Scientific interest in psychedelics, documented since the nineteenth century, has recently resurged after decades of prohibition. Contemporary research highlights their therapeutic potential in treatment-resistant psychiatric disorders, alongside their heuristic value for studying brain networks and consciousness. This chapter reviews the historical trajectory, traditional uses, mechanisms of...
Abstract Classic serotonergic psychedelics are potent modulators of conscious awareness, yet the principles governing their effects on the temporal dynamics of brain activity remain unclear. Dominant theories propose that psychedelics increase the signal diversity and metastability of neural states, but whether this reflects a simple randomization of activity or a more structured reorganization...
The recent mainstreaming of psychedelics has distanced itself from the countercultural image of the past, yet the question of whether psychedelics are political remains pressing. What happens when psychedelics meet politics?On one hand lies the politics of the unitive mystical experience: harmony, beyond good & evil, beyond space & time, and with love to all. Studying ayahuasca groups of...
Abstract: Background: Psychedelic-assisted therapy is increasingly being explored as potential treatment for substance use disorders (SUDs). While multiple systematic reviews and meta-analyses have examined this topic, the efficacy, methodological quality, and overlap of the existing evidence base remain unclear. Methods: We conducted an umbrella review of systematic reviews and meta-analyses...
BACKGROUND: The use of psychedelics is currently increasing in the United States. Awareness of clinical trials investigating the therapeutic applications of psychedelics may result in a record number of people who use psychedelics for the first-time. This study aimed to develop a harm-reduction resource to facilitate safe and successful psychedelic experiences outside of regulated clinical and...
Acute subjective experiences induced by psychedelics have been identified as important mediators of therapeutic outcomes in many studies. Mystical experiences specifically, have been correlated with a range of therapeutic outcomes including reductions in symptoms of depression, anxiety and addiction. This paper assesses acute subjective experiences induced by an encapsulated DMT-harmala...
Amid an evolving psychedelic drug policy landscape and limitations of existing substance use disorder (SUD) treatments, a novel addiction recovery paradigm has emerged involving augmentation of 12-Step program engagement with therapeutic psychedelic use. A preliminary qualitative analysis was initiated to describe this movement by examining real-world experiences of participants in remission...
Serotonergic psychedelics and 3,4-methylendioxtmethamphetamine (MDMA) are promising treatments for mental disorders with a continuously evolving evidence base. We searched Pubmed/Scopus/clinical trial registries up to 08july2025 for double-blind randomized controlled trials (RCTs) testing MDMA or serotonergic psychedelics in patients with mental disorders. Primary outcomes were change 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...
Latour constructs a plurality of ontologies by distinguishing various modes of existence with their own type of existent. One of these modes of existence is religion, which involves invisible “beings of religion.” Latour criticizes both psychological and (onto)theological interpretations of such beings. He distinguishes between psychogenic beings that constitute the self, and beings of religion...
