Psilocybin for Substance abuse disorder

Based on 11 papers

Research on psilocybin for treating substance use disorders is promising but still early. Reviews and small studies suggest psilocybin and similar psychedelics can reduce drug or alcohol use for some people. However, most trials are small, and scientists are still figuring out how much the drug itself does versus the therapy around it (preparation and integration). Benefits seen in studies include large but preliminary improvements that sometimes last months. Risks include strong hallucinations and, in rare cases, lasting perceptual problems or worsening mental-health symptoms in vulnerable people. Many experts say more large, careful trials are needed and that therapy methods and safety rules must be standardized.

Key findings

  • Some reviews report that psilocybin and other classic psychedelics have shown promise in reducing substance use and other mental-health problems in early studies. 15059 15086 15063
  • Most positive findings come from small or early-stage trials and review articles. Large, definitive clinical trials are still limited. 15064 15063 15086
  • Psychedelic-assisted therapy always includes preparation, supervised drug sessions, and follow-up therapy. Good preparation is widely seen as important for safety and outcomes. 15065 15063 15086
  • Researchers do not fully agree on how these treatments work. Some data point to the intense psychological experience people have during the drug session. Other work points to changes in brain circuits and plasticity (how brain cells rewire). 15086 15059
  • Observed benefits sometimes last for months after a single or a few drug-assisted sessions in trials of psychedelics for other conditions. This suggests possible lasting effects for substance problems too, but direct evidence in large substance-use trials is still sparse. 15086 15063 15059
  • There are clear risks. Psilocybin and similar drugs can cause strong hallucinations and changes in perception. In some people these effects can be severe or long-lasting. 15080 15086
  • Experts and therapists are cautious. Many counselors see promise but want more research and prefer medical supervision if these treatments are used. 15057 15087
  • Other related compounds are being explored for alcohol problems. For example, early reviews suggest 5‑MeO‑DMT produces intense short experiences and is being studied as a possible treatment for alcohol use disorder, but that work is still preliminary. 15122
  • Broader issues slow clinical use. These include changing laws, the emerging psychedelic industry, and the need for standard rules about how to run therapy and make treatments safe and fair. 15079 15087 15065

Counselors’ attitudes toward psychedelics and their use in therapy

Benjamin Hearn, Michael D. Brubaker, George B. Richardson

Researchers surveyed counseling professionals about psychedelics and psychedelic‑assisted therapy. They found that counselors had mixed feelings overall, but were more accepting when use was medically supervised. Most counselors said these therapies show promise and that more research is needed. The study matters because drugs like MDMA and psilocybin may soon…

The potential of 5‐methoxy‐N,N‐dimethyltryptamine in the treatment of alcohol use disorder: A first look at therapeutic mechanisms of action

Addiction Biology Summary & key facts 2024 11 citations

This paper is a first look at whether the fast-acting psychedelic 5‑MeO‑DMT might help people with alcohol use disorder. The authors reviewed existing studies in humans and animals and found early signs that 5‑MeO‑DMT can cause intense mystical feelings and a loss of self-boundaries, and that it changes brain rhythms…
