: Ketamine's history begins in the 1950s in Detroit, Michigan, at Parke-Davis Laboratories. On 26 March 1956, Harold V. Maddox synthesised phencyclidine or PCP. Domino studied PCP effects in animals and in 1958, Greifenstein made the first trials of PCP in humans under the name of Sernyl. Sernyl did not cause depression of cardiovascular and respiratory functions, but elicited severe excitation with a very prolonged postoperative recovery. Because of its psychedelic effects, it became a street drug under the name of 'angel dust' and was placed on schedule II of Federal Controlled Substance Act (CSA) in 1978...

BACKGROUND: 4-Thio-substituted phenethylamines (2C-T drugs) are potent psychedelics with poorly defined pharmacological properties. Because of their psychedelic effects, 2C-T drugs are sometimes sold as new psychoactive substances (NPSs). The aim of the present study was to characterize the monoamine receptor and transporter interaction profiles of a series of 2C-T drugs. METHODS: We determined the binding affinities of 2C-T drugs at monoamine receptors and transporters in human cells that were transfected with the respective receptors or transporters...

Psilocybin, the active compound in psychedelic mushrooms, is an agonist of various serotonin receptors. Seminal psilocybin positron emission tomography (PET) research suggested regional increases in glucose metabolism in frontal cortex (hyperfrontality). However, a recent arterial spin labeling (ASL) study suggests psilocybin may lead to hypo-perfusion in various brain regions. In this placebo-controlled, double-blind study we used pseudo-continuous ASL (pCASL) to measure perfusion changes, with and without adjustment for global brain perfusion, after two doses of oral psilocybin (low dose: 0...

The classic serotonergic hallucinogens, or psychedelics, have the ability to profoundly alter perception and behavior. These can include visual distortions, hallucinations, detachment from reality, and mystical experiences. Some psychedelics, like LSD, are able to produce these effects with remarkably low doses of drug. Others, like psilocybin, have recently been demonstrated to have significant clinical efficacy in the treatment of depression, anxiety, and addiction that persist for at least several months after only a single therapeutic session...

AIMS: This 11-month study analyzed illicit drug sales on the anonymous Tor network, with a focus on investigating whether a seller's reputation and capacity increased daily drug sales. DESIGN AND SETTING: The data were gathered from Silkkitie, the Finnish version of the Silk Road, by web crawling the site on a daily basis from (November 2014 to September 2015). The data include information on sellers (n=260) and products (n=3823). MEASUREMENTS: The measurements include the sellers' reputation, the sale amounts (in euros), the number of available products and the types of drugs sold...

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 predicted self-reported engagement in pro-environmental behaviors, and that this relationship was statistically explained by people's degree of self-identification with nature...

A resurgence of neurobiological and clinical research is currently underway into the therapeutic potential of serotonergic or 'classical' psychedelics, such as the prototypical psychedelic drug lysergic acid diethylamide (LSD), psilocybin (4-phosphoryloxy-N,N-dimethyltryptamine), and ayahuasca - a betacarboline- and dimethyltryptamine (DMT)-containing Amazonian beverage. However, the mechanisms of therapeutic action are still not fully explained. Given that an altered state of consciousness is a common denominator that characterizes all classical psychedelics and given that both rapid eye movement sleep (REMS) and psychedelics modulate perception, mental imagery, emotion activation, fear memory extinction, and sense of self and body, in the present article, these two states of consciousness are systematically compared, and therapeutically relevant conclusions are drawn based on available evidence...

This paper is an effort to describe, in neuroscientific terms, one of the most ambiguous concepts of the universe-the soul. Previous efforts to understand what the soul is and where it may exist have accepted the soul as a subjective and individual entity. We will make two additions to this view: (1) The soul is a result of uninhibited mental activity and lacks spatial and temporal information; (2) The soul is an undivided whole and, to become divided, the soul has to be reduced into unconscious and conscious mental events...

There is converging evidence that high doses of hallucinogenic drugs can produce significant alterations of self-experience, described as the dissolution of the sense of self and the loss of boundaries between self and world. This article discusses the relevance of this phenomenon, known as "drug-induced ego dissolution (DIED)", for cognitive neuroscience, psychology and philosophy of mind. Data from self-report questionnaires suggest that three neuropharmacological classes of drugs can induce ego dissolution: classical psychedelics, dissociative anesthetics and agonists of the kappa opioid receptor (KOR)...

Psilocybin and other 5-hydroxytryptamine2A agonist classic psychedelics have been used for centuries as sacraments within indigenous cultures. In the mid-twentieth century they were a focus within psychiatry as both probes of brain function and experimental therapeutics. By the late 1960s and early 1970s these scientific inquires fell out of favor because classic psychedelics were being used outside of medical research and in association with the emerging counter culture. However, in the twenty-first century, scientific interest in classic psychedelics has returned and grown as a result of several promising studies, validating earlier research...

Much of the history of pharmacology and therapeutics involves finding new uses for old drugs. The latest rediscovery is that of psychedelic drugs. Since they can cause profound distortions of perception and were once used as part of religious ceremonies, such research may seem unusual at this time.

For the past two years, I have taught a seminar on medical research scandals. The syllabus looks like a highlight reel of exploitation and abuse: children fed plutonium-laced breakfast cereal, prisoners dosed with the active ingredient in Agent Orange, mental patients given psychedelic drugs and massive electroconvulsive therapy before being sent into curare-induced paralysis and a coma. I designed the seminar to crush the idealism of future physicians by illuminating the dark patterns that research scandals typically follow...

Background: Ayahuasca is a plant tea containing the psychedelic 5-HT2A agonist N,N-dimethyltryptamine (DMT) and harmala monoamine-oxidase inhibitors. Acute administration leads to neurophysiological modifications in brain regions of the default mode network (DMN), purportedly through a glutamatergic mechanism. Post-acutely, ayahuasca potentiates mindfulness capacities in volunteers, and induces rapid and sustained antidepressant effects in treatment-resistant patients. However, the mechanisms underlying these fast and maintained effects are poorly understood...

The phenomenon of stupefying by the use of available over-the-counter drugs (OTC) among adolescents is an essential problem in both Poland and throughout the world. Popular analgesics, cold medicine and antihistamines contain psychedelic substances, such as dextromethorphan (DXM), pseudoephedrine/ephedrine, codeine (methylmorphine), dimenhydrinate, paracetamol (acetaminophren) and others. Cases of fatal addiction to dextromethorphan, one of the active substances contained in medicines, e.g., the common cold, have been reported...

BACKGROUND: New psychoactive substances (NPS) continue to emerge; however, few surveys of substance use ask about NPS use. Research is needed to determine how to most effectively query use of NPS and other uncommon drugs. OBJECTIVE: To determine whether prevalence of self-reported lifetime and past-year use differs depending on whether or not queries about NPS use are preceded by "gate questions." Gate questions utilize skip-logic, such that only a "yes" response to the use of specific drug class is followed by more extensive queries of drug use in that drug class...

Recent research suggests that functional connectivity changes may be involved in the pathophysiology of psychiatric disorders. Hyperconnectivity in the default mode network has been associated with psychopathology, but psychedelic serotonin agonists like psilocybin may profoundly disrupt these dysfunctional neural network circuits and provide a novel treatment for psychiatric disorders. We have reviewed the current literature to investigate the efficacy and safety of psilocybin-assisted therapy for the treatment of psychiatric disorders...
