Question

Quizplus · Accepted Answer

Fetal alcohol syndrome is the third-leading cause of birth defects in the United States, caused by the mother consuming alcohol during pregnancy. Cigarette smoking and marijuana use can also lead to birth defects, but they are not ranked as high as fetal alcohol syndrome. HIV from sharing needles is not a cause of birth defects, but can lead to transmission of HIV from the mother to the baby during pregnancy or delivery.
