Many scholars assume that the ancient Nasca practiced a form of shamanism on the south coast of present-day Peru (c. 1–750 CE). Typically, the identification of entheogens and shaman figures as subject matter in the vast corpus of Nasca polychrome ceramics supports those claims; however, visual analysis of the vessel forms and images reveals further evidence of a deeper understanding of...

San Pedro, a mescaline containing cactus, has been used for thousands of years and is currently popular as a psychedelic substance in ceremonial retreats in Europe. The current research investigates the consciousness altering effects of San Pedro. Forty-two participants who joined ceremonial psychedelic retreats in the Netherlands were investigated with questionnaires probing 11 dimensions of...

Abstract The use of recreational drugs like ephedrine, norephedrine, 3,4-methylenedioxymethamphetamine (MDMA), and mescaline can lead to intoxication and, at worst, to death. One reason for a fatal course of intoxication with these drugs might lie in cardiac arrhythmias. To the best of our knowledge, their inotropic effects have not yet been studied in isolated human cardiac preparations....

The paper deals with a case report of a 41-year-old man who in search of the meaning of life in a so-called “shamanic ritual” drank tea made from the San Pedro cactus as well as paste made of the same plant. The hallucinations were post poned and started after 9.5 hours caracterised by a psychotic reaction with symptoms of catatonia. He was admitted to our Department of Psychiatry where he was...

Abstract N,N ‐Diformylmescaline, a novel analogue of mescaline, has recently been detected in Australia in two unrelated seizures. To confirm the identification, a three‐step synthesis from 3,4,5‐trimethoxyphenylacetic acid was devised. However, purification of the final product proved problematic with the compound prone to degradation in solution. Analysis of the compound by LC–MS indicated...

The pharmacological mechanisms of mescaline are similar to those of other classical psychedelics, like psilocybin and lysergic acid diethylamide (LSD). Mescaline appears to be safe to consume, with most intoxications being mild and easily treatable. Improvement in mental well-being and its ability to overcome alcoholism render mescaline potentially beneficial in clinical settings. This article...

The preservation of naturally mummified bodies in the Nazca drainage and Yauca Valley provided an opportunity to analyse for the first time which of the psychoactive plants were used on the southern Peruvian coast. Toxicological analysis allows us to better understand the ancient medicine, trade network and religiosity of the region of interest. Hair samples of 22 individuals (including four...

Following a decades long period of investigational dormancy, there is renewed interest in employing psychedelics as psychiatric treatments. The academic journals, institutions, and countries that have helped sustain clinical psychedelic research and the evolution of the literature on clinical studies of psychedelics have only recently begun to be investigated. To expand upon this work, we...

The utility of classical drugs used to treat psychiatric disorders (e.g., antidepressants, anxiolytics) is often limited by issues of lack of efficacy, delayed onset of action or side effects. Psychoactive substances have a long history of being used as tools to alter consciousness and as a gateway to approach the unknown and the divinities. These substances were initially obtained from plants...

Microdosing—the intermittent ingestion of minute, sub-hallucinogenic amounts of psychedelic substances, repeatedly and over time—has become a widespread, albeit largely understudied, phenomenon. Regulations around using psychedelics at any dose—micro, mini, macro, or mega—pose all sorts of difficulties for those who wish to systematically study the effects of Schedule I drugs, especially in the...

Medical hallucinogens have been important compounds of research interest in recent years. Computational chemistry methods like Density Functional Theory (DFT) calculations at BP86/Def2-TZVP level are carried out to get more insight into the structural preferences and mechanism of hallucinogens like psilocybin and mescaline derivatives at the molecular level. The molecular structure, reactivity,...

In this novel the presence of the San Pedro cactus shows not only the shaman’s therapeutic operations but also the way in which the ecstasy produced by its consumption is defined as a chemical and aesthetic procedure, with somatic-political repercussions and experimental aspirations from the point of view of its literary concreteness. In this way, the experimentation of the visions that is...

Abstract This is a narrative review about the role of classic and two atypical psychedelics in the treatment of unipolar and bipolar depression. Since the 1990s, psychedelics experience a renaissance in biomedical research. The so-called classic psychedelics include lysergic acid diethylamide (LSD), psilocybin, mescaline and ayahuasca. Characteristic effects like alterations in sensory...

Abstract Tobacco use is the single largest cause of preventable death worldwide, but none of the established treatments aimed at smoking cessation work for a majority of smokers. As such, there is an urgent need for interventions capable of reliably treating nicotine addiction. The use of classic psychedelics has been associated with lower odds of many forms of substance dependence. Here we...

Hallucinogenic drugs potently affect brain and behavior and have also recently emerged as potentially promising agents in pharmacotherapy. Complementing laboratory rodents, the zebrafish (Danio rerio) is a powerful animal model organism for screening neuroactive drugs, including hallucinogens. Here, we test a battery of ten novel N-benzyl-2-phenylethylamine (NBPEA) derivatives with the 2,4- and...

Psychedelics such as lysergic acid diethylamide (LSD), psilocybin (magic mushrooms), and mescaline exhibit intense effects on the human brain and behaviour. In recent years, there has been a surge in studies investigating these drugs because clinical studies have shown that these once banned drugs are well tolerated and efficacious in medically supervised low doses called microdosing....

Objective: An effective way to protect the currently endangered wild populations of Lophophora williamsii is to select mescaline-rich specimens for selective propagation. Also, users of these and other entheogenic cacti are in need of an accessible way of dosing extracts. This research aims to introduce and validate an accessible procedure for the quantification of mescaline in fresh cactus...

At first glance, it appears there is little difference between the molecular structures of methylenedioxymethamphetamine (MDMA), which has an N -methyl attached to its amino group, and methylenedioxyamphetamine (MDA), a primary amine that is recognized to have hallucinogenic activity. It is known from studies with other hallucinogenic amphetamines that N -methylation of hallucinogenic...

This chapter highlights the similarities in chemical structure and physiologic effects of hallucinogens, as well as their metabolism, therapeutic uses and potential for misuse or abuse. Special attention is given to the testing process, with an emphasis on interpretation of test results. Hallucinogens are drugs that alter an individual's perception of reality. The classic hallucinogens include...
