Answer

Cigarette smoking increases a patient's overall risk of placental abruption. [7]

A prospective cohort study showed the risk of abruption to be increased by 40% for each year of smoking prior to pregnancy.

In addition to the increased risk of abruption caused by tobacco abuse, the perinatal mortality rate of infants born to women who smoke and have an abruption is increased. [8, 9]
