THC and CBD for opioid addiction and chronic pain

Combination of THC and CBD as a Novel Treatment for Co-Occurring Opioid Addiction and Chronic Pain

NIH-funded research Yale University · NIH-11371353

This project seeks to reduce both chronic pain and opioid cravings in people with opioid use disorder who are receiving opioid agonist therapy by using a combination of THC and CBD.

What this research studies

If you join, you'll receive combined doses of THC and CBD during supervised lab visits while staying on your usual opioid agonist medication. Researchers will measure your pain sensitivity with standardized quantitative sensory tests and track your opioid cravings using a visual cue task. The team wants to see whether CBD can lower cue-induced craving and whether adding THC provides extra pain relief while CBD may limit THC’s side effects. Sessions will be monitored for safety and tolerability at Yale.

Who could benefit from this research

Good fit: Adults with opioid use disorder who also have chronic pain and are currently receiving opioid agonist therapy (for example, methadone or buprenorphine) would be the ideal candidates.

Not a fit: People without opioid use disorder, those not on opioid agonist therapy, pregnant individuals, or anyone with medical or psychiatric contraindications to cannabinoid use may not benefit or be eligible.

Why it matters

Potential benefit: If successful, this approach could offer a single treatment that eases chronic pain and reduces opioid craving, potentially improving recovery and lowering overdose risk.

How similar studies have performed: Previous studies suggest THC can reduce pain and CBD can reduce cue-induced opioid craving, but the combined effects in people with both OUD and chronic pain are largely untested.
