Breathing in cannabidiol to test safety in occasional cannabis users

Cannabis

Part of Mental health clinical trials.

This Phase 1/2 study tests whether inhaled cannabidiol (CBD) is safe and well-tolerated in healthy people who use cannabis occasionally. You’d be asked to avoid other cannabis and certain drugs around study visits so researchers can measure your response clearly.
