Researchers are actively testing psilocybin (the active part of “magic mushrooms”) as a possible treatment for several mental health problems. Early clinical trials—usually done under medical supervision with therapy before and after the drug session—have found quick improvements in some people with major depression, anxiety linked to serious illness, and other hard-to-treat conditions (but the studies are still small). (15135,15063,15056) Scientists propose several ways psilocybin might help, such as changing how brain networks communicate, boosting the brain’s ability to form new connections, and lowering brain inflammation. However, the exact reasons are not settled. Safety in careful clinical settings looks acceptable so far, but harms may be underreported, and unsupervised use can carry real risks. More and larger trials are needed, and many groups (for example people of color) were not well represented in early studies. (15132,15050,15135,15061,15095,15056)
This randomized, double‑blind, cross‑over trial gave 51 patients with life‑threatening cancer two sessions of psilocybin (one very low dose and one high dose) spaced five weeks apart. The high dose (22–30 mg/70 kg) produced large drops in clinician‑ and self‑rated depression and anxiety, and increased quality of life, meaning, and…
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…
Psychedelic "bad trips" can be intense and sometimes last past the session. Surveys and studies report that a minority of users have serious short- or long-term problems, while other people later say the experience was meaningful or helpful. Risk and duration vary by dose, setting, and support, and studies give…
This paper is a careful review of research about treatment-resistant depression. The authors looked through medical studies to see how doctors define this kind of depression, what makes it hard to assess, and which treatments have been tried. They describe drug strategies like adding lithium or thyroid hormone, switching antidepressant…
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…
This review looks at studies about classic psychedelics (like LSD, psilocybin, and DMT/ayahuasca) and their effects on neuroplasticity — the brain’s ability to change. Animal studies show these drugs can raise genes tied to plasticity and cause dendrite and synapse growth. Human results are mixed, especially when studies use blood…
The authors reviewed psychedelic-assisted psychotherapy studies published from 1993 to 2017 to see how many people of color took part. They found 18 studies with about 280 people. About 82% of participants were non-Hispanic White, while only small percentages were African American, Latino, Asian, indigenous, or mixed race. Because so…
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…
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.…
This review looked at many studies about classic psychedelics (like psilocybin and LSD), MDMA, ketamine, and plant medicines (like ayahuasca). The authors explain how these drugs can change the brain’s wiring, calm inflammatory processes, and shift key brain chemicals. Those actions may help explain why small clinical trials and animal…
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…
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…
