Background About 15 years ago, a diverse group of new recreational psychotropic substances began to emerge, which were marketed for example as “legal highs,” “research chemicals,” or “designer drugs.” These substances were later subsumed under the label “Novel Psychoactive Substances” (NPS). Important NPS classes are cathinones, synthetic cannabimimetics, phenethylamines, and herbal drugs. The...

After a two-decade hiatus in which research on psychedelics was essentially halted, placebo-controlled clinical trials of psychedelic-assisted therapy for mental health conditions have begun to be published. We identified nine randomized, placebo-controlled clinical trials of psychedelic-assisted therapy published since 1994. Studies examined psilocybin, LSD (lysergic acid diethylamide),...

BACKGROUND: Hallucinogenic mushrooms are fungi that contain the substance psilocybin. When ingested, psilocybin can induce hallucinations, euphoria, and alterations in the perception of space and time. Ingestion of hallucinogenic mushrooms may result in adverse effects. OBJECTIVE: The objective of this study was to describe hallucinogenic mushroom misuse reported to poison centers. METHODS:...

Modern day research, in an attempt to determine the potential therapeutic and adverse effects of illicit substances, is a growing field, but one that faces many regulatory challenges. Due to the potential abuse of illicit substances such as Cannabis, 3,4-methylenedioxymethamphetamine (MDMA), lysergic acid diethylamide (LSD) and psilocybin, regulations have been conceived with the intent of...

Although research findings to date do not support the use of psychedelic compounds in the treatment of psychiatric disorders, the existing body of research justifies continued investigation, a literature review concludes. The review found the most significant evidence supporting use of psilocybin and 3,4‐methylenedioxymethamphetamine (MDMA). Both of these drugs have been given “breakthrough...

The regular consumption of very small doses of psychedelic drugs (known as microdosing) has been a source of growing media and community attention in recent years. However, there is currently limited clinical and social research evidence on the potential role of microdosing as therapies for mental and substance use disorders. This paper examined subjective experiences of microdosing...

Serotonergic hallucinogens such as lysergic acid diethylamide (LSD) induce head twitches in rodents via 5-HT2A receptor activation. The goal of the present investigation was to determine whether a correlation exists between the potency of hallucinogens in the mouse head-twitch response (HTR) paradigm and their reported potencies in other species, specifically rats and humans. Dose-response...

Significance In a technical tour de force, we have created a framework demonstrating the underlying fundamental principles of bidirectional coupling of neuronal and neurotransmitter dynamical systems. Specifically, in the present study, we combined multimodal neuroimaging data to causally explain the functional effects of specific serotoninergic receptor (5-HT 2A R) stimulation with psilocybin...

Background: Microdosing psychedelics – the practice of taking small, sub-hallucinogenic doses of substances like LSD or psilocybin-containing mushrooms – is becoming increasingly popular. Despite its surging popularity, little is known about the effects of this practice. Aims: This research had three main aims. First, we attempted to replicate previous findings regarding the subjective benefits...
