This article describes the Swiss limited access program for psychedelic/3,4-methylenedioxymethamphetamine (MDMA)-assisted therapy. The Swiss Federal Office of Public Health can issue authorizations for the limited medical use of otherwise prohibited substances. To be eligible, patients suffer from a mostly incurable disease, the prohibited substance can alleviate the suffering, and there are no...
Approximately 6% of Polish adults, mostly young men living in urban areas, reported using classic psychedelics, particularly LSD and psilocybin mushrooms. Further research and educational efforts are needed to support the scientific exploration of PAT, and to help shift public perceptions of its therapeutic potential.
There is a growing body of clinical research on the therapeutic potential of psychedelics for the treatment of mental health disorders, notably depression. Accordingly, the new revision of the European Medicines Agency guideline on the clinical investigation of products for depression will incorporate a section covering specific regulatory recommendations for the design of studies with...
This chapter reviews the effects of classic psychedelics on human oscillatory brain activity, as measured by resting-state electroencephalography (EEG) and magnetoencephalography (MEG). Across moderate to high doses of LSD, psilocybin, ayahuasca, and DMT, a consistent reduction in alpha power (8-13 Hz) emerges, particularly in occipital regions. Below 30 Hz, desynchronization is typical,...
Clinical trials using full doses of psychedelics have provided preliminary evidence supporting their safety and efficacy in treating a variety of physical and psychological conditions. Anecdotal reports indicate that even very small amounts of these substances may provide therapeutic benefits, though robust clinical studies are still needed. This chapter reviews the current experimental studies...
To design therapeutic trials and select the most appropriate substance and dose for an indication, a detailed understanding of clinical pharmacology is crucial. In recent years, several studies have explored the human pharmacology of different psychedelics and 3,4-methylendioxymethylamphetamin (MDMA). This chapter summarizes pharmacological characteristics of the serotonergic psychedelics...
Silene undulata is historically used for inducing vivid and prophetic lucid dreams, but limited information exists on its phytochemical composition and potential pharmacological properties. This study aimed to investigate the phytochemical composition of S. undulata through LC-MS/MS analysis and explore its potential serotonergic activity, which could support and confirm the traditional use of...
Drugs sold on cryptomarkets are thought to have lower levels of adulteration and higher strength compared with those sourced off-line. The present study aimed to determine whether cryptomarket and off-line-sourced 3,4-methylenedioxy-N-methamphetamine (MDMA), cocaine, amphetamine, methamphetamine and lysergic acid diethylamide (LSD) differed in adulteration and strength. A between-groups design...
Although studies of psychedelic-assisted psychotherapy are accumulating, there is no consensus regarding best practice of the psychotherapeutic component. In this systematic review, we summarised the quality of reporting on psychological interventions in research about psychedelic treatments. The design followed PRISMA guidelines and was preregistered in PROSPERO (CRD42022319221). We searched...
1. In the published article, there was an error. The error was regarding the average number of ayahuasca uses in the ayahuasca group in Study 1. A correction has been made to the Results section in lines 387-390. This sentence previously stated:Briefly, on average, our study participants have used ayahuasca (mean = 69.4 ± 98.7), 6.4 times more than psilocybin (mean = 10.7 ± 15.4, U = 1378, p <...
