukemia, lymphoma, and brain tumors.
