Question

Quizplus · Accepted Answer

Exposure to secondhand smoke can lead to lung damage, and has been linked to a variety of negative health outcomes, including heart disease, lung cancer, and respiratory illnesses. While levels of nicotine and tar may be lower in secondhand smoke than in the smoke produced by a smoker, exposure to secondhand smoke is still harmful. Studies have consistently shown that even brief exposure to secondhand smoke can have negative effects on the health of nonsmokers, particularly children, pregnant women, and individuals with preexisting health conditions.
