接触二手烟是一种重要的可预防的疾病和死亡原因。二手烟会导致成年不吸烟者患肺癌和心脏病，会导致婴幼儿患支气管炎和肺炎等严重疾病，也会导致不吸烟妇女的婴儿出生体重过低和婴儿猝死综合症(SID)。虽然美国在减少二手烟暴露方面取得了巨大进步，但许多成年人和儿童仍处于危险之中。

Secondhand smoke exposure is an important preventable cause of illness and death. Secondhand smoke causes lung cancer and heart disease in adult nonsmokers, serious illnesses such as bronchitis and pneumonia in infants and young children, and low birth weight and sudden infant death syndrome (SIDS) in infants of nonsmoking women. While the nation has made tremendous progress in reducing secondhand smoke exposure, many adults and children remain at risk.
