Serotonergic hallucinogens and cannabinoids may alter the recognition of emotions in facial expressions (REFE). Cannabidiol (CBD) attenuates the psychoactive effects of the cannabinoid-1 agonist tetrahydrocannabinol. Ayahuasca is a dimethyltryptamine-containing hallucinogenic decoction. It is unknown if CBD may moderate and attenuate the effects of ayahuasca on REFE. Seventeen healthy...

N,N-dimethyltryptamine (DMT) is a naturally occurring serotonergic psychedelic found in natural plants around the globe. As the main psychoactive component in ayahuasca, which also contains monoamine oxidase inhibitors, DMT has been consumed as plant-based brew by indigenous peoples for centuries. Further research is required to delineate the therapeutic utility of DMT. Although previous...

Ayahuasca is a South American plant hallucinogen rich in the psychedelic N,N-dimethyltryptamine and β-carbolines (mainly harmine). Preclinical and observational studies suggest that ayahuasca exerts beneficial effects in substance use disorders, but these potentials were never assessed in a clinical trial. Single-center, single-blind, feasibility, proof-of-concept study, assessing the effects...

Ayahuasca ceremonies organize care through preparation, accompaniment, observation, and responses to distress. These functions resemble nursing work, but their purposes, authority, and accountability differ. This article examines what nursing can learn from documented ceremonial arrangements and what changes when a licensed nurse participates. It brings ethnographic accounts, religious...

Ayahuasca, used religiously for centuries by Amazonian Indigenous peoples and increasingly studied for its therapeutic potential, owes its psychoactivity to two plants: Psychotria viridis supplies N,N-dimethyltryptamine (DMT), whereas Banisteriopsis caapi supplies beta-carbolines that render DMT orally active. Here we show that the two plants have distinct genome histories: P. viridis is...

Abstract Ayahuasca, an amazonian brew containing the serotonergic psychedelic substance N,N-dimethyltryptamine (DMT), induces distinctive visual perceptual phenomenology, yet the neural mechanisms underlying the interplay between external visual drive and internal imagery remain unknown. Using a placebo-controlled, within-subject fMRI design, the present study investigated the impact of...

Research on coercive control in high-demand religious groups, on religiosity and substance use, and on ritual ayahuasca practice is often discussed as though it described a single phenomenon: intense religious group life and its relationship to psychoactive substances. This critical narrative review argues that the three bodies of work describe analytically distinct processes, rest on evidence...

This article describes a case of a 'spiritual attack' in the context of Amazonian ayahuasca ceremonies. These attacks are often assumed to be imaginary, and there is relatively little information available about them. Specifically, there appears to be no documentation about possible mechanisms of action for these attacks. Subjectively, they typically appear as context-dependent visions or...

Background: N,N-dimethyltryptamine (DMT) is a naturally-occurring serotonergic psychedelic found in natural plants around the globe. As the main psychoactive component in ayahuasca, which also contains monoamine oxidase (MAO) inhibitors, DMT has been consumed as plant-based brew by indigenous peoples for centuries. Further research is required to delineate the therapeutic utility of DMT.Areas...

This systematic review evaluates the relationship between classical psychedelic drugs (D-Lysergic acid N,N-diethylamide, psilocybin, ayahuasca/N-N-dimethyl-tryptamine, and mescaline) and the emergence of psychotic symptoms, aiming to synthesize evidence from contemporary studies (1984-2025) regarding the risk factors, prevalence, and clinical characteristics of psychosis related to psychedelic...
