ResearchPolicySafety Dr. Caplan’s Take “What we’re seeing in the literature is that cannabis has genuine therapeutic value for specific conditions like [chronic pain](https://cedclinic.com/cannabinoids-pain-management-opioid-alternative/) and chemotherapy-induced nausea, but we need to stop pretending it’s a panacea while also acknowledging that dismissing it entirely ignores real patient benefit and leaves people suffering unnecessarily.” Clinical Perspective While balanced media coverage of [medical cannabis](https://cedclinic.com/therapeutic-benefits-of-thc/) acknowledges both potential benefits and harms, healthcare providers should recognize that news summaries often lack the methodological detail needed for clinical decision-making. The evidence supporting cannabis for specific indications like chronic pain and chemotherapy-induced nausea remains mixed and heterogeneous, with most studies limited by small sample sizes, variable dosing protocols, and inability to control for concurrent medications or lifestyle factors. State-level policy changes, as potentially occurring in Tennessee, may outpace the clinical evidence base and create pressure for prescribing before high-quality comparative effectiveness data are available. Providers should maintain awareness of their own state’s regulations while counseling patients that evidence-based alternatives with longer safety track records often remain preferable as first-line treatments, reserving cannabis consideration for carefully selected cases where conventional options have been exhausted or are contraindicated. 💬 Join the Conversation Have a question about how this applies to your situation?
