Psychedelic use in Poland: prevalence, correlates and social attitudes

mycolabadmin

This study found that about 6% of Polish adults have tried psychedelic drugs like LSD or magic mushrooms, mostly young men in cities driven by curiosity. Most users took these substances at home and described mixed experiences. While negative attitudes toward psychedelics were common overall, people with meditation experience and previous psychedelic use had more positive views about their therapeutic potential.

Effect of psilocybin on marble burying in ICR mice: role of 5-HT1A receptors and implications for the treatment of obsessive-compulsive disorder

mycolabadmin

Researchers tested whether psilocybin mushrooms could help treat obsessive-compulsive disorder (OCD) using mice. They found that psilocybin reduced compulsive burying behavior in mice, similar to how approved OCD medications work. The study revealed that this anti-compulsive effect works through different brain mechanisms than previously thought, and that combining psilocybin with another drug called buspirone might block psychedelic effects while keeping therapeutic benefits.

Psychedelics: Alternative and Potential Therapeutic Options for Treating Mood and Anxiety Disorders

mycolabadmin

This comprehensive review explores how psychedelic drugs like psilocybin mushrooms, DMT, and LSD may offer new hope for treating depression, anxiety, and PTSD, especially for patients who don’t respond to conventional antidepressants. Historically used in spiritual ceremonies for thousands of years, these compounds are now being scientifically studied and show promise with fewer side effects than many traditional psychiatric medications. The authors emphasize that while results are encouraging, more research and regulatory approval are needed before these treatments become widely available in mainstream medicine.

A Novel, Non-Hallucinogenic Psychedelic for the Treatment of OCD and Tic Disorder

Researchers developed a new drug called HBL20017 based on psychedelic compounds that does not cause hallucinations. In animal tests, this drug significantly reduced obsessive behaviors and involuntary muscle twitches, suggesting it could treat conditions like obsessive-compulsive disorder and Tourette’s syndrome. A single dose showed beneficial effects that lasted up to 42 days, and the compound appeared safer than existing psychedelic treatments.

Attitudes toward psychedelics and psychedelic-assisted psychotherapy among Australian mental healthcare providers

mycolabadmin

Australian doctors and mental health professionals have positive views about using psychedelics like psilocybin and MDMA to treat depression and trauma, which were recently approved by regulators. However, many still have safety concerns and gaps in their knowledge, particularly psychiatrists. Most doctors learn about psychedelics from podcasts and websites rather than formal training. The study recommends that professional organizations provide better education to prepare healthcare workers for this new treatment approach.

Safety, tolerability, and clinical and neural effects of single-dose psilocybin in obsessive–compulsive disorder: protocol for a randomized, double-blind, placebo-controlled, non-crossover trial

mycolabadmin

This study tests whether psilocybin (the active compound in certain mushrooms) can help people with obsessive-compulsive disorder who haven’t responded to standard treatments. In a carefully controlled trial, participants receive either a single dose of psilocybin or a placebo while receiving psychological support, with their brain activity and symptoms monitored. The research aims to determine if this novel treatment is safe and whether it could work faster than existing medications for this difficult-to-treat condition.

Ketamine, Psychedelics, and Psychotherapy: Reframing, Redefining, Renaming Treatment Models

mycolabadmin

This paper addresses confusion about how ketamine and psychedelics are being used to treat mental health conditions like depression and PTSD. The authors propose new clear definitions to distinguish whether these drugs are used alone for their chemical effects, combined with established talk therapies, or used to create experiences that are then processed in therapy. Using these clearer definitions will help patients, doctors, and regulators better understand what treatments involve and make more informed decisions.

PsilOCD: A Pharmacological Challenge Study Evaluating the Effects of the 5-HT2A Agonist Psilocybin on the Neurocognitive and Clinical Correlates of Compulsivity

mycolabadmin

This study is investigating whether psilocybin (an active compound in magic mushrooms) can help people with obsessive-compulsive disorder (OCD) by improving their mental flexibility and brain plasticity. Participants will receive two doses of psilocybin—a low test dose and a slightly higher therapeutic dose—four weeks apart, while receiving professional psychological support. Researchers will measure changes in cognitive abilities and brain activity to understand how psilocybin might help reduce OCD symptoms like intrusive thoughts and repetitive behaviors.

Safety, feasibility, tolerability, and clinical effects of repeated psilocybin dosing combined with non-directive support in the treatment of obsessive-compulsive disorder: protocol for a randomized, waitlist-controlled trial with blinded ratings

mycolabadmin

This clinical trial is investigating whether psilocybin (a psychoactive compound found in certain mushrooms) combined with supportive counseling can help people with treatment-resistant obsessive-compulsive disorder. Researchers will give participants two doses of psilocybin while providing non-directive psychological support to help them process their experiences. The study aims to determine whether this approach is safe, tolerable, and effective at reducing OCD symptoms, and to understand the psychological mechanisms that might explain how it works.
