Study Summary

This is a randomized, placebo-controlled, crossover human laboratory study investigating the dose-dependent safety and acute effects of Cannabidiol (CBD) on measures of pain and opioid craving in outpatients with opioid use disorder (OUD) receiving medication-assisted treatment with methadone or buprenorphine. With a duration of approximately 4 weeks, participants will come to the testing site for a total of five times: one initial screening session, and four experimental sessions where study medication, CBD, will be administered, separated by at least 72 hours to limit carryover effects.

Primary Outcome

The SAFTEE is a multi-symptom checklist that has been used successfully in the investigators previous studies to assess and monitor any adverse events and possible side effects of study medications. It includes information regarding the severity of any presenting symptoms (0= none, 1= mild, 2= moderate, and 3= severe), as well as the course of action taken by the study staff in response. The SAFTEE is administered before the administration of CBD at baseline, (timepoint -30 minutes) and 4 hours
