Could a single dose of psilocybin help people break free from opioid addiction?

NCT ID NCT06067737

First seen Jul 17, 2026 · Last updated Jul 17, 2026

Summary

This study tests whether a single high dose of psilocybin (the active ingredient in magic mushrooms) can help people with opioid use disorder stay off illicit opioids when added to standard buprenorphine treatment. About 90 adults who have already started buprenorphine will receive either a high dose (30 mg) or a very low dose (1 mg) of psilocybin in a controlled setting. Researchers will track opioid abstinence, treatment retention, and quality of life over 8 weeks to see if psilocybin provides an extra benefit.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance
a single high dose (30 mg) of psilocybin, compared to a very low dose (1 mg), given alongside standard buprenorphine treatment
What this could lead to
If it works, this could point toward a new way to boost the effectiveness of standard opioid-use-disorder treatment, helping more people stay off illicit opioids and improve their quality of life.
What could go wrong
This is a mid-stage trial with only 90 participants, so results may not apply to everyone. The high dose of psilocybin can cause intense psychological effects, and it is unknown whether any benefit will last beyond the 8-week follow-up.
