Significant Psilocybin studies

Significant Psilocybin studies

2006 - mystical type experiences

Psilocybin can cause mystical experiences very similar to those reported occurring spontaneously by mystics throughout history. Most participants described them as being among the most personally meaningful and spiritually significant of their lives.

2011 - positive effects in healthy people

Psilocybin administered to healthy persons was recognized to be pleasurable, enriching and non-threatening. Negative effects can be mitigated by interpersonal support.

2015 - treating addiction to alcohol

Psilocybin shows great promise, treating addiction. For alcoholism, it seems results (enduring abstinence) are tied to the intensity of experience.

2016 - challenging experiences

Although counting among the safest of substances, mushrooms can produce challenging experiences. However, 84% of people in hindsight endorse these expereinces to have been greatly beneficial to their lives.

2017 - smoking addiction

Psilocybin shows great promise in addiction treatment.
12 months after the experience, 67% of participants were completely smoke-free, while 86.7% rated the experience as among the most meaningful of their lives.

2017 - therapeutic mechanism: creative thinking, empathy, well-being

Consumption of magic mushrooms in a retreat setting may help bring about a shift of consciousness over time, from separation to connection.
Creative thinking, empathy and life satisfaction were all perceived as improved in the following week.

2018 - nature connection

During a study testing the efficacy against treatment-resistant depression participants noted that they were feeling more connected to nature up to a  year later.  They also noted feeling less prone to authoritarian views.

2018 - treatment-resistant depression

Efficacy of psilocybin against severe, uni-polar, treatment-resistant depression, in combination with psychological support: 31% of participants reported anti-depressant effects 6 months after the experience.
No patients sought conventional antidepressant treatment within 5 weeks of psilocybin.

2018 - combination with spiritual practices

Psychedelic integration especially paired with spiritual practices like meditation or journaling causes enduring shifts in prosocial values and behaviour, while promoting healthy psychological functioning.

2020 Psilocybin and existencial anxiety

In 3 seperate studies, existential anxiety in terminally ill cancer patients seems to be mitigated by a single psilocybin experience, with benefits highly enduring. A follow-up study of surviving NYU participants conducted four and a half years later reported sustained antidepressant and anti-anxiety effects, with participants considering their experiences as among the most deeply profound of their lives.
