The purpose of this study is to understand whether people with Parkinson's Disease and depression have improvement in their symptoms after psilocybin therapy. This is a randomized controlled trial of oral psilocybin therapy for depression in people with Parkinson's disease (PD). The primary goal is to examine efficacy of psilocybin therapy in this patient po...
Background: Psychedelics are emerging as potential management options for chronic musculoskeletal pain due to preliminary evidence of effectiveness and low addictive potential, but patients’ perceptions remain unknown. This study assessed patient perceptions regarding psilocybin for musculoskeletal pain. Methods: We conducted a cross-sectional survey of adul...
BACKGROUND AND AIMS: There has been a resurgence of interest in using psilocybin to treat various mental health conditions. Although some adults in the United States (US) are using psilocybin, little is known about the epidemiology of its use, especially for microdosing (i.e., taking a fraction of a regular dose). This study aimed to present nationally repre...
The goal of this laboratory study is to establish whether and which microdoses of psilocybin are safe to administer at home to healthy participants. Eligible participants will be given ascending doses of psilocybin trihydrate and a single, interspersed, randomized placebo on separate days in double-blind fashion. The participants will be asked to complete qu...
Abstract IMPORTANCE Microdosing psilocybin may be a novel treatment for major depressive disorder (MDD). OBJECTIVE Assessing the antidepressant effects and safety of repeated low doses of psilocybin in participants diagnosed with MDD. DESIGN This was a Phase II, randomized, double-blind, placebo-controlled clinical trial. SETTING The trial was conducted from...
BACKGROUND: Psychological distress is a common problem near the end of life, for which we lack effective, timely and scalable treatments. No previous study has assessed whether microdose psilocybin can improve symptoms in this population. AIM: To determine whether microdose psilocybin is safe, feasible and potentially efficacious in a palliative setting. DES...
About 30-50% of patients with advanced illness experience depression, anxiety, or decreased sense of purpose and autonomy. Together, these are called psychological distress. Treatment options such as medication and therapy are available; however, they do not always work and can be time-consuming and expensive. We need treatments that work well, quickly, and ...
Participants in this study will undergo a series of non-invasive tests and activities designed to understand how a single dose of psilocybin might influence cognition and emotional well-being in healthy older adults. After providing written informed consent, eligible participants, aged between 60 and 85, will be randomly assigned to receive a dose of psilocy...
Repeated self-administration of small doses of psychedelics, known as microdosing, has been associated with perceived improvements in psychological functioning. However, few studies have examined effects at the daily level. Drawing on data from a naturalistic, prospective, international survey of adults who microdose (N = 1435), we assessed self-reported wit...
The goal of this clinical trial is to test the feasibility of combining meditation with psilocybin microdosing in healthy adults. The main questions it aims to answer are: 1. Recruitment and retention feasibility 2. Acceptability, Safety and Tolerability 3. Exploratory Measures: 3.1: Explore potential changes in sleep quality and duration, heart rate variabi...
Motives are a highly influential force in substance use and vary depending on the substance or dose being used. Little research has compared motives across different doses of psilocybin. Psilocybin is often ingested in microdoses (0.1-0.4 g) or macrodoses (1 g+), each producing unique perceptual and mood effects. The current study examined whether motives fo...
Executive function deficits, common in psychiatric disorders, hinder daily activities and may be linked to diminished neural plasticity, affecting treatment and training responsiveness. In this pioneering study, we evaluated the feasibility and preliminary efficacy of psilocybin-assisted frontal-midline theta neurofeedback (NF), a neuromodulation technique l...
Some recent research and commentary have suggested that most or all the effects reported by people who microdose psychedelics may be explained by expectations or placebo effects. In this rapid review, we aimed to evaluate the strength of evidence for a placebo explanation of the reported effects of microdosing. We conducted a PubMed search for all studies in...

Some recent research and commentary have suggested that most or all the effects reported by people who microdose psychedelics may be explained by expectations or placebo effects. Here we step through all the available evidence from dose-controlled studies that have investigated the effects of low doses of LSD and psilocybin. We suggest eight reasons why curr...

This study is seeking to find the optimal microdose or low dose of psilocybin (magic mushrooms) that provides general enhancements to mood, memory, sleep, and other measures of general well-being without any hallucinogenic effects. Psilocybin is a natural psychoactive alkaloid component of more than 200 species of naturally growing mushrooms that can be foun...
Microdosing is the practice of regularly using very low doses of psychedelic drugs. Anecdotal reports suggest that it may enhance well-being, creativity and cognition. Here, we use data from a self-blinding microdose trial, a large (n=240) placebo-controlled citizen science trial of microdosing to investigate whether tolerance develops during microdosing. We...
