This article examines a range of hybrid, artistic ayahuasca ritual formations that I define as otherwise ayahuasca expressions to engage with the question of ritual reinvention. Given the kaleidoscopic multiplicity in the diffusion of the Amazonian psychoactive plant brew ayahuasca, this article argues that ritual forms navigate the tension between fixity and flexibility, and that ritual change...
This article examines how ayahuasca religions in Italy have reconfigured their ritual practices following the 2022 legal ban on ayahuasca, including replacing the brew with water and creating new forms of religious travel. The Amazonian psychoactive brew ayahuasca, traditionally used in Indigenous rituals and healing, is at the centre of transnational religions that have spread globally....

Abstract Ayahuasca profoundly alters conscious experience, yet robust, time-resolved EEG markers of its network-level effects remain limited. We combined machine learning with complex-network analysis to quantify how functional connectivity reorganizes across time and hemispheres in resting-state EEG from a randomized, double-blind, placebo-controlled trial including three 5-min sessions:...
Background: Psychedelics induce profound changes in perception and thinking; however, little is known about the neural mechanisms and prediction of these effects. Aims: Investigating ayahuasca-induced experiences, mind-wandering, and electroencephalogram (EEG) oscillations, beyond the prediction of subjective experiences by baseline EEG. Methods: In a randomised, double-blind,...
Ayahuasca is an Amazonian psychedelic brew that contains dimethyltryptamine (DMT) and beta carbolines. Prolonged use has shown changes in cognitive-behavioral tasks, and in humans, there is evidence of changes in cortical thickness and an increase in neuroplasticity factors that could lead to modifications in functional neural circuits. To investigate the long-term effects of Ayahuasca usage...

Alongside the important contributions of the harm reduction movement to improving public health in secular settings, communities that use psychedelics as religious sacraments (i.e., entheogens) have developed their own frameworks for supporting safety within their spiritual practices and hold their own conceptualizations of risk and harm. In order to understand better the lived realities of...
Abstract This study explores the first-time use of psychedelic macrodoses among Latin American adults, addressing a gap in the literature regarding naturalistic use outside clinical settings. A total of 4,810 participants from six Latin American countries completed an online survey assessing sociodemographic characteristics, substances used, consumption contexts, motivations, and subjective...

Ayahuasca is a psychoactive brew traditionally used in religious rituals by indigenous Amazonian populations and South American syncretic religions such as Santo Daime and União do Vegetal. Its psychoactive effects are primarily due to N,N-dimethyltryptamine (DMT), while harmine (HRE), a β-carboline alkaloid, inhibits monoamine oxidase (MAO), enabling DMT's oral bioavailability. Recent studies...
These findings provide preliminary evidence that while ayahuasca may alter how humans interact with the theme of death on conceptual and affective levels of cognitive processing, on automatic, perceptual unconscious levels of self-specific processing, death-denial processes appear to remain intact.
Ayahuasca is a traditional Amazonian brew composed of Psychotria viridis, containing N,N-dimethyltryptamine (DMT), and Banisteriopsis caapi, which includes harmala alkaloids such as harmine. Ayahuasca can produce potent psychoactive effects primarily due to DMT, whose metabolism is inhibited by harmine via monoamine oxidase-A enzymes. This inhibition increases DMT's systemic bioavailability,...
