On this episode of 716 Together, host Tammie Lee Demler sits down with Dr. Michael Merrill to unpack a major new JAMA study examining cannabis use among adolescents. Together, they explore how marijuana—especially today’s high‑potency products—may increase teens’ long‑term risk for psychosis, bipolar disorder, depression, and anxiety. Dr. Merrill breaks down brain development, the endocannabinoid system, common misconceptions, and the challenges parents face in recognizing and addressing substance use. The conversation also touches on cultural attitudes, honesty in healthcare, and practical guidance for families seeking support. A thoughtful, accessible look at what every parent and caregiver should know.
