Cannabidiol Effects on Craving and Relapse Prevention in Opioid Use Disorder

University of California, Los Angeles·interventional·Posted Dec 26, 2018·Updated Apr 22, 2026

In Brief

A Phase 2 clinical trial evaluating Cannabidiol (CBD) 600 mg and Placebo for Opioid-use Disorder. Completed, enrolled 35 participants across 1 site.

Detailed Summary

This research aims to determine the effects and safety of cannabidiol (CBD) (ATL5 softgel capsules) as an adjunctive therapy for patients who have Opioid Use Disorder and are taking buprenorphine + naloxone or methadone. Buprenorphine + naloxone and methadone is an approved treatment for Opioid Use Disorder, but relapse to opioid misuse is common among patients who receive this treatment. Finding an adjunctive treatment for these patients would be helpful. We will recruit participants from the Tarzana Treatment Center (TTC) in the San Fernando Valley. They will be receiving buprenorphine + naloxone or methadone as part of residential therapy. Potential participants who pass initial screening and wish to continue in the study will provide written, informed consent and will complete a 2-day evaluation, including blood and urine tests, questionnaires about their mood, medical, psychiatric and drug use history and physical exam. Up to 60 participants who meet all eligibility criteria will be invited to complete baseline assessments (blood and urine tests, questionnaires), and will be assigned randomly to receive CBD (600 mg/day) or placebo, corresponding to two groups of up to 30 participants each. After the baseline measurements, participants will take part in a 28-day treatment phase for 4 weeks. They will take the study medication under supervision (CBD 300 mg twice daily or placebo). Questionnaires on opioid craving, withdrawal, and mood symptoms will be administered daily during the treatment period, excluding weekends. After the 28-day intervention, participants will complete the questionnaires and undergo urine drug tests in 4 weekly follow-up visits. The study will last \~10 weeks, comprising three periods: a screening period (2-weeks when participants are stabilized on buprenorphine + naloxone or methadone in residential treatment at the Tarzana Treatment Center), a treatment period (4 weeks when study CBD or placebo is administered at Tarzana Treatment Center), and a follow-up period (4 weeks after termination of the test intervention).

Interventions

Cannabidiol (CBD) 600 mgdrug

CBD (300 mg) will be administered orally twice daily in the morning and again in the afternoon. The active ingredient in the Ananda investigational new drug, ATL5, is cannabidiol (CBD), extracted from hemp, at a 10% strength (softgel capsules with 100 mg/ml of CBD per capsule). The novel formulation is based on the principle that a water-free mixture of some concentrated inactive ingredients (excipients) self-assemble spontaneously into liquid nanodomains that contain the active component CBD. ATL5 Softgel Capsules will be manufactured by Baxco Pharmaceutical Inc. (California, USA) under cGMP conditions.

Placebodrug

The placebo softgel capsule formulation will have a composition with the same relative proportions as the CBD ATL5 Softgel Capsules. This formulation will be manufactured by Baxco Pharmaceutical Inc. under cGMP conditions. The amount (number of softgel capsules) of placebo will be administered to match that of the active compound, daily in the morning and afternoon for each of 28 days.
