This study contributes to the growing body of research examining whether prenatal cannabis exposure affects cognitive development, informing risk-benefit discussions with pregnant patients. Dr. Caplan’s Take “I need to see the actual study data before drawing clinical conclusions. Headlines about prenatal [cannabis safety](https://cedclinic.com/respiratory-effects-inhalational-marijuana/) require careful scrutiny of methodology, particularly how exposure was measured and what cognitive domains were assessed.” Clinical Perspective 🧠 Clinicians should await peer-reviewed publication details before modifying prenatal counseling practices. Current evidence remains mixed on prenatal cannabis effects, warranting individualized risk discussions with pregnant patients. Any counseling should address known risks while acknowledging evolving research landscape. 💬 Join the Conversation Have a question about how this applies to your situation?
