Nicotine dependence remains a leading cause of preventable mortality worldwide. Pharmacotherapy and behavioral interventions offer modest efficacy with limited long-term success. Psilocybin-assisted psychotherapy (PAP) is an emerging approach to nicotine cessation with a growing evidence base. As PAP research expands, understanding how nicotine users’ attitu...
Psilocybin-containing mushrooms, commonly known as magic mushrooms, strongly affect mood, cognition, and behavior. Psilocybe azurescens is a species of psilocybin mushrooms that contains the main active compounds psilocybin and psilocin. Psilocybin mushrooms have been used since ancient times to improve the quality of life. However, their adverse effects hav...
Psychotic symptoms are uncommon and non-specific adverse effects of classic (serotonergic) psychedelics such as lysergic acid diethylamide (LSD), psilocybin, and mescaline. They can emerge during the acute phase of psychedelic drug effects, persist into the subacute ("afterglow") period, or, in rare cases, develop into long-term psychotic illness. Across all...
Depression is a complex and globally prevalent mental disorder, for which conventional antidepressant medications face limitations such as delayed onset and insufficient efficacy. Classic psychedelics, most notably psilocybin, have recently emerged as promising candidates for treatment of depression and demonstrated rapid, robust, and sustained antidepressan...
Background: Psychedelic-assisted psychotherapy has shown promising results for treating alcohol use disorder (AUD) and other mental health conditions. Although the precise mechanisms of psychedelic therapies remain unclear, many studies report increased feelings of connectedness following psychedelic experiences. Specifically, both nature relatedness (one’s ...
This Phase 2a clinical trial is an open-label, single-group, within-subjects pilot study designed to evaluate the safety, feasibility, and preliminary efficacy of psilocybin as a therapeutic intervention for adults with developmental stuttering. This pilot study will assess whether further research to explore the potential benefits of psilocybin-assisted the...
BACKGROUND AND AIMS: There is an urgent unmet need for novel treatments for methamphetamine (MA) use disorder. We explored the qualitative experiences of people participating in a study of psilocybin-assisted psychotherapy (PAT) to treat MA use disorder. DESIGN AND SETTING: Qualitative study of participants enrolled in a single arm, open-label pilot study of...
The CAnadian Network for Psychedelic-Assisted Cancer Therapy (CAN-PACT) was launched in 2025 to address urgent gaps in supportive care for Canadians with cancer experiencing demoralization syndrome (loss of meaning, dysphoria, disheartenment, helplessness, a sense of failure) and related psychosocial distress. CAN-PACT has six major objectives: (1) to develo...
Eating disorders (ED) remain challenging to treat, with high dropout and low remission rates in cognitive-behavioral therapy for EDs (CBT-ED). Psilocybin treatment (PT) demonstrates therapeutic potential to enhance CBT-ED by exerting several neurobiological, psychological, and experiential effects (e.g., antidepressant, neuroplasticity, emotional openness) t...
Introduction: Major depressive disorder (MDD) affects over 21 million adults in the U.S (NIMH, 2023) and remains a significant public health challenge. Despite the effectiveness of traditional medications, 30% of patients remains resistant. Little is known about the beliefs individuals hold regarding novel treatments, such as psilocybin and the motivations b...
The overall objective of this study is to assess the feasibility, safety and preliminary efficacy of psilocybin-assisted therapy to alleviate opioid-refractory pain in patients with advanced-cancer. The name of the study intervention used in this research study is: Psilocybin (a tryptamine derivative) This study is a phase 2 open label, single center, concur...
BACKGROUND: Obsessive-compulsive disorder (OCD) is a debilitating mental disorder commonly treated with selective serotonin reuptake inhibitors, atypical antipsychotic augmentation and cognitive-behavioural therapy. However, up to 60% of people with OCD do not respond to these treatments. Therefore, a novel intervention, psilocybin-assisted psychotherapy (PA...
Abstract Psilocybin has demonstrated promising antidepressant effects in depression and treatment-resistant depression (TRD) in controlled clinical trials. However, its effectiveness and safety in real-world therapeutic settings remain largely unknown. Although psilocybin is not yet approved as an antidepressant treatment, Switzerland’s unique legal framewor...
The global demographic shift toward aging populations has intensified the need for innovative therapeutic interventions targeting late-life mental health conditions, notably depression, loneliness, and existential distress. Traditional pharmacological treatments often exhibit limited efficacy and poor tolerability in older patients, primarily due to age-rela...
Approximately 20% of young people experience self-harm behaviour in their lives. Self-harm can occur across different mental health disorders, and lead to negative outcomes and risk of suicide. Current treatments are long, costly and do not suit all young people, making it essential to research alternative treatments. Therapy combined with psychedelic drugs ...
Abstract Early maladaptive schemas (EMS) are highly prevalent in patients seeking psychedelic-assisted psychotherapy and correlate strongly with baseline depression and anxiety. This study characterized EMS in 192 adults and longitudinally followed 74 patients receiving psilocybin- or LSD-assisted therapy. We found that baseline schema burden, particularly r...
This randomised controlled feasibility trial evaluates the Digital Intervention for Psychedelic Preparation (DIPP), a novel 21-day self-guided program designed to prepare individuals for psychedelic experiences. Forty healthy volunteers will be randomly assigned to either a meditation-based intervention or a music-based control condition. Both groups will fo...
Background: Psilocybin-assisted psychotherapy (PAP) may be an effective intervention for a range of mental disorders. However, there appears to be a relative lack of qualitative evidence to complement emerging quantitative findings. To our knowledge, no reviews have systematically mapped the literature on qualitative studies on PAP for the treatment of menta...
Psilocybin, a naturally occurring psychedelic compound, has received attention as a novel therapeutic option for major depressive disorder (MDD), particularly in cases where traditional treatments prove ineffective. The study aims to evaluate psilocybin's therapeutic potential by examining its efficacy, safety, and mechanisms of action as well as addressing ...
