According to the National Center for Complementary and Integrative Health (NCCIH), research suggests that psilocybin (the active compound in “magic mushrooms”) may have potential benefits for certain mental health and addiction conditions when used in controlled clinical settings, typically alongside psychotherapy. The NCCIH emphasizes that research is still ongoing and that evidence is not yet conclusive.
Potential Benefits Reported by NCCIH
- Alcohol Use Disorder: A 2022 study found that psilocybin-assisted psychotherapy was associated with fewer heavy drinking days over a 32-week period compared with psychotherapy plus placebo, suggesting potential benefit for alcohol use disorder.
- Anxiety and Existential Distress in Serious Illness: Small studies involving people with life-threatening illnesses, such as advanced cancer, found that psilocybin combined with psychotherapy may help reduce anxiety, depression, and existential distress while improving quality of life. NCCIH notes that these studies had important limitations.
- Depression: Research reviewed by NCCIH suggests that psilocybin combined with psychological support may reduce symptoms of depression in the short to medium term. A 2023 analysis found improvements lasting up to five weeks, and another study reported rapid reductions in depressive symptoms within eight days, with benefits lasting about six weeks.
Important NCCIH Caveats
NCCIH also stresses that:
- The evidence is still developing and many studies are small.
- Benefits have generally been observed when psilocybin is administered with professional psychological support.
- Psilocybin can cause serious adverse effects and is not considered safe for everyone, particularly people with certain psychiatric conditions.
- It remains illegal under U.S. federal law, although state laws vary.
So, as summarized by NCCIH, the main potential benefits currently being investigated are improvements in depression, anxiety and distress related to serious illness, and alcohol use disorder, but more research is needed to determine long-term effectiveness and safety.
