Background: There is a wealth of research evidence on the adverse effects of smoking prior to and during pregnancy. Smoking in pregnancy increases the risk for preterm birth, small-for-gestational-age babies and fetal anomalies often associated with poor placental perfusion and placental insufficiency. Smoking also has significant long-term health implications for mothers and families. Both pharmacological and psychosocial smoking cessation interventions have been shown to be effective for pregnant women.
