Single-Dose Psilocybin for a Treatment-Resistant Episode of Major Depression

Guy M. Goodwin, Scott T. Aaronson, Oscar Alvarez, Peter C. Arden, Annie Baker, James Bennett, et al.
New England Journal of Medicine Summary & key facts 2022 980 citations

Compass Pathways reported early results from its first Phase 3 trial of synthetic psilocybin (COMP360) for treatment‑resistant depression. In 258 patients, the 25 mg dose showed a statistically significant improvement versus placebo on the MADRS depression scale at week 6 (a 3.6‑point difference, p < 0.001). The Data and Safety…

Psychedelics reopen the social reward learning critical period

Romain Nardou, Edward J. Sawyer, Young Jun Song, M. F. Wilkinson, Yasmin Padovan‐Hernandez, Júnia L. de Deus, et al.
Nature Summary & key facts 2023 303 citations

Researchers gave different psychedelic drugs to mice and found the drugs could reopen a window of brain plasticity used for learning social rewards. This reopened window went along with changes in a social hormone system in a key reward area of the brain and with changes in genes that control…

A systematic study of microdosing psychedelics

Vince Polito, Richard J. Stevenson
PLoS ONE Summary & key facts 2019 234 citations

This observational study followed 98 people who microdosed psychedelics over six weeks and found that people reported better psychological functioning on days they took a microdose, but there was little evidence that those effects lasted into the next days. Among 63 people who completed formal tests before and after the…

Psychedelic-Assisted Psychotherapy: A Paradigm Shift in Psychiatric Research and Development

Eduardo Ekman Schenberg
Frontiers in Pharmacology Summary & key facts 2018 229 citations

This paper describes psychedelic-assisted psychotherapy, which means giving drugs like ketamine, MDMA, psilocybin, LSD or ibogaine together with guided therapy. The authors say this approach has shown promising safety and benefits so far, even for people who did not get better with usual treatments. They also argue that these therapies…

Metabolism of psilocybin and psilocin: clinical and forensic toxicological relevance

Ricardo Jorge Dinis‐Oliveira
Drug Metabolism Reviews Summary & key facts 2017 217 citations

This review explains how the mushroom drugs psilocybin and psilocin are broken down in the body. Psilocybin is mainly a pro-drug that enzymes convert into the active compound psilocin. Psilocin is then further changed, and the main substance found in urine is psilocin-O-glucuronide, which matters for clinical and forensic testing.…

Microdosing psychedelics: More questions than answers? An overview and suggestions for future research

Kim P. C. Kuypers, Livia Ng, David Erritzøe, Gitte M. Knudsen, Charles D. Nichols, David E. Nichols, et al.
Journal of Psychopharmacology Summary & key facts 2019 213 citations

Microdosing means taking a very small, sub‑hallucinogenic amount of a psychedelic drug. Research so far is limited and mixed: some large observational studies report small-to-medium mood gains, but at least one randomized trial found no objective benefit. There is no standard definition of microdosing, potency and legality vary, and long‑term…

The psychedelic renaissance and the limitations of a White-dominant medical framework: A call for indigenous and ethnic minority inclusion

Jamilah R. George, Timothy I. Michaels, Jae Sevelius, Monnica T. Williams
Journal of Psychedelic Studies Summary & key facts 2019 212 citations

This paper reviews the recent comeback of psychedelic research and points out that much of that work borrows from indigenous healing traditions. The authors say Indigenous people, ethnic and racial minorities, women, and other marginalized groups are often left out of research and the mainstream story about psychedelic medicine. The…

Psychedelic Treatments for Psychiatric Disorders: A Systematic Review and Thematic Synthesis of Patient Experiences in Qualitative Studies

Joost J. Breeksema, Alistair Niemeijer, Erwin Krediet, Eric Vermetten, Robert A. Schoevers
CNS Drugs Summary & key facts 2020 207 citations

Researchers collected and read 15 studies where patients described their own experiences with psychedelic treatments for mental disorders. These studies looked at about 180 patient accounts across different drugs and different illnesses. Even though the drugs and treatment settings were very different, many patients described similar helpful processes, such as…

Default Mode Network Modulation by Psychedelics: A Systematic Review

James J Gattuso, Daniel Perkins, Simon Ruffell, Andrew J. Lawrence, Daniël Hoyer, Laura H. Jacobson, et al.

This systematic review looked at how classic psychedelics (LSD, psilocybin, ayahuasca) change activity in the brain’s Default Mode Network (DMN). The studies commonly found an acute disruption of connectivity inside the DMN and more communication between other resting‑state brain networks during the drug experience. The authors note these DMN changes…

Psychedelics alter metaphysical beliefs

Christopher Timmermann, Hannes Kettner, Chris Letheby, Leor Roseman, Fernando E. Rosas, Robin Carhart‐Harris
Scientific Reports Summary & key facts 2021 195 citations

Researchers used a large prospective online survey to test whether psychedelic drug use changes people’s metaphysical beliefs. After psychedelic use, people tended to move away from physicalist or materialist views and toward panpsychism and fatalism. Except for fatalism, these shifts lasted for at least 6 months. The shifts were linked…

Psychedelic Communitas: Intersubjective Experience During Psychedelic Group Sessions Predicts Enduring Changes in Psychological Wellbeing and Social Connectedness

Hannes Kettner, Fernando E. Rosas, Christopher Timmermann, Laura Kärtner, Robin Carhart‐Harris, Leor Roseman
Frontiers in Pharmacology Summary & key facts 2021 192 citations

Researchers surveyed 886 people who attended guided psychedelic retreats to test a scale of shared, togetherness experiences called "communitas." They found that stronger communitas during ceremonies was linked to small but measurable increases in psychological wellbeing and social connectedness up to four weeks after the retreat. Good relationships with facilitators,…

Psychedelic medicine: a re-emerging therapeutic paradigm

Kenneth W. Tupper, Evan Wood, Richard Yensen, Matthew W. Johnson

Researchers around the world have started clinical studies again to see if psychedelic drugs can help treat serious mental health problems. This work picks up after research that stopped around the 1950s. Scientists are running controlled studies to test whether these substances can safely reduce problems like depression, anxiety, addiction…
