Rationale:
The psychedelic brew ayahuasca is increasingly being investigated for its therapeutic potential. Animal models are essential to investigate the pharmacological effects of ayahuasca since they can control factors influencing it, such as the set and setting.
Objective:
To review and summarise data available on ayahuasca research using a...

There is an increasing availability and medical applications of cannabinoids, and growing interest in their therapeutic potential for addictive disorders.
Objectives
The objective...
Background: Preliminary evidence suggests that long-term ayahuasca use is associated with better psychosocial outcomes and less drug use; however, available data on the association between ayahuasca intake frequency and psychosocial outcomes is limited. Objectives: We sought to characterize and investigate the association of regular ayahuasca use,...
Data on cannabis use patterns and health outcome indicators for Brazil are limited. We undertook a cross-sectional internet-based survey assessing socio-demographics, cannabis use frequency, other drug use, quality-of-life (QOL), affective states (i.e. anxiety and depression), and cannabis use disorder among adult respondents in Brazil. A multinomi...
Psychedelics acutely impair cognitive functions, but these impairments decline with growing experiences with psychedelics and microdoses may even exert opposing effects. Given the recent evidence that psychedelics induce neuroplasticity, this explorative study aimed at investigating the potential of psychedelics to sub-acutely change cognition. For...
Background:
Controversy surrounds psychedelics and their potential to boost creativity. To date, psychedelic studies lack a uniform conceptualization of creativity and methodologically rigorous designs.
Aims:
This study aimed at addressing previous issues by examining the effects of lysergic acid diethylamide (LSD) on creativity using multimodal...
