Smoking in pregnancy poses a significant health problem for both mother and baby. Many women who smoke will quit by themselves before becoming pregnant and others will stop once their pregnancy is confirmed. For some women, however, considerable help is needed to successfully stop smoking. The research evidence is clear: cigarettes contain multiple harmful substances, and women who smoke during pregnancy are more likely to have babies with birth defects than non-smokers. As smoking in pregnancy adversely affects so many different aspects of health, it remains one of the greatest factors that could potentially improve birth outcomes.
