Ayahuasca is a psychoactive beverage used for magico-religious purposes in the Amazon. Recently, Brazilian syncretic churches have helped spread the ritual use of ayahuasca abroad. This trend has raised concerns that regular use of this N,N-dimethyltryptamine-containing tea may lead to the medical and psychosocial problems typically associated with drugs of abuse. Here we assess potential drug...
Serotonin and the hallucinogenic metabolites of tryptamines, dimethylated tryptamines, activate the serotonin 2A receptor (5‐HT2AR), which is implicated in numerous mental health disorders. We have previously demonstrated that the 5‐HT2AR is differentially regulated by βarrestin2 (βarr2) depending upon the agonist; here we utilized βarr2 knockout mice to compare signaling profiles in vivo, by...
The ethnobotanical literature of Amazonian South America has been surveyed, compiled and organized. This information allowed the identification of certain taxonomic groups and plants with specific uses which seem promising for further research. The use of Justicia pectoralis as an additive to hallucinogenic Virola based snuffs has been investigated. No alkaloidal compounds could be detected in...
Ethnobotanical, phytochemical, and pharmacological investigations of two Amazonian hallucinogens are presented. The extant literature on the botany, chemistry, and ethnopharmacology of the Malpighiaceous and Myristicaceous hallucinogens is reviewed. The hallucinogenic beverage ayahuasca is prepared from the woody liana Banisteriopsis caapi (Malpighiaceae) and various admixture plants which...

A ayahuasca é utilizada como sacramento de religiões como o Santo Daime, a Barquinha, a União do Vegetal e as suas dissidências. Nesses contextos, é geralmente preparada utilizando talos de Banisteriopsis caapi e folhas de Psychotria viridis, sendo seus principais alcalóides as beta-carbolinas harmina, tetrahidroharmina (THH) e harmalina e a triptamina dimetiltriptamina (DMT) (Callaway, 2005;...
Problems associated with the increasing abuse of plant-derived psychoactive substances have recently attracted attention. This study involved bioanalytical and clinical examinations of intoxication cases suspected to be linked to such plant materials. Urine samples were collected at emergency wards in Sweden from patients who either admitted or were suspected of ingestion of psychoactive plant...
Direct Analysis in Real Time (DART) is a novel ionization technique that provides for the rapid ionization of small molecules under ambient conditions. To investigate the trend of non-controlled psychotropic plants of abuse in Japan, a rapid screening method, without sample preparation, was developed using DART-time of flight mass spectrometer (TOFMS) for plant products. The major psychotropic...

The purpose of the study was to research trance and altered states of consciousness (ASC), within dance, psychotherapy and anthropological literature, so that dance/movement therapists may practice with an informed understanding of the altered state experience, its potential therapeutic benefit, and methods for working with altered states in the practice of dance/movement therapy (DMT). The...
Pursuant to the Controlled Substances Act (CSA), DEA collects and reviews scientific, medical and other data for substances with abuse potential for possible placement under the CSA. The administrative process for scheduling is ongoing for indiplon, carisoprodol, dextromethorphan, salvinorin A and several petitions requesting a change in the control status of nabilone, methylphenidate product,...
