Stimulant use during pregnancy is associated with which complications?

• A. Gestational diabetes
• B. Hypertension
• C. Placental insufficiency, abruption, and hemorrhage
• D. Preeclampsia

Answer: (C)

Stimulant use during pregnancy damages placental blood flow because these drugs cause strong vasoconstriction of uteroplacental vessels. That reduced placental perfusion sets up placental insufficiency and makes the placenta more prone to premature separation, i.e., placental abruption, which can lead to vaginal or uterine hemorrhage. These placenta-related issues are the most characteristic and well-documented complications of fetal exposure to stimulants like cocaine and methamphetamine. While stimulant use can contribute to higher maternal blood pressure and may be associated with hypertensive disorders, the direct vascular effects on the placenta leading to insufficiency, abruption, and hemorrhage are the clearest and most specific complications. Gestational diabetes is not a typical consequence of stimulant exposure, and although hypertension or preeclampsia can occur, the placenta-specific problems described are the strongest link.
