What substance use has been associated with an increased risk of Abruptio Placenta?

Cocaine use has been associated with an increased risk of Abruptio Placenta due to its stimulant effects on the cardiovascular system. Cocaine can cause vasoconstriction and increase blood pressure, which can lead to increased uterine tone and reduced uteroplacental blood flow. This disruption of normal blood flow can precipitate an abruption, where the placenta detaches from the uterine wall, leading to potential complications for both the mother and the fetus.

Other substances, like alcohol, marijuana, and heroin, have their own risks and complications during pregnancy, but cocaine is particularly linked to Abruptio Placenta due to its direct effects on blood vessels and uterine contractions. This understanding is critical when discussing substance use and its implications for maternal and fetal health in clinical settings.
