Driving under the influence of drugs (DUID) is a worldwide problem. Several countries have adopted DUID legislations which prove their deterrent effect and impact on road safety. However, the use of new psychoactive substances (NPS) and prescription drugs is not known, as the applied roadside screening tests have not yet been adapted for these compounds. In this study, 558 blood samples...
New psychoactive substances (NPS) are on offer worldwide online, in order to shed light on the purity and price of these substances in the European Union, a research collaboration was set up involving France, United Kingdom (UK), the Netherlands, Czech Republic and Poland. Per country, around 10 different NPS were test purchased from different webshops. Then, chemical analysis of NPS was done...
Background: Ayahuasca is a plant tea containing the psychedelic 5-HT2A agonist N,N-dimethyltryptamine and harmala monoamine-oxidase inhibitors. Acute administration leads to neurophysiological modifications in brain regions of the default mode network, purportedly through a glutamatergic mechanism. Post-acutely, ayahuasca potentiates mindfulness capacities in volunteers and induces rapid and...
Ayahuasca is a psychoactive beverage used ancestrally by indigenous Amazonian tribes and, more recently, by Christian religions in Brazil and other countries. This study aimed to investigate the reproductive effects of this beverage in male Wistar rats after chronic exposure. The rats were treated by gavage every other day for 70 days at 0 (control), 1, 2, 4 and 8 the dose used in a religious...
With clinical psychiatrist Rick Strassman's DMT: The Spirit Molecule as a vehicle, the pineal gland has become a popularly enigmatic organ that quite literally excretes mystery. Strassman’s top selling book documented ground-breaking clinical trials with the powerful mind altering compound DMT (N,N-dimethyltryptamine) conducted at the University of New Mexico in the early 1990s. Inflected with...
The phytochemical study of hexane, chloroform and methanol extracts from leaves of Psychotria viridis resulted in the identification of: the pentacyclic triterpenes, ursolic and oleanolic acid; the steroids, 24-methylene-cycloartanol, stigmasterol and β-sitosterol; the glycosylated steroids 3-O-β-D-glucosyl-β-sitosterol and 3-O-β-D-glucosyl-stigmasterol; a polyunsaturated triterpene, squalene;...
Psychotria viridis is one of the species that produces N,N-dimethyltryptamine. Its decoction \ntogether with other species, such as Banisteriopsis caapi, produces ayahuasca, a beverage used for \nritualistic and medicinal purposes. The goal of this study was to understand how environmental \nfactors and cultivation methods influenced the content of N,N-dimethyltryptamine in P. viridis. \nOver...
Many N,N-dialkylated tryptamines show psychoactive properties in humans and the number of derivatives involved in multidisciplinary areas of research has grown over the last few decades. Whereas some derivatives form the basis of a range of medicinal products, others are predominantly encountered as recreational drugs, and in some cases, the areas of therapeutic and recreational use can...

Arrow poisons are made of alkaloids extracted mainly from the Menispermaceae ( Chondrodendron spp.), as well as the Loganiaceae ( Strychnos...
