How Does Secondhand Smoke Affect Pregnancy?
Secondhand smoke (also called passive smoke or environmental tobacco smoke) is the combination of smoke from a burning cigarette and smoke exhaled by a smoker.
The smoke that burns off the end of a cigarette or cigar actually contains more harmful substances (tar, carbon monoxide, nicotine, and others) than the smoke inhaled by the smoker.
Babies and children exposed to secondhand smoke may also develop asthma, allergies, more frequent lung and ear infections, and are at higher risk for sudden infant death syndrome (SIDS).
