The use of psilocybin to treat alcohol use disorder is very promising, but its mechanisms of action remain poorly understood. We combined behavioural, pharmacological and gene expression analyses to decipher the mechanisms of action of psilocybin, for the first time, when injected into the brain. Male Long Evans rats underwent chronic operant ethanol self-ad...
In vivo, psilocybin is rapidly dephosphorylated to psilocin which induces psychedelic effects by interacting with the 5-HT2A receptor. Psilocin primarily undergoes glucuronidation or conversion to 4-hydroxyindole-3-acetic acid (4-HIAA). Herein, we investigated psilocybin’s metabolic pathways in vitro and in vivo, conducting a thorough analysis of the enzymes...
BACKGROUND: Psilocybin offers new hope for treating mood disorders due to its rapid and sustained antidepressant effects, as standard medications require weeks or months to exert their effects. However, the mechanisms underlying this action of psilocybin have not been identified. AIMS: To investigate whether psilocybin has rapid and sustained antidepressant-...
High Resolution Image Download MS PowerPoint Slide Classical psychedelics such as psilocybin, lysergic acid diethylamide (LSD), and N,N -dimethyltryptamine (DMT) are showing promising results in clinical trials for a range of psychiatric indications, including depression, anxiety, and substance abuse disorder. These compounds are characterized by broad pharm...
Background: Immediate early genes (IEGs) are rapidly activated and initiate diverse cellular processes including neuroplasticity. We report the effect of psilocybin (PSIL), PSIL-containing psychedelic mushroom extract (PME) and 5-hydroxytryptophan (5-HTP) on expression of the IEGs, cfos, egr1, and egr2 in mouse somatosensory cortex (SSC). Methods: In our ini...
BACKGROUND: Reference to an intrinsic healing mechanism or an 'inner healer' is commonplace amongst psychedelic drug-using cultures. The 'inner healer' refers to the belief that psychedelic compounds, plants or concoctions have an intrinsically regenerative action on the mind and brain, analogous to intrinsic healing mechanisms within the physical body, for ...
Psilocybin, and its metabolite psilocin, induces psychedelic effects through activation of the 5-HT2A receptor. Psilocybin has been proposed as a treatment for depression and anxiety but sometimes induces anxiety in humans. An understanding of mechanisms underlying the anxiety response will help to better develop therapeutic prospects of psychedelics. In the...

BACKGROUND: There is growing evidence for the therapeutic effects of the psychedelic drug psilocybin for major depression. However, due to the lack of safety data on combining psilocybin with selective serotonin reuptake inhibitors (SSRIs) and serotonin-norepinephrine reuptake inhibitors (SNRIs) and concerns that there may be a negative interaction on effica...
Purpose: research of such items of illicit drug trafficking as plants and plant parts containing psychoactive substances. Methodology: study and analysis of judicial practice of higher courts and scientific research of natural science specialists; formal legal and technical legal methods. Conclusions: there is a lack of due attention to the problem of sellin...
With use of psychedelic drugs in the general population on the increase, there has been concern over their potential association with the experience of hallucinations or flashback-like phenomena after the drugs' pharmacological effects have subsided. Investigators conducted a longitudinal study to examine the relationship between psychedelic use and unusual ...
A single 25-mg dose of psilocybin resulted in improvement in depressive symptoms in all 15 participants in an open-label nonrandomized trial enrolling adults with bipolar II disorder. Twelve of the 15 participants met response and remission criteria at the study's 12-week endpoint.
Psilocybin, a naturally occurring, tryptamine alkaloid prodrug, is currently being investigated for the treatment of a range of psychiatric disorders. Preclinical reports suggest that the biological effects of psilocybin-containing mushroom extract or "full spectrum" (psychedelic) mushroom extract (PME), may differ from those of chemically synthesized psiloc...
Despite common depictions in the media, there is little scientific evidence on microdosing psychedelic drugs. We assessed awareness, prevalence, and dosing practices of microdosing psychedelic drugs among young adults 18-22 years old from Southern California (2018-2019). We examined whether sociodemographic factors, personality traits, mental health, or othe...
