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 using RoB 2 for randomized controlled...

Recent studies have shown promising results for psychedelics in the treatment of psychiatric disorders. Both in clinical and recreational settings, contextual elements, such as music, can influence the experience of users and may be linked to positive outcomes. This systematic review identifies how music is being selected and used in psychedelisc-assisted psychotherapy (PAP). The search adopted...

Stable, high-level biosynthesis of complex natural products requires precise control of heterologous pathway expression, yet transcriptional architectures optimized on plasmids often fail when transferred to the chromosome. Here, we present ePathIntegrate, a genome-centric pathway engineering strategy that leverages CRISPR-associated transposases (CASTs) to integrate and rebalance multigene...

As jurisdictions across the U.S. consider enacting policies that facilitate access to psychedelics, they must determine how the desire to expand access to these substances should be weighed against the need to adequately protect safety. Oregon's psilocybin services program offers an important early case study of this balance in practice. Under the Psilocybin Services Act, adults over 21 are...

Traumatic brain injury (TBI) causes persistent neurobehavioral deficits and increases the risk of psychiatric disorders, including depression, anxiety, and cognitive dysfunction linked to disrupted neuroplasticity, neuroinflammation, and serotonergic (5-HT) signaling. No effective pharmacotherapies exist for chronic TBI. Psilocybin, a psychedelic 5-HT2A receptor agonist, shows promise due to...

Abstract Psilocybin and other serotonergic psychedelics show therapeutic promise for psychiatric disorders, yet objective neural correlates linking the acute psychedelic state to persisting psychological outcomes remain limited. Electroencephalography (EEG) microstate analysis characterizes the rapid spatiotemporal organization of large-scale brain activity, offering a millisecond-resolution...

Interest in psychedelics has expanded beyond clinical treatment contexts, yet little empirical work has examined how users describe psychedelic use in relation to sport and physical activity. This study conducted a qualitative content analysis of Reddit discussions involving psychedelics and physical performance. A Reddit search for “sports psychedelics” returned 253 threads. After screening,...

Psilocybin is a chemical compound found in certain types of hallucinogenic mushrooms, known as magic mushrooms. Evidence has shown potential therapeutic effects of psilocybin on different neuropsychiatric disorders such as major depressive disorder (MDD), posttraumatic stress disorder (PTSD), anxiety disorders, and obsessive-compulsive disorder (OCD). Although the efficacy of psilocybin in...

Attention-deficit/hyperactivity disorder (ADHD) is a prevalent neurodevelopmental condition in which prenatal stress and long-lasting disruptions of excitatory-inhibitory (E/I) balance have been implicated as key vulnerability factors. Although established pharmacological and behavioral treatments are effective for many individuals, they are not universally successful and do not directly target...

Background: Understanding the benefits of psychedelic-assisted therapy (PAT) will require scientific attention to the causal interaction between the therapeutic context and process. Measuring what actually happens during PAT in large-scale studies will be an essential component of this work. Objective: We aim to develop and preliminarily evaluate the feasibility and reliability of a direct...

Psilocybin has demonstrated promise for improving depressive symptoms in treatment-resistant depression, but its effects on anxiety, quality of life, functioning, and posttraumatic stress symptoms are less well studied. This study reports exploratory findings from an open-label trial in Veterans with TRD. Participants received a single 25-mg dose of psilocybin administered with psychological...

Background/Objectives: Psilocybin-assisted therapy (PAT) is a promising intervention to alleviate existential distress among patients with advanced cancer receiving palliative care. However, evidence on how to integrate PAT into routine oncology and palliative care services remains scarce. This study aimed to examine real-world PAT implementation, identify factors influencing adoption, and...

Classical serotonergic psychedelics, such as psilocybin, show emerging evidence of therapeutic potential across a range of mental health disorders, including depression, anxiety, and substance use disorders, with indications of transdiagnostic efficacy. While early-phase studies yielded encouraging results, recent larger-scale phase 3 trials, such as those evaluating psilocybin for...

Psilocybin, the main psychoactive compound in Psilocybe cubensis mushrooms, has gained considerable attention for its therapeutic potential. Current research focuses only on isolated psilocybin, neglecting the broader pharmacological and cultural use of the whole mushroom. This perspective advocates for an integrative approach that includes standardised P. cubensis extracts within the...

Introduction Treatment-resistant depression (TRD) remains a major clinical challenge, with limited efficacy of available therapies. Psilocybin, a serotonergic psychedelic, has shown promising antidepressant effects. As recent studies have shown altered default mode network activity following psilocybin administration, further neuroimaging research in clinical populations is needed to clarify...

Introduction Research on psychedelic compounds has grown quickly in the past decade. Yet molecule-specific, quantitative summaries are scattered, making it hard to see how interest differs by compound or over time. Objectives To quantify PubMed-indexed publications on ketamine, lysergic acid diethylamide (LSD), N,N-dimethyltryptamine (DMT), psilocybin, and psilocin; to describe annual trends...

A single dose of psilocybin may provide rapid relief for people with major depressive disorder (MDD), with benefits emerging within days and lasting for several weeks, according to a randomized clinical trial published May 15 in JAMA Network Open . Researchers of the study, “Short‐Term and Late‐Term Effects of Psilocybin on Symptoms in Major Depression: A Randomized Clinical Trial,” found that...

BACKGROUND: Several recent trials indicate positive effects of psilocybin in patients with major depressive disorder. However, questions need to be addressed regarding the relationship between dosage and therapeutic outcomes, such as the recommended dose range and frequency for optimal practice as well as the dose-dependent adverse effects. OBJECTIVE: (1) to assess the effectiveness and...

For English, the validated part of Psychedelic Experience Scale (PES48) is a four-factor structure called the Mystical Experience Questionnaire (MEQ30). The other validated part of the PES48 consists of four more factors: two more mystical factors (paradoxicality and connectedness, which together with the MEQ30 form the MEQ40), and two more non-mystical factors (visual experience and...

Clinical trials suggest that a single dose of psilocybin may be an effective treatment for substance use disorders. Choice impulsivity is a value-based decision-making bias that predicts drug-intake escalation and is commonly associated with substance use disorders. The dorsomedial prefrontal cortex regulates choice impulsivity and is enriched with 5-HT2A receptors that mediate effects of...
