The primary purpose of this study is to preliminarily determine if the use of psilocybin to promote abstinence from methamphetamine is feasible and well tolerated in populations such as those found in Northern Louisiana. Investigators will assess the impact of psilocybin-facilitated treatment on methamphetamine abstinence, craving, negative affect, cognitive...
Psilocybin, a serotonin receptor agonist in the brain, significantly and quickly improves depressive symptoms while inducing profound acute subjective effects. The benefit-risk ratio of psilocybin in treatment-resistant depression seems favorable, but needs to be confirmed. Moreover, the role of 5-HT2A receptors, involved in the psychedelic experience, on th...

The goal of this clinical trial is to test psilocybin in combination with mindfulness training in healthy adults. The main question it aims to answer is "Does mindfulness training enhance the effects of psychedelic therapy (psilocybin) on mental health?" Interested individuals will complete an initial eligibility session and eligible participants will then b...
The purpose for this study is to observe the real world experience of participants who are receiving psilocybin in the context of (alcoholism) Alcohol Use Disorder without intervening in the model of care. The study team will engage directly with the participants to examine the outcomes in participants who have been deemed eligible and appropriate to receive...
Rationale: Recent evidence shows that Lysergic Acid Diethylamide (LSD), even when administered in low, non-hallucinogenic doses, can produce analgesic effects and improve pain tolerance in a sample of healthy volunteers. Such results complement what was already observed with other serotonergic psychedelics such as psilocybin: survey studies and case series i...
About one in three people with major depression respond poorly to standard antidepressant treatments. This kind of depression is called treatment-resistant depression, and it can lead to long-term disability, financial challenges, and a higher risk of suicide. Psilocybin-a compound found in certain mushrooms-has shown early promise as a new treatment for thi...
This is an open-label psilocybin-assisted therapy study that will examine the safety and tolerability of psilocybin-assisted therapy in the offspring of genocide survivors with mood and anxiety disorders. The study will also investigate the efficacy of psilocybin-assisted therapy in reducing symptoms such as depression, anxiety and stress, as well as changes...
This study is a phase 2 single-site, double-blind, placebo-controlled, randomized clinical trial with an open-label extension phase to examine the safety of psilocybin (25 mg) combined with psychological support (Psi-PS) for treatment of approximately 40 military veterans and first responders (ages 21-65) with co-occurring alcohol use disorder (AUD) and post...
Safety, Tolerability, pharmacokinetics and efficacy of a single administration of COMP360 in participants with recurrent Major Depressive Disorder. This is a phase II, multi-centre, randomised, double-blind, controlled study. The study population will include participants aged ≥18 years with recurrent Major Depressive Disorder (MDD) with up to four prior tre...
This study will examine the effect of a single high dose of psilocybin therapy (30 mg) versus a very low dose (1 mg) as an adjunctive therapy to individuals undergoing standard-of-care outpatient buprenorphine treatment for Opioid use disorder (OUD). The participants will have previously undergone buprenorphine induction before. Effects of adjunctive psilocy...
In previous clinical trial work, the investigators observed lasting reductions in headache burden after limited dosing of psilocybin. This purpose of this study is to examine potential sources for this observed effect. This study will measure brain resting state functional connectivity (fMRI), central synaptic density (SV2A PET), peripheral markers of inflam...
The purpose of the study is to assess the safety and acceptability of up to two sequential administrations of 25 mg psilocybin with additional therapeutic support in decreasing suicidality in patients with Bipolar Disorder (BD II) depression. This study aims to determine whether psilocybin paired with psychotherapy is a safe, feasible, and acceptable treatme...
To compare the physiological and psychological effects of psilocin taken orally by pill or sublingually by dissolving a tablet under the tongue to those of psilocybin taken by pill in healthy adults. The primary goal of this study is to compare the physiological and psychological effects of psilocin taken orally by pill or sublingually dissolved under the to...
This study will examine the synaptotrophic effects of psilocybin among medically healthy, detoxified OUD subjects. Eligible OUD participants will undergo pre- and post- psilocybin administration PET scans with the \[11C\]-UCB-J radiotracer while inpatient. Participants will undergo screening as outpatients at the Clinical Neuroscience Research Unit (CNRU). O...
Psilocybin (active compound of "magic mushrooms") is a prototypical psychedelic substance that acts via agonism on serotonin (5-HT) 2A receptors. Psilocybin is rapidly metabolized into its active metabolite psilocin. Psilocybin is currently under investigation as potential treatment for various neuropsychiatric disorders. Psilocybin is also widely used for r...
This study will examine the effects of a single dose of psilocybin, administered with psychological support, on symptoms of depression. It will also assess whether different post-dosing interventions, including a non-invasive technique called transcutaneous auricular Vagus Nerve Stimulation (taVNS), influence various psychological and behavioral outcomes. In...
