CB1/CB2 physiology, genetic variation, and clinical dosing insights for physicians. --- ✦ New CED Clinical Relevance #67 Notable Clinical Interest Emerging findings or policy developments worth monitoring closely. THCResearchNeurologySafetyMental HealthDosingIndustry Dr. Caplan’s Take “While the [endocannabinoid system](https://cedclinic.com/endocannabinoid-system-fear-extinction/) is a legitimate area of neuroscience research, many of the ‘facts’ circulating online about THC lack the human clinical evidence needed to guide [patient care](https://cedclinic.com/cannabis-cardiovascular-risk-impact/), so I encourage people to distinguish between what we know from controlled studies versus what remains fascinating but preliminary neurobiology.” Clinical Perspective 💊 While educational content about THC’s mechanisms, including its interaction with the [endocannabinoid system](https://cedclinic.com/endocannabinoid-system-fear-extinction/), can help demystify cannabis for both patients and providers, such public-facing materials often lack the clinical nuance needed for medical decision-making.

Healthcare providers should recognize that patient knowledge increasingly comes from diverse online sources, some of which may emphasize [cannabis benefits](https://cedclinic.com/cannabis-and-sexuality-benefits-intimacy/) while downplaying risks or acknowledging gaps in evidence. When patients reference such materials during clinical encounters, providers have an opportunity to contextualize this information within established evidence, discuss potential harms alongside mechanisms of action, and clarify what is known versus unknown about clinical 💬 Join the Conversation Have a question about how this applies to your situation?
