New psychoactive substances (NPS) appear on the recreational market on a monthly basis, with unclear toxicology, resulting in an increasing number of fatalities. Identification of drug targets and potencies is crucial for understanding and treating intoxications and for scheduling processes. In this study 60 NPS and metabolites belonging to opioids, cannabinoids and serotonergic hallucinogens...
Abstract The microdosing of mind-altering substances, like LSD and magic mushrooms, is a trend among young creatives, who report enhanced creativity, improved focus, and other productivity-enhancing effects. This chapter, Chemical Creativity , describes how both users and researchers have been exploring the range of effects of microdosing, including through more experimental ethnographic...
Microdosing psychedelic drugs-that is, taking sub-behavioral doses of lysergic acid diethylamide (LSD) or psilocybin-is a growing practice in Western societies. Taken mainly for creative or mood-enhancing purposes, thousands of users are increasingly being exposed to (micro)doses of psychedelic drugs. In this systematic review, we searched the available evidence from human studies, focusing our...
There is a long history of psychedelic use throughout history. A great deal of research was conducted on the possible benefits of psychedelics until LSD and psilocybin became street drugs in the 1960s with reported negative effects. Declared illegal in the late 1960s, research slowed on the benefits of such drugs. A new version of the “street” use of psychedelics has emerged in the form of...
Antiretroviral drugs are the mainstay of treatment for human immunodeficiency virus (HIV) infection. Lifelong highly active antiretroviral therapy (HAART) is indicated to prevent disease progression to acquired immunodeficiency syndrome (AIDS). Efavirenz was a first-line component of HAART across the world for many years. The purpose of this article is to review the psychotropic properties of...
Abstract There are about 400,000 species of plants in this world. Only a small fraction, perhaps 100 in number, contain hallucinogenic chemicals. Nearly a century ago, Lewis Lewin, professor of pharmacology at the University of Berlin, in speaking of drugs he called phantasticants, said “The passionate desire which … leads man to flee from the monotony of daily life … has made him discover...
Psychedelic new psychoactive substances (NPS), compounds exerting their main pharmacological effects through the activation of the serotonin 2A receptor (5-HT2AR), continuously comprise a substantial portion of the reported NPS. However, these substances and their exact mechanism of action, differentiating them from non-psychedelic 5-HT2AR agonists, require further characterization. One...
BACKGROUND: While cannabis has a long history of spiritual use, its normalization in Western societies during the last decades has led to more recreational use. This study aimed to explore the characteristics of spiritual cannabis use as compared to recreational use and to the use of psychedelics such as LSD and psilocybin. METHODS: The study employed a mixed methods research design that...
Cortical neuron atrophy is a hallmark of depression and includes neurite retraction, dendritic spine loss, and decreased synaptic density. Psychoplastogens, small molecules capable of rapidly promoting cortical neuron growth, have been hypothesized to produce long-lasting positive effects on behavior by rectifying these deleterious structural and functional changes. Here we demonstrate that...
Recent investigations have shown that N-ethyl-N-cyclopropyl lysergamide (ECPLA) produces LSD-like behavioral effects in mice, which suggests that it may act as a hallucinogen in humans. Although the use of ECPLA as a recreational drug has been limited, key analytical data that can be used to detect ECPLA are required for future forensic and clinical investigations. ECPLA is an isomer of...
