Pregnant women should not smoke. They also should not expose their developing baby to the smoke of others.
The chemicals in secondhand smoke have been linked to an increased risk in low birth weight, stillbirth and other birth defects. The harmful consequences of secondhand smoke continue even after the baby is born. Infants who are exposed to secondhand smoke have an increased risk of sudden infant death syndrome (SIDS), asthma and other respiratory diseases, impaired lung function and middle ear disease.
If you smoke, you should quit. Even if you don’t smoke, you should make sure your baby develops in a smoke-free environment.
The fetuses of mothers who quit smoking by 16 weeks gestation can achieve their full growth potential. Lower exposures to smoke equal improved outcomes.
