Psilocybin-assisted therapy (PAT) has been shown in early trials to reduce the symptoms of treatment-resistant depression (TRD). This study evaluated the cost-effectiveness of PAT as a third-line treatment for major depressive disorder compared to standard of care (SOC). We used an individual-level, probabilistic simulation model that portrays representative...
Background: Post-traumatic stress disorder (PTSD) is a debilitating condition for which there are few efficacious treatments. Psilocybin is being studied for use in treatment-resistant depression but has not yet been investigated in PTSD. Aims: The trial’s primary outcome was to investigate the safety and tolerability of single-dose psilocybin in participant...
Established by the 1971 United Nations (UN) Convention on Psychotropic Substances, the prohibition of the recreational use of psychedelics (lysergic acid diethylamide [LSD], psilocybin, N, N -dimethyltryptamine [ N, N -DMT], and mescaline) has two premises. First, recreational use poses a serious threat to public health because psychedelics are highly liable...
Background: Cancer poses an existential threat for patients and caregivers. Psilocybin-assisted therapy (PAT) has emerged as a potential tool to meet these existential needs, yet little is known about how patients describe this element of their cancer journey, and how it might be affected by PAT, especially in the group therapy context. Purpose: To explore h...
IMPORTANCE: Psilocybin-assisted psychotherapy may offer a novel approach to treating depression, anxiety, and existential distress in individuals with life threatening illnesses, where current treatments show limited efficacy. OBJECTIVE: To evaluate the efficacy and safety of psilocybin-assisted psychotherapy versus active placebo and psychotherapy in adults...
Use of selective serotonin reuptake inhibitor (SSRI) antidepressants has been associated with reduced intensity of emotional experience. Conversely, some research has shown that use of psilocybin in patients with depression leads to an increase in responsiveness to emotional face stimuli, suggesting that the psychedelic generates a transient elevation in moo...
PurposeSpirituality is a core component of holistic cancer care, yet additional support is needed to understand and implement spirituality-focused interventions in practice. The aim of this review was to identify available interventions to address spirituality among people with cancer, to explore common components, and to examine efficacy across intervention...
This study will test the hypothesis that brain systems are differentially regulated by serotonin in individuals with and without Autism Spectrum Disorder. To do this, the brain response to two single acute doses of partial serotonin (5HT)1A/2A receptor agonist psilocybin (COMP360) relative to a single dose of placebo (baseline serotonin activity) will be com...
BACKGROUND AND AIMS: Psilocybin has emerged as a potential treatment for alcohol use disorder (AUD), but early efficacy data are inconsistent. Depression following alcohol detoxification significantly increases the risk of relapse. This pilot study aimed to evaluate the feasibility, acceptability, and preliminary efficacy of psilocybin-assisted psychotherapy...
There are few effective treatments for eating disorders (EDs), and new interventions are urgently needed. The MEDication and other drugs For Eating Disorders (“MED-FED”) survey investigated the lived experience of adults with EDs regarding their prescription and non-prescription drugs use. Psychedelic drugs were highly rated in this survey for their impact o...
Perception of visual contrast depends on the surrounding spatial context. Typically, the salience of a central target is reduced by a high contrast surrounding stimulus, an effect known as surround suppression. Although this phenomenon is well-studied, the role of specific neurotransmitter systems during surround suppression in human vision remains unclear. ...
Background: Although classic psychedelic trials show therapeutic potential, the limited diversity of participants raises concerns about generalizability and safety. Aims: This study assesses the representation of race, ethnicity, and sex in interventional clinical trials of psilocybin and lysergic acid diethylamide (LSD) to evaluate disparities in participan...
Abstract Psychedelic drug use is experiencing a global resurgence, both in clinical research and community settings. This paper presents a comprehensive public health analysis of the naturalistic use of psychedelics-defined as use outside clinical or research environments. Drawing on a review of 104 peer-reviewed articles, this analysis evaluates the mental,...
BACKGROUND: Obsessive-compulsive disorder (OCD) is a common and disabling condition. A large proportion of patients fail to respond to first-line treatment with serotonin reuptake inhibitors either selective serotonin reuptake inhibitors (SSRIs) or clomipramine. Preliminary evidence suggests psilocybin, a serotonin receptor agonist, might be efficacious. We ...
This systematic review and meta-analysis evaluates (1) the effectiveness of psychedelic-assisted therapy (PAT) using psilocybin and ketamine for psychosocial symptoms in adults with cancer, (2) contextualizes findings with non-randomized and exploratory studies of other psychedelics, and (3) examines the role of therapeutic frameworks in shaping outcomes. We...
Trauma-related disorders and substance use are disproportionately underdiagnosed and undertreated in individuals with High-Functioning Autism (Level 1 Autism Spectrum Disorder), particularly those in underserved or marginalized communities. Emerging evidence suggests that psychedelic-assisted therapies-including psilocybin, MDMA, and ketamine-offer promising...
Serotonergic psychedelics alter self-boundaries and can induce out-of-body experiences (OBEs)-the sense of being located outside one’s physical body. While OBEs also occur in clinical conditions and can be experimentally induced, their neural basis under psychedelics remains underexplored. In an open-label, baseline-controlled MRI study of 62 healthy adults ...
The use of drugs with psychedelic and dissociative effects for the treatment of psychiatric illnesses has become increasingly popular in recent years. However, few trials have been conducted to determine the efficacy of these agents in the specific setting of treatment-resistant major depressive disorder (MDD) in older adults. In this paper, we review notabl...
A recent randomized, double-blind, placebo-controlled, parallel-group trial (NCT02061293) found that psilocybin-assisted therapy significantly improved drinking outcomes compared to an active placebo in adults with alcohol use disorder (AUD). In this secondary analysis, we assessed whether psilocybin-assisted therapy improved self-compassion and whether thes...
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...
