An OB Addiction Specialist Explains Why Marijuana Is Not Benign In Pregnancy

THC isn’t the same drug it was 20 years ago, and pregnancy counseling hasn’t caught up. We sit down with Dr. Nazanin Amadieh, a board-certified OBGYN who also trained in addiction medicine, to map what today’s high-potency cannabis means for conception, the placenta, fetal development, and the newborn period. If you’ve heard “it’s legal” or “it’s just a plant” as proof of safety, this conversation offers a clearer, evidence-informed way to think about marijuana during pregnancy without stigma and without hand-waving. We dig into the endocannabinoid system, why fetal receptors show up as early as five to six weeks, and how cannabis exposure may affect implantation, placenta formation, and early brain development. Then we get practical about the outcomes clinicians track: miscarriage risk signals, the stronger association with low birth weight or small for gestational age babies, and what NICU admission can mean for families. Because so much research is dated and modern THC concentrations can reach levels older studies never measured, we also talk openly about uncertainty and why “no proof of harm” is not the same as “safe.” Nausea and vomiting gets its own spotlight, including the tricky overlap between hyperemesis gravidarum and cannabinoid hyperemesis syndrome, plus the hot shower clue that can point toward CHS. We also cover breastfeeding and THC in breast milk, what parents should watch for, and why postpartum relapse to cannabis is common when anxiety and overwhelm hit after the first few months. If you care about maternal health, prenatal care, addiction medicine, or harm reduction, you’ll leave with better questions and clearer next steps. Subscribe, share this with someone who’s pregnant or caring for pregnant patients, and please leave a review so more people can find the show.To contact Dr. Grover: [email protected]
