1. Placenta Abruption

This condition is where the placenta pulls off the wall of the uterus either before or during labor, necessitating an immediate delivery, usually via cesarean section. A smoker's placenta is thinner, making it more susceptible to an abruption.​​ More on placental abruption.

2. Placenta Previa

Again because of the smoker's thin placenta, it is more likely to cover the mouth of the uterus, the cervix - placenta previa.

This can cause bleeding during the pregnancy. It also makes vaginal birth dangerous and a cesarean becomes necessary due to the risk of hemorrhage of mom and baby.​ More on placenta previa.

3. Sudden Infant Death Syndrome (SIDS)

Babies born to mothers who smoke are more likely to die from sudden infant death syndrome (SIDS).

4. Preterm Labor

If you smoke your body is more likely to try to end your pregnancy sooner by placing your in premature labor in an effort to protect your baby from the harmful side effects of smoking. The problem? Babies born even slightly prematurely have a greater risk of death and other complications. The sooner the baby is born, the more likely you baby is to die or have serious complications, including mental retardation and cerebral palsy.​ More about preterm labor.

5. Stillbirth

Smoking during pregnancy increases the risk of your baby dying during your pregnancy.​ More about stillbirth.

6. Low Birth Weight

Birth weight is an important factor in your baby's health. The smaller the baby, the more at risk for many problems. In fact, low birth weight is one of the top reasons for babies to be ill and die in the first months of life.​ More about low birth weight.
