Psychedelics, including psilocybin, lysergic acid diethylamide, and dimethyltryptamine, and entactogens such as 3,4-methylenedioxymethamphetamine are being investigated for treatment-resistant depression, post-traumatic stress disorder, anxiety, and substance use disorders. These compounds act primarily through serotonin 5-HT2A receptor agonism (psychedelics) or monoamine release (MDMA),...
The emergence of microdosing introduced a novel approach to consuming classic psychedelic substances, such as LSD (lysergic acid diethylamide) and psilocybin mushrooms, in ways previously unconventional. Whereas traditional illicit substance use often seeks euphoric experiences, microdosing deliberately avoids such effects in favor of perceived self-enhancing benefits. Increasingly common in...
BACKGROUND: Over the past ten years, several psychedelic compounds, including tryptamines like lysergic acid diethylamide/LSD, psilocybin, ayahuasca, and dimethyltryptamine/DMT, have been tested in clinical trials for a range of psychiatric conditions, such as anxiety and depression. While these compounds are relatively available for treatment, ketamine and its S(+) enantiomer, esketamine, are...

Objectives: This study investigates psychedelic drugs to treat substance use disorder (SUD). Researchers have recently begun conducting clinical trials of psychedelic treatment for SUD. The current meta-analysis investigates the extent of efficacy in alleviating SM behaviours (P) using psychedelic therapy (I), concurrent with determining which psychedelic enables the greatest effect (C) as a...
Psychedelics including psilocybin, dimethyltryptamine, and lysergic acid diethylamide are known to disrupt the normal flow of time perception, for example, producing time dilation, compression, and loss of time. These temporal anomalies provide interesting clues about how the brain processes time, what consciousness is, and what produces the sense of self. This opinion article discusses the...
Psychedelic clinical research is expanding rapidly. This review analyses the state and trends in psychedelic clinical trial registrations. A systematic search of ClinicalTrials.Gov was conducted on 11 November 2024, to identify registered interventional trials investigating (therapeutic) effects of serotonergic psychedelics (e.g. lysergic acid diethylamide [LSD], psilocybin, [5-MeO-]DMT)....
Psychedelics are mind-altering substances that have shown promising effects in the treatment of neuropsychiatric disorders owing to their antidepressant, anxiolytic and antiaddictive effects. However, data on their developmental toxicity is scarce, which might hinder its therapeutic suitability, and preclinical data on their behavioral effects is mainly restricted to rodents. In this context,...
Psychedelic research is progressing at breakneck speed and is creating new challenges for drug developers, regulatory authorities, and legislators. Most “classic” psychedelics undergoing clinical investigation are C-I controlled drugs with perceived high potential for abuse and no medical use. These and next-generation psychedelic drug-candidates require scientific and clinical assessment of...
Psychiatric illness, particularly stress-related disorders including depression, anxiety and posttraumatic stress disorder, presents a considerable health burden worldwide with high prevalence, disabling symptoms, and scant efficacy of available treatments. Chronic stress is a major contributor to the origin and development of these conditions, to the detriment of both individual and, by...
Background: Psychedelics such as lysergic acid diethylamide (LSD) and psilocybin have shown a beneficial effect on substance use disorder (SUD) symptoms. In this systematic review, we aimed to assess the efficacy and safety of psychoactive tryptamines in patients with an SUD or non-substance-related disorder (i.e., gambling disorder) in order to provide a comprehensive overview of the available...
