Dr. Caplan’s Clinical Pearl
 

If you’re trying cannabis for sleep or pain, bring your medication list to a clinician who understands cannabinoid medicine. THC can add to the sedation from other drugs, and CBD can change how your body processes certain prescriptions. A useful consultation should leave you with a cautious starting plan and a clear way to judge whether it’s helping.
