The science of psychedelics is an intriguing, multi-disciplinary field that has recently been the subject of heightened public interest. This has mainly resulted from publicity associated with a number of high-profile investigations into psychedelic-assisted therapy for a range of difficult-to-treat mental health conditions. With many psychedelic substances known, including natural,...
El san Pedro (Trichocereus spp.), un cactus rico en mezcalina, y la Anadenanthera colubrina (vilca en kichwa), son plantas enteógenas (cosas que nos llevan a lo divino) prominentes en el arte andino. Este artículo explora la flor que corona este cactus (de diez pulgadas de ancho) y las numerosas variantes de este motivo exhibidas en 64 textiles wari. Las representaciones artísticas de la flor...
Natural compounds in plants are often unevenly distributed, and determining the best sampling locations to obtain the most representative results is technically challenging. Matrix-assisted laser desorption/ionization mass spectrometry imaging (MALDI-MSI) can provide the basis for formulating sampling guideline. For a succulent plant sample, ensuring the authenticity and in situ nature of the...
Abstract Classic psychedelics, lysergic acid diethylamide, psilocybin, mescaline and N,N-dimethyltryptamine, are potent psychoactive substances that have been studied for their physiological and psychological effects. However, our understanding of the potential interactions and outcomes of using these substances are used in combination with other psychoactive drugs is limited. This systematic...
2,5‐dimethoxy‐4‐bromophenethylamine (2C‐B) is a hallucinogenic phenethylamine derived from mescaline. Observational and preclinical data have suggested it to be capable of producing both subjective and emotional effects on par with other classical psychedelics and entactogens. Whereas it is the most prevalently used novel serotonergic hallucinogen to date, it's acute effects and distinctions...
Introduction Substance use disorders(SUDs) are a major health concern and current treatment interventions have proven only limited success. Despite increasing effectiveness, still about 50–60% relapse within 6–12 months after treatment [Cornelius et al ., Addict Behav. 2003;28 381-386]. SUDs are defined as chronic disorders of brain reward system, motivation, and memory processes that have gone...
Methylone is one of the most common synthetic cathinones popularized as a substitute for 3,4-methylenedioxymethamphetamine (MDMA, midomafetamine) owing to its similar effects among users. Both psychostimulants exhibit similar chemistry (i.e., methylone is a β-keto analog of MDMA) and mechanisms of action. Currently, the pharmacology of methylone remains scarcely explored in humans. Herein, we...
Bills that would decriminalize the use of psychedelics are popping up faster than magic mushrooms, but the field of psychedelics research has yet to yield supporting evidence about their safety and efficacy. Legislative reform regarding psychedelics is gaining ground, a study in JAMA Psychiatry has found. From January 1, 2019, to September 28, 2022, 25 states considered 74 bills that proposed...
Psychedelics alter consciousness and may have potential for drug development. As psychedelics are likely therapeutically active, it is important to study their effects and mechanisms using preclinical models. Here, we examined the effects of phenylalkylamine and indoleamine psychedelics on locomotor activity and exploratory behaviour using the mouse Behavioural Pattern Monitor (BPM). DOM,...
Introduction Differentiating whether plant products are natural or artificial is of great importance in many practical fields, including forensic science, food safety, cosmetics, and fast-moving consumer goods. Information about the topographic distribution of compounds is an important criterion for answering this question. However, of equal importance is the likelihood that topographic spatial...
The need to identify effective therapies for the treatment of psychiatric disorders is a particularly important issue in modern societies. In addition, difficulties in finding new drugs have led pharmacologists to review and re-evaluate some past molecules, including psychedelics. For several years there has been growing interest among psychotherapists in psilocybin or lysergic acid...
Objective Classic psychedelics (LSD, psilocybin, and peyote/mescaline) have been used to support addiction treatment in a variety of contexts ranging from ceremonial use to clinical trials. The aim of this study was to test the hypothesis that past naturalistic use of classic psychedelics would be associated with decreased prevalence of substance use disorder, when controlling for known...
Alzheimer's disease (AD) is related to the presence of extracellular aggregated amyloid-β peptide (Aβ), which binds copper(II) with high affinity in its N-terminal region. In this sense, two new 1-methylimidazole-containing N-acylhydrazonic metallophores, namely, X1TMP and X1Benz, were synthesized as hydrochlorides and characterized. The compound X1TMP contains the 3,4,5-trimethoxybenzoyl...
Classic psychedelics have been shown to exert therapeutic potential for the treatment of various psychiatric disorders, neuropsychiatric diseases, and neuronal damage. Besides their psychopharmacological activity, psychedelics have been reported to modulate immune functions. There has thus far been a sparse exploration of the direct immune-modulating effect of psychedelics on human immune cells...
Since the dawn of civilization, ancient cultures have utilized hallucinogens from plants and fungi in the context of religious and healing practices. Recently, their use has expanded to other cultures. Hallucinogens are natural or synthetic substances that alter the perception of reality at nontoxic doses, producing intense psychological and physiological effects. The initial research on...
