Psychedelics are a hallucinogenic class of psychoactive drugs with the primary effect of activating non-ordinary states of consciousness. Due to the positive preliminary findings of these drugs in the treatment of psychiatric disorders, the number of registered clinical studies has risen significantly. In this paper, clinical studies registered on clinicaltr...
After decades of stagnancy, research on psychedelic substances (such as LSD, psilocybin or DMT) has experienced a renaissance over the last 10 years, with various major research programs being conducted across Europe and the United States. This research primarily investigates the potential of psychedelics in the treatment of mental health disorders, their sh...
ObjectivesPsychedelics are powerful psychoactive substances. Natural psychedelics have been used for millennia by human civilizations, in particular in Latin America, while synthetic psychedelics were discovered in the 50s, giving rise to a lot of research before they were prohibited. More recently, their therapeutic properties have been studied especially t...
Background:: Psilocybin (PB) is a psychoactive compound commonly found in magic mushroom ( Psilocybe cubensis ). PB is quickly converted by the body to psilocin (PI), which has a psychedelic effect through the activation of the 5-HT2A receptor in the brain. The objective of this study is to develop a physiologically based pharmacokinetic (PBPK) model of PB a...
IntroductionCannabidiol (CBD) is purportedly a promising therapeutic agent to provide relief for a variety of medical conditions with mild or no psychoactive effects. However, little is known about young adults who use cannabis and CBD-dominant products, and associations between CBD use and other drug use.MethodsYoung adults (aged 24-32) who currently used c...
This study was designed to identify trends in the top-cited classic psychedelic publications. The top 50 publications on classic psychedelics with the greatest total of number of citations and annual citation rate were identified and pooled. Unique articles (n = 76) were dichotomized by median year of publication (2010.5); the differential distribution of st...
Obsessive Compulsive Disorder (OCD) is a chronic neuropsychiatric condition, characterized by obsessions and compulsions, which is usually disabling for the suffering individual. The first-line treatment is not effective in all patients. There is evidence showing the effectiveness of psilocybin and psilocybin-containing mushrooms in the treatment of OCD symp...
Abstract Background: The misuse of illicit substances is associated with increased morbidity and mortality; thus, substance abuse is a global health concern. However, a lack of laboratory-based research has limited the scientific assessment of drug misuse in the Arabian Gulf region. Thus, the primary aim of this study was to assess the problem of illicit dru...
5-MeO-DMT is a psychoactive substance found in high concentrations in the bufotoxin of the Colorado River Toad (Bufo alvarius). Emerging evidence suggests that vaporized 5-MeO-DMT may occasion mystical experiences of comparable intensity to those occasioned by more widely studied psychedelics such as psilocybin, but no empirical study has tested this hypothe...
In nature, there are >200 species of fungi with hallucinogenic properties. These fungi are classified as Psilocybe, Gymnopilus, and Panaeolus which contain active principles with hallucinogenic properties such as ibotenic acid, psilocybin, psilocin, or baeocystin. In Chile, fungi seizures are mainly of mature specimens or spores. However, clandestine laborat...
This research is being done to study the psychological effects of psilocybin in cancer patients. Psilocybin is a naturally occurring substance found in some mushrooms that some cultures have used for centuries in religious practices. This research is being done to study the psychological effects of psilocybin in cancer patients. Psilocybin is a naturally occ...
Lysergic acid diethylamide (LSD) is one of the most potent psychoactive agents known, producing dramatic alterations of consciousness after submilligram (≥20 μg) oral doses. Following the accidental discovery of its potent psychoactive effects in 1943, it was supplied by Sandoz Laboratories as an experimental drug that might be useful as an adjunct for psych...
This chapter begins with a brief review of descriptions and definitions of mystical-type experiences and the historical connection between classic hallucinogens and mystical experiences. The chapter then explores the empirical literature on experiences with classic hallucinogens in which claims about mystical or religious experiences have been made. A psycho...
This chapter reviews what is known about the therapeutic uses of the serotonergic or classic hallucinogens, i.e., psychoactive drugs such as LSD and psilocybin that exert their effects primarily through agonist activity at serotonin 2A (5HT2A) receptors. Following a review of the history of human use and scientific study of these drugs, the data from clinica...
In recent years, new drugs, commonly known as new psychoactive substances (NPS), appeared on the market, which include, among others, synthetic cannabinoids, cathinones, and tryptamine analogs of psilocin. The aim of this work was to develop and validate a new method for simultaneous screening and quantification of 31 NPS in oral fluid by ultra-high-performa...
Background Recently, scientific interest in the therapeutic potential of serotonergic and psilocybin hallucinogens (psychedelics) such as lysergic acid diethylamide (LSD) and entactogens like 3,4-methylendioxymethamphetamine (MDMA) within the framework of psychotherapy has resumed. The present article provides an overview on the current evidence on substance...
In a large-scale ( N = 1487) general population online study, we investigated the relationship between past experience with classic psychedelic substances (e.g. LSD, psilocybin, mescaline), nature relatedness, and ecological behavior (e.g. saving water, recycling). Using structural equation modeling we found that experience with classic psychedelics uniquely...
New psychoactive substances (NPS) are a new breed of synthetically produced substances designed to mimic the effects of traditional illegal drugs. Synthetic cannabinoids and synthetic cathinones are the two most common groups, which try to mimic the effects of the natural compounds 9Δ-tetrahydrocannabinol and cathinone, respectively. Similarly, synthetic try...
There has been growing clinical, public, and media awareness and concern about the availability and potential harmfulness of so-called 'legal highs', which are more appropriately called new or novel psychoactive substances (NPS). A cat-and-mouse process has emerged wherein unknown chemists and laboratories are producing new, and as yet nonproscribed, compoun...
UnlabelledThe definition New psychoactive substances (NPS) refers to emerging drugs whose chemical structures are similar to other psychoactive compounds but not identical, representing a "legal" alternative to internationally controlled drugs. There are many categories of NPS, such as synthetic cannabinoids, synthetic cathinones, phenylethylamines, piperazi...
