Serotonergic hallucinogens, such as (+)-lysergic acid diethylamide, psilocybin, and mescaline, are somewhat enigmatic substances. Although these drugs are derived from multiple chemical families, they all produce remarkably similar effects in animals and humans, and they show cross-tolerance. This article reviews the evidence demonstrating the serotonin 5-HT2A receptor is the primary site of...
Psychoactive plants which contain hallucinogenic molecules that induce a form of altered states of consciousness (H-ASC) have been widely used during the religious rituals of many cultures throughout the centuries, while the consumption of these plants for spiritual and religious purposes is as old as human history. Some of those cultures were shaman and pagan subcultures; African native...
The hallucinogens are a class of psychoactive drugs, either synthetic or plant products, that produce auditory and/or visual hallucinations as well as thought, mood, and perceptual changes. Depending on dosage, expectation (set), and environment (setting), they also can induce euphoria and a state similar to a transcendental experience. These hallucinations can be present as part of a delirium...
This essay frames an invitation to pastoral counselors and pastoral theologians to examine connections and perhaps interactions between themselves and traditional shamanic healers who use ayahuasca in their healing ceremonies. Indigenous people in South America have used ayahuasca for centuries, and the ritual has become common among the mestizo populations in urban areas of the Amazon,...
During the colonial period, the indigenous saraguros maintained their traditions, knowledge, and practices to restore and preserve the health of their members. Unfortunately, many of their practices and medicinal resources have not been documented. In this study, we sought to document the traditional healers' (yachakkuna saraguros) knowledge about medicinal and psychoactive plants used in the...
Alcohol and drug abuse is frequent among performers and pop musicians. Many of them hope that alcohol and drugs will enhance their creativity. Scientific studies are scarce and conclusions limited for methodological reasons. Furthermore, extraordinary creativity can hardly be grasped by empirical-statistical methods. Thus, ideographic studies are necessary to learn from extraordinarily creative...
Can drugs be used intelligently and responsibly to expand human consciousness and heighten spirituality? This two-volume work presents objective scientific information and personal stories aiming to answer the question. The first of its kind, this intriguing two-volume set objectively reports on and assesses this modern psycho-social movement in world culture: the constructive medical use of...
The use of new psychoactive substances (NPS) as adulterants has received little attention in the literature. In this paper, results from Energy Control's drug checking service documenting the use of NPS as adulterants of controlled drugs are presented, and some reflections about possible explanations for this new phenomenon, potential risks for users, and challenges that it poses are discussed....
The 5-HT₂A receptor mediates the effects of serotonergic hallucinogens and may play a role in the pathophysiology of certain psychiatric disorders, including schizophrenia. Given these findings, there is a need for animal models to assess the behavioral effects of 5-HT₂A receptor activation. Our previous studies demonstrated that the phenylalkylamine hallucinogen and 5-HT₂A/₂C agonist...
