Background: Psilocybin is a psychoactive compound found in hallucinogenic mushrooms and is rapidly dephosphorylated in vivo to psilocin, its pharmacologically active metabolite. Despite the growing clinical and scientific interest in these substances, information regarding their interaction with cytochrome P450 (CYP450) enzymes remains scarce, raising concer...
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...
S elective S erotonin R euptake I nhibitors (SSRIs) and two psychedelics, Psilocybin (4-phosphoryloxy-N,N-dimethyltryptamine), and MDMA (3,4-Methylenedioxymethamphetamine) act on serotonergic-related neural circuits and function as serotonin modulators. All three molecules are either currently used or proposed as novel therapeutic modalities to treat P ost- ...
ABSTRACT This paper examines the intimate relationship of affection, consumption, and ritual practice between humanity and mushrooms of the genus Psilocybe, focusing mainly on the Americas and Brazil. To this end, it uses reflections that present the American continent as a macroregion historically marked by transits, connections, and exchanges since pre-Col...
Detecting psilocybin use is challenging because it rapidly converts to its psychoactive metabolite psilocin, and both compounds are unstable in blood. Bufotenin, a structural isomer of psilocin, may exhibit comparable instability in blood. For reliable detection, we developed and validated an LC-MS/MS method to simultaneously quantify psilocin, bufotenin, an...
In Canada, the use of both prescription medications and psychedelics has become increasingly prevalent. As of 2022, approximately 16.5% of Canadians-about 6.3 million individuals-were prescribed at least one antidepressant, with fluoxetine remaining one of the most commonly used options (IQVIA, 2023). Benzodiazepine use, including drugs like alprazolam, rang...
INTRODUCTION: This article presents a narrative review of psilocybin-assisted psychotherapy as a promising intervention for addressing anxiety, depression and psycho-existential distress in patients with advanced cancer. This group of disorders, often resistant to conventional treatments, significantly impacts patients' quality of life and autonomy, as well ...
Psilocybin is a hallucinogen with complex neurobiological and behavioral effects. Underlying these effects are changes in brain neuroplasticity. We hypothesized psilocybin given during adolescence, a time of heightened neuroplasticity, particularly in the forebrain, would affect emotional behavior and the associated underlying neuroanatomy, neurocircuitry, a...
People with cancer often experience anxiety and depression following a diagnosis and can face barriers to accessing treatment for their mental health. An increasing number of patients are considering alternative approaches to managing their mental health symptoms, such as the psychedelic, psilocybin. A growing number of clinical trials show significant and e...
In our original case report we provide detailed accounts of two research participants who reported the emergence of spontaneously recovered, previously forgotten traumatic memories of sexual assaults during psilocybin treatment. In their commentary of this article, Kangaslampi et al. argue that we preemptively label the experiences as dissociated traumatic m...
BACKGROUND: Major depressive disorder (MDD) is the leading cause of disability worldwide, affecting roughly 322 million people. Recently, doses of psilocybin have shown promise in treating mood disorders, sparking interest in other dosing practices. According to anecdotal reports and observational studies, microdosing psilocybin yields benefits to mental hea...
We carried out a systematic review of modern-era (1990-2025) placebo-controlled studies assessing the acute and post-acute effects of lysergic acid diethylamide, dimethyltryptamine and psilocybin on cognitive and psychological functions. From February 28 to March 19, 2025, PubMed and APA PsychINFO were systematically searched for placebo-controlled studies e...
The therapeutic potential of psilocybin in treating psychiatric disorders has gained attention recently. While most research has focused on isolated psilocybin, evidence suggests that whole mushroom extracts exhibit greater efficacy, implicating a possible entourage effect of additional bioactive compounds. This study aimed to elucidate the holistic neuropha...
Psilocybin is the primary psychoactive compound in "magic mushrooms"; it has been used by humans for millennia, it is in promising clinical trials with humans and used in legalized psilocybin-assisted therapy, and researchers use and are further developing human-based methods with cutting-edge technologies.However, researchers are still allowed to conduct un...
Abstract Background and aims Despite growing popularity and increasing legal access, psychedelic therapy remains financially inaccessible to many. This study was designed to test the feasibility of conducting group psilocybin therapy in low-income adults with depression in Oregon's regulated psilocybin program. Methods An open label, uncontrolled design was ...
Anhedonia, a core symptom of depression, is often resistant to conventional treatments and significantly impacts quality of life. This secondary analysis aimed to evaluate the effects of psilocybin-assisted psychotherapy (PAP) on anhedonia severity in individuals with treatment-resistant depression (TRD). Participants (n = 30) with TRD and a primary diagnosi...
