Nonetheless, both treatments were effective, and the study may have been underpowered to detect small differences. The inclusion criteria were based on research articles that focused on psychological treatment of depression supplemented with psilocybin. Those treatments were conducted in any population, in either English or Spanish, and without a date limit, as it is considered relevant to include all scientific evidence in a timeless manner, and without restrictions on the type of clinical trial. Documents such as theses, reports, book chapters, study protocols, descriptive articles, and reviews of other articles were excluded, as well as those that did not use the substance for therapeutic purposes and those based solely on pharmacological treatment.

Data Availability Statement

As stated above, it is possible that psilocybin’s antidepressant effect is mediated through rapid activation of 5-HT receptors other than those involved in the psychedelic experience. This raises the possibility of blocking the psychedelic experience by co-administering 5-HT2A antagonists, like ketanserin or risperidone, without impeding the antidepressant therapeutic effect. More research is needed to explore this possibility and better understand the relationship among serotonin receptors, psychedelic effect, and antidepressant effect. Patents entitle their holders to exclude others from making, using or selling patented inventions for approximately 20 years13. The public-policy justification for patents rests on the theory that the right to exclude incentivizes drug development, an expensive endeavor, made riskier when other companies can copy an invention.

Psilocybin Rewires the Brain for People with Depression

It is important to note that the setting in which the therapy is carried out is also significant, as it facilitates the revelation of the patients’ inner landscape. The ideal environment is a quiet space, in a reclined position, wearing an eye mask, and engaging in music therapy. Few treatments are available for patients with mood disorders or post-traumatic stress disorder (PTSD) who have already failed multiple interventions. After several decades when research into psychedelics was effectively halted by federal legislation, the past several years have shown the re-emergence of thoughtful investigations studying the utility of compounds such as 3,4-methylenedioxymethamphetamine (MDMA) and psilocybin. Previously, it was thought that depression was caused by an imbalance in the brain’s level of a chemical called serotonin.

Psilocybin Shows Long-Term Benefits

However, according to the guidelines, it is only to be used “under the supervision of a health care provider in a certified doctor’s office or clinic.” Throughout history, many pre-Columbian cultures used hallucinogenic substances in magical, therapeutic, and religious rituals. However, it was not until 1938 that Swiss chemist Albert Hofmann synthesized the first synthetic hallucinogen, lysergic acid diethylamide (LSD) while working at Sandoz. Years later, Sandoz marketed LSD under the trade name Delysid as an agent for studying psychoses and as an adjunct to traditional psychotherapy. The study of cancer patients “led us to consider whether or not this treatment might be effective for people in the general depression community,” Davis says.

However, the ketamine found in his digestive tract at autopsy indicated he was also taking it orally, which is only used recreationally. Due to its psychoactive effects, drugs like MDMA are often taken at raves, clubs, or music festivals, where participants use these substances to amplify their experience. Psilocybin is the active ingredient in “magic mushrooms.” Amber is greeted warmly by the therapist who previously met her for preparatory sessions. She gets comfortable in a large chair and shortly thereafter is given a capsule of synthetic, pharmaceutical-grade psilocybin to swallow with water.

Psilocybin is derived from the fungi Psilocybe cubensis, Psilocybe mexicana, and related species. Magic mushrooms have been used for thousands of years in religious rituals by indigenous are psychedelics addictive people worldwide and as treatments for physical ailments. There are more than 300 species of psilocybin-containing mushrooms, and 13 are listed as having been used by indigenous people.

• For two decades, drug-overdose deaths have risen exponentially, and suicide rates have steadily increased.
• Scores for each section range from 0 to 10,29 and the total score was calculated as the mean score of all 3 sections.
• Similarly, it could recommend the rescheduling of psilocybin because the available evidence no longer supports its current classification.
• As stated above, it is possible that psilocybin’s antidepressant effect is mediated through rapid activation of 5-HT receptors other than those involved in the psychedelic experience.
