Background: This systematic review and meta-analysis evaluates the efficacy and safety of psilocybin-assisted psychotherapy (PAP) for adults with major depressive disorder (MDD). Methods: A PROSPERO-registered search (CRD42024561979) of CENTRAL, Scopus, PsycINFO, and MEDLINE (2010-2024) identified clinical trials assessing PAP. Risk of bias was assessed usin...
Importance: Psilocybin has been proposed as a rapid-acting antidepressant (onset 6 weeks), but evidence from randomized clinical trials remains limited, particularly in the broader major depressive disorder (MDD) population. Objective: To assess short-term and long-term antidepressant effects of psilocybin therapy in patients with MDD. Design, Setting, and P...
PURPOSE OF REVIEW: There is growing evidence that psychedelics and associated treatment modalities may offer therapeutic benefits across a range of psychiatric conditions. Anorexia nervosa (AN), a serious and often treatment-resistant illness associated with significant morbidity and mortality, is one such condition for which psilocybin-assisted therapy (PAT...
Importance: Psilocybin shows promise in treating depression, although limitations of previous research warrant further research. Objective: To investigate the efficacy and safety of oral psilocybin, 25 mg, with adjunct psychotherapy in treatment-resistant depression (TRD). Design, Setting, and Participants: This was a 2-center, triple-blinded (investigator, ...
BACKGROUND: Current treatments for obsessive-compulsive disorder (OCD), including serotonin reuptake inhibitors and cognitive-behavioral therapy, are often insufficient. Psilocybin, a 5HT2a agonist psychedelic, has shown promise for treating OCD, but rigorous evidence is still needed. AIMS: This randomized clinical trial evaluated safety, tolerability, and b...
Abstract Lyme disease, caused by the bacterium Borrelia burgdorferi, is the most common vector-borne disease in the United States and Europe. Although antibiotics effectively treat most cases, an estimated 10-20% of patients develop post-treatment Lyme disease (PTLD), a chronic syndrome marked by fatigue, pain, cognitive difficulties, mood disturbance, and r...
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 ...
Background: Psilocybin is a promising therapy for cancer-related distress, but existing individual treatment models are resource intensive. In this study, we designed and tested a group model of psilocybin therapy for people with metastatic cancer and cancer-related anxiety and depression. Method: Eligibility criteria included metastatic cancer, moderate-to-...
Background: Emotional distress is often comorbid with serious illness, especially in individuals facing social stigmas, such as patients with HIV. Death acceptance may serve as a protective factor against such distress. Standard psychopharmacologic interventions have shown insufficient results in alleviating distress associated with serious illness. Prelimin...

Although the mainstay treatment of BD consists of pharmacotherapy with mood stabilizers and atypical antipsychotics, a large proportion of patients with BD depression do not respo...
BACKGROUND & AIMS: There are few effective treatments for methamphetamine use disorder, despite increasing global demand. Here, we assessed the safety and feasibility of outpatient psilocybin-assisted psychotherapy for methamphetamine use disorder. DESIGN: Single arm, open label pilot study. SETTING: Outpatient public stimulant treatment program at St. Vince...
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...
Psychedelic-assisted therapy (PAT) involves supported experiences with psychedelic medicines in carefully curated environments. Early evidence suggests possible utility of PAT for addressing psychosocial-spiritual-existential concerns, yet gaps remain in understanding findings related to PAT's role in palliative care. This rapid review aims to synthesize cur...
Psychedelic-assisted therapy is gaining recognition for its potential to enhance human functioning. While most research has focused on psychedelic' therapeutic use for mental illness, this review applies the PERMA Theory of Well-Being to systematically examine their role in enhancing well-being in healthy individuals. The final search of five academic databa...
ObjectivesMood disorders and existential distress impact those with cancer or a serious illness at higher rates than the general population. There have been limited pharmacological advances in recent years, and available psychological interventions vary in degree of impact and durability as a treatment modality in this population. A recent renaissance in psy...
People living with cancer (PLWC) often face profound existential distress that is insufficiently addressed by conventional psychosocial supports. This qualitative study explored PLWC's attitudes, beliefs, and experiences regarding psychedelic-assisted therapy (PAT) as a novel approach to addressing psychosocial suffering, particularly existential distress. F...

The goal of this multi-centre phase I/II open-label, single-arm study is to determine the safety, feasibility, therapeutic dose, and preliminary efficacy of psilocybin microdosing to treat psychological distress among patients with advanced illness. Forty patients will receive psilocybin drug product (1-3mg per day, Mon-Fri) for 4 weeks to be administered vi...
