Recent literature suggests potential associations between hallucinogen use and valvular heart disease (VHD) due to prolonged activation of serotonin 5-HT2B receptors, which may lead to valvular fibrosis - a condition also linked to drugs including fenfluramine and pergolide. Despite these concerns, epidemiological studies exploring this association are lacki...
Investigators will recruit 36 individuals on MAT for OUD for a double-blind, placebo-controlled design to determine whether PEX010 (25-mg/d) shows preliminary efficacy on neural correlates of neurocognition and on clinical outcomes. Participants will be randomized to either (single dose) 25-mg (PEX010-25 group) or 1-mg (PPEX010-1 group) PEX010 in a 2:1 ratio...
Introduction Psychoactive Psilocybe spp. mushrooms pose significant public health risks. We report a cluster of Psilocybe keralensis poisonings in Chengdu, China, highlighting its unique clinical features and cardiovascular complications.Case Series Four patients ingested 16-90 g of wild mushrooms (misidentified as an edible species, but later molecularly co...
Objective: Hallucinogen-persisting Perception Disorder (HPPD) is a rare condition characterized by the re-experiencing of one or more perceptual symptoms that an individual experienced while intoxicated with a hallucinogenic substance when the individual is sober. While there are several case reports of HPPD in adult patients, there is a scarcity of document...
Purpose: Self-inflicted penetrating orbital trauma is a rare ophthalmologic emergency requiring timely intervention and neurological monitoring to identify and treat any possible intracranial complications and to prevent irreversible vision loss. This case report aims to describe a fatal case of self-inflicted ocular trauma following the consumption of psilo...
Known for their capacity to alter perception and consciousness, psychedelics are increasingly being explored for therapeutic applications in treating conditions such chronic pain, major depressive disorder, and post-traumatic stress disorder.1,2 Despite historical stigmas and legal restrictions, recent changes in legislation and the United States Food and Dr...
Psychedelics like LSD (Lysergic acid diethylamide) and psilocybin are known to modulate perceptual modalities due to the activation of mostly serotonin receptors in specific cortical (e.g., visual cortex) and subcortical (e.g., thalamus) regions of the brain. In the visual domain, these psychedelic modulations often result in peculiar disturbances of viewed ...
HISTORY In the early part of twentieth century, these molecules were known as psychotomimetics, meaning that they create a state similar to psychosis. Later on, they were also termed as hallucinogens, but psychedelics usually do not cause hallucinations at a therapeutic dose. The name psychedelics for these substances was first given by Osmond in 1957, meani...
Clinical trials of psychedelics have provided support for their potential efficacy and safety. Although most combined a psychedelic with psychological support akin to psychotherapy, providing psychotherapy is costlier and more difficult to scale than providing only support to reduce harms. Trials with factorial designs can evaluate the individual effects of ...

Ketamine, a non-competitive NMDA inhibitor with significant psychedelic properties, is widely used in the management of acute and chronic pain. Ketamine is used intraoperatively to spare opioids and prevent acute and chronic postoperative pain; it is also used in patients with complex pain syndromes and patients with opioid tolerance. Medical cannabis is alr...

BackgroundLysergic acid diethylamide (LSD) and psilocybin are serotonergic hallucinogens that are used primarily for recreational abuse. Small studies evaluated the efficacy of LSD and psilocybin for several psychiatric conditions. There are limited safety or toxicity data for either of these substances, especially in large populations.MethodsThis was a retr...
BACKGROUND: The mechanisms of drug-induced visions are poorly understood. Very few serotonergic hallucinogens have been studied in humans in decades, despite widespread use of these drugs and potential relevance of their mechanisms to hallucinations occurring in psychiatric and neurological disorders. METHODOLOGY/PRINCIPAL FINDINGS: We investigated the mecha...
In this dissertation, I used theories of serotonin to understand the effects of serotonergic hallucinogens on visual perception and attention. I began by studying hallucinatory syndromes in drug users in Chapter 1. Despite long-standing reports of prolonged or reoccurring perceptual changes in a subset of hallucinogen users, very little is known about Halluc...
