Question

Quizplus · Accepted Answer

Current research shows that infants born to mothers who smoked during pregnancy weigh an average of one-half pound less at birth. Therefore, pregnant women should quit smoking to prevent this complication. While nicotine is addictive, smoking during pregnancy has not been specifically linked to mental retardation. Infants born to smoking mothers are at increased risk for respiratory and lung problems, but not necessarily heart defects.
