Lysergic acid diethylamide (LSD) is a classic hallucinogen, widely abused for decades, while phencyclidine (PCP) has increased in popularity in recent years, especially among the adolescents. Very little is known about the general toxicity of these compounds, especially about their possible neurotoxic effects at the cell level. The aim of this study was to address these gaps by assessing the...

Abstract Introduction 25B-NBOH is a synthetic hallucinogen closely related to the “NBOMe” family of N-substituted 2C phenethylamine derivatives. There have been no published reports documenting the clinical toxicity of NBOH derivatives. Case series Five patients presented to the Emergency Department (ED) with altered conscious state following exposure to powder sold as “powdered LSD” at a...
Abstract Rationale LSD is the prototypical psychedelic. Despite a clear central role of the 5HT 2a receptor in its mechanism of action, the contributions of additional receptors for which it shows affinity and agonist activity remain unclear. Objectives We employed receptor-enriched analysis of functional connectivity by targets (REACT) to explore differences in functional connectivity (FC)...
Lysergic acid diethylamide (LSD) is a serotonergic psychedelic compound receiving increasing interest due to putative anxiolytic and antidepressant properties. However, the potential neurobiological mechanisms mediating these effects remain elusive. Employing in vivo electrophysiology, microionthophoresis, behavioral paradigms and morphology assays, we assessed the impact of acute and chronic...
In 1965, I was training in clinical toxicology in the pharmacology department of the University of California San Francisco (UCSF) and living in the Haight Ashbury. I studied various psychedelics, including LSD, mescaline, and ibogaine, in human and animal models. The psychedelics were then being used as a therapeutic drug in clinical settings and researched as a potential antipersonnel agent...
This chapter highlights the similarities in chemical structure and physiologic effects of hallucinogens, as well as their metabolism, therapeutic uses and potential for misuse or abuse. Special attention is given to the testing process, with an emphasis on interpretation of test results. Hallucinogens are drugs that alter an individual's perception of reality. The classic hallucinogens include...
Background: Classic psychedelics show promise in the treatment of mental health conditions; however, more scalable intervention protocols are needed to maximize access to these novel therapeutics. In this proof-of-concept study, perceptions of safety, subjective effects, and beliefs about the clinical utility of lysergic acid diethylamide (LSD) were evaluated among healthy participants ( N =...
Background: Classic psychedelics hold promise as therapeutics for psychiatric disorders, but require scalable intervention protocols. This proof-of-concept study evaluated the safety, tolerability, pharmacokinetics, and subjective effects of 50, 75, and 100 µg lysergic acid diethylamide (LSD) in healthy adults within a novel intervention paradigm. Methods: Up to three participants were...
Abstract Growing interest has been seen in using lysergic acid diethylamide (LSD) and psilocybin in psychiatric research and therapy. However, no modern studies have evaluated differences in subjective and autonomic effects of LSD and psilocybin or their similarities and dose equivalence. We used a double-blind, randomized, placebo-controlled, crossover design in 28 healthy subjects (14 women,...
Psychedelics extracted from plants have been used in religious, spiritual, and mystic practices for millennia. In 1957, Dr. Hofmann identified and synthesized the prodrug psilocybin, a substance present in more than 200 species of psychedelic mushrooms. Although there were limitations related to the scientific design of many studies, clinical observations performed during the 1950s and 1960s...

Hallucinogens, or psychedelics, are substances/drugs that have been used for over a millennium. The most well known are LSD, psilocybin, mescaline, and PCP. These substances may induce hallucinations as well as cause somatic and psychological symptoms. Because of the Controlled Substances Act of 1970, there has been very little research done to determine the long-term consequences or perhaps...
Background: Controversy surrounds psychedelics and their potential to boost creativity. To date, psychedelic studies lack a uniform conceptualization of creativity and methodologically rigorous designs. Aims: This study aimed at addressing previous issues by examining the effects of lysergic acid diethylamide (LSD) on creativity using multimodal tasks and multidimensional approaches. Methods:...
The resurgence of interest in using psychedelic drugs, including lysergic acid diethylamide (LSD), in psychiatry has drawn attention to the medically unsupervised practice of 'microdosing'. Thousands of users claim that very low doses of LSD, taken at 3-4-day intervals, improve mood and cognitive function., However, few controlled studies have described the effects of the drug when taken in...
Drugs that target the human serotonin 2A receptor (5-HT 2A R) are used to treat neuropsychiatric diseases; however, many have hallucinogenic effects, hampering their use. Here, we present structures of 5-HT 2A R complexed with the psychedelic drugs psilocin (the active metabolite of psilocybin) and d -lysergic acid diethylamide (LSD), as well as the endogenous neurotransmitter serotonin and the...
Abstract Background LSD and psilocybin are increasingly used in phase I trials and evaluated as therapeutic agents for mental disorders. The phenomenon of reoccurring drug-like experiences after the acute substance effects have worn off was described for both substances and especially attributed to LSD. According to the DSM-V, the persisting and distressing manifestation of these experiences is...
Dear Editor, We are in the midst of a so-called “psychedelic renaissance,” a time of renewed interest in the therapeutic potential of psychoactive drugs such as psilocybin, mescaline, and lysergic acid diethylamide. When they first emerged as topics of academic interest in the mid-20th century, these substances were greeted with exuberance for their apparent panacea-like effects in treating a...
RationaleA broad reassessment of the potential benefits of psychedelic drugs has led to the initiation of multiple major clinical trials in an effort to advance their status to become FDA-approved medications, as well as local legislative efforts to legalize or decriminalize their use.ObjectivesTo use recently published data to assess potential risks and benefits of psychedelic drugs as...
Fibromyalgia (FM) is a difficult to treat chronic pain condition for which there is strong interest in alternative treatments. There is growing interest in the potential of psychedelic substances (e.g., psilocybin) in conjunction with psychotherapy to treat chronic pain. Via a cross-sectional, anonymous, online survey, we aimed to characterize knowledge, perceptions, and past use of...
The therapeutic potential of psychedelics in headache and chronic pain disorders is documented over decades of anecdotal and early investigational reports, which have paved the way for the first controlled studies of psilocybin and lysergic acid diethylamide (LSD) in these disorders. The reported lasting clinical effects after limited dosing with psychedelics present a novel means for disease...
