Background: Psychedelic drugs have recently emerged as plausibly effective pharmacological agents for the management of depression, anxiety, and other neuropsychiatric conditions, including conditions that have not benefited from prior interventions. The latter half of the twentieth century marked a revolution in the treatment of depression, anxiety, and psy...
A growing body of work shows that autonomic signals provide a privileged evidence-stream to capture various aspects of subjective and neural states. This work investigates the potential for autonomic markers to track the effects of psychedelics - potent psychoactive drugs with important scientific and clinical value. For this purpose, we introduce a novel Ba...
This retrospective study presents the case of a young woman in her mid-twenties who suffered from insecurity and abandonment-related anxiety, which intensified after a breakup of her relationship. Her parents' alcoholism and schizophrenia, as well as emotional and physical violence, had been a part of her childhood, but they had appeared 'normal' to her. Her...
Major depressive disorder presents a substantial global health burden, and at least 30-40% of patients exhibit treatment resistance to antidepressants. Ketamine, an NMDA receptor antagonist, is used as an anesthetic agent. In 2019, the U.S. Food and Drug Administration (FDA) approved esketamine (the S-enantiomer of ketamine) as a therapeutic agent for treatm...
While a relatively large body of research exists on many aspects of psychedelic therapy, articles describing a complete, successful treatment process are rarely found. This article therefore presents a case of a woman in her early forties with early complex trauma due to domestic violence, sexual abuse and poverty in her childhood, resulting in approximately...
In medicine, psychedelics were initially considered as a tool for clinicians to understand psychotic states. Based on the presented case data, a reversal of that concept is proposed: psychedelics could be conceptualized as a tool for people chronically anxious and depressed since early childhood to understand ordinary states of mind (e.g. calmness, hopefulne...

Pets can have accidental, intentional, or malicious exposure to illicit drugs. It is a growing concern over the last decade because there is an increase in usage of illicit drugs in humans and diagnosis is difficult. Owners are often not aware of exposure, or they are reluctant to admit possession of recreational drugs in the household due to potential legal...
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 ef...
There is much excitement surrounding recent research of promising, mechanistically novel psychotherapeutics - psychedelic, anesthetic, and dissociative agents - as they have demonstrated surprising efficacy in treating central nervous system (CNS) disorders, such as mood disorders and addiction. However, the mechanisms by which these drugs provide such profo...
AimsInformation on time trends in use of different plant-based hallucinogens is lacking. The current study used nationally representative U.S. data to assess overall and age-specific time trends in the prevalence of lifetime and 12-month use of plant-based hallucinogens and dissociative agents.MethodsParticipants were respondents aged ≥ 12 years (N = 1,006,0...
Recent clinical and preclinical evidence points towards empathogenic and prosocial effects elicited by psychedelic compounds, notably the serotonin 5-HT2A agonists lysergic acid diethylamide (LSD), psilocybin, N,N-Dimethyltryptamine (DMT), and their derivatives. These findings suggest a therapeutic potential of psychedelic compounds for some of the behaviour...
Hallucinogens include many different drugs, which are often called “psychedelic” drugs. The US National Institute on Drug Abuse categorizes these drugs into 2 categories: classic hallucinogens and dissociative drugs. Both types of psychedelics can lead to hallucinations - sensations and images that seem real although they are imaginary. In addition, an indiv...
Long term benefits following short-term administration of high psychedelic doses of serotonergic and dissociative hallucinogens, typified by psilocybin and ketamine respectively, support their potential as treatments for psychiatric conditions such as major depressive disorder. The high psychedelic doses induce perceptual experiences which are associated wit...
Adolescence is a period of profound developmental changes, which run the gamut from behavioral and neural to physiological and hormonal. It is also a time at which there is an increased propensity to engage in risk-taking and impulsive behaviors like drug use. This review examines the human and preclinical literature on adolescent drug use and its consequenc...
ObjectiveThe relationship between ketamine's hallucinogenic- and dissociative-type effects and antidepressant mechanism of action is poorly understood. This paper reviewed the correlation between subjective effects defined by various psychometric scales and observed clinical outcomes in the treatment of patients with Major Depressive Disorder (MDD).MethodsBa...
Short-term moderate doses of serotonergic and dissociative hallucinogens can be useful in the treatment of anxiety. Recently, a trend has developed for long-term intermittent 'microdosing' (usually one-tenth of a 'full' active dose), with reports of long-lasting relief from anxiety and related disorders; however, there is no scientific evidence for the effic...
ObjectivesClassic psychedelics (serotonin 2A receptor agonists) and dissociative hallucinogens (NMDA receptor antagonists), though differing in pharmacology, may share neuropsychological effects. These drugs, however, have undergone limited direct comparison. This report presents data from a double-blind, placebo-controlled within-subjects study comparing th...
Methoxetamine (MXE), a ketamine analogue, is one of the new "legal highs" sold on the Internet. The aim of this qualitative study was to provide an initial understanding of what characterizes the experiences induced by MXE. Anonymously written reports (33 persons) on the effects of MXE were collected from public Internet forums and analyzed using the Empiric...
