Exploring the use of psilocybin to help with stress-related relapse in addiction

Therapeutic potential of psilocybin on stress-cued reinstatement

NIH-funded research Medical University of South Carolina · NIH-11165933

This study is looking at how psilocybin, a substance found in certain mushrooms, might help people with opioid use disorder and PTSD by reducing stress that can lead to relapse, and it aims to find safer ways to use it for treatment.

What this research studies

This research investigates the potential of psilocybin, a classic psychedelic, to reduce stress-induced relapse in individuals with opioid use disorder (OUD) and post-traumatic stress disorder (PTSD). The study aims to understand how psilocybin affects the brain's response to stress and addiction, using a novel mouse model to simulate relapse triggered by stress cues. By examining the neural mechanisms involved, the research seeks to develop effective treatments that minimize the hallucinogenic side effects typically associated with psychedelics. If successful, this could lead to new therapeutic options for patients struggling with these challenging conditions.

Who could benefit from this research

Good fit: Ideal candidates for this research are individuals suffering from opioid use disorder and post-traumatic stress disorder, particularly those who experience stress-related relapse.

Not a fit: Patients who do not have opioid use disorder or post-traumatic stress disorder may not benefit from this research.

Why it matters

Potential benefit: If successful, this research could provide new treatment options for patients with opioid use disorder and PTSD, potentially reducing relapse rates and improving overall mental health.

How similar studies have performed: Previous studies have shown promising results using psychedelics for treating stress and addiction, indicating that this approach may be effective.
