Smoking during pregnancy can cause several adverse effects. Carbon monoxide and nicotine, the main ingredients responsible, mediate their effects by decreasing the availability of oxygen to the fetus and placenta. A strong association occurs between cigarette smoking and lower birth weight. The mean birth weight of infants of women who smoke during pregnancy is about 200 g less than that of infants of nonsmokers. Smoking is also associated with a higher incidence of preterm premature rupture of membranes, placental abruption, and placenta previa, and risk of infant death from sudden infant death syndrome.
