This study aims to study the feasibility of psilocybin therapy for patients with Amyotropic Lateral Sclerosis (ALS) with depressed mood. The secondary objective is to assess its impact on depression, quality of life, hopelessness, and functional status in this patient population. The proposed research's primary objective is to study the feasibility of psiloc...

Recent psychedelic patent activity highlights a strategic shift from experiential framing toward chemically and pharmacokinetically precise neurotherapeutics. Four recent patent applications collectively span solid-state control of psilocybin, exposure-shaped intramuscular and infusion-based dosing, and chemically diversified monoaminergic scaffolds with def...
This double-blind placebo-controlled pilot study seeks to investigate whether psilocybin can be safely administered to people with chronic phantom limb pain (PLP) in a supportive setting with close follow-up, and its effects on pain symptoms and other moods, attitudes, and behaviors. The investigators' primary hypotheses are that psilocybin is safe to admini...

IntroductionMental health disorders such as depression are a rising issue among university students. Some of them use complementary and alternative medicine (CAM) as self-administered therapy instead of or together with professional care. Defining the scale of the problem, its underlying reasons and possible implications are crucial for addressing it in clin...
Abstract Psilocybin is studied as innovative medication in anxiety, substance abuse and treatment-resistant depression. Animal studies show that psychedelics promote neuronal plasticity by strengthening synaptic responses and protein synthesis. However, the exact molecular and cellular changes induced by psilocybin in the human brain are not known. Here, we ...
Novel psychoactive substances (NPS) remain an ongoing challenge for public health, forensic laboratories, and regulatory agencies, especially when they are chemically related to controlled tryptamines but are marketed as legal alternatives. In the United States, the Federal Analogue Act (FAA) was intended to restrict such substances; however, regulatory loop...
Psychedelics are a diverse class of psychoactive compounds that profoundly alter perception, cognition, and emotional states. Recently, classical serotonergic agents, such as psilocybin and lysergic acid diethylamide (LSD), along with atypical agents such as methylenedioxymethamphetamine (MDMA, ecstasy) and ibogaine, have attracted renewed attention due to t...
BackgroundPsilocybin has shown rapid and sustained antidepressant effects in patients with major depressive disorder, yet the neurobiological mechanisms underlying these outcomes remain unclear.AimsThis study aimed to bridge clinical and preclinical findings by investigating the relationships between 5-HT2A receptor occupancy (RO) achieved after administrati...

The resurgence in research with classic psychedelics (e.g. LSD, psilocybin) underscores their potential for improved well-being; however, the interpersonal context and mechanisms of psychedelic impacts remain unknown. In a sample of 798 participants (81 couples), this survey study tested whether use of a psychedelic with a romantic partner (v. not together) ...
IntroductionPsychoactive mushroom edibles are gaining popularity, yet little is known of their clinical effects. These unregulated products are widely available, often with unlisted ingredients and inconsistent formulations, underscoring the need for more research to address public health concerns. We aimed to investigate recent trends in demographics and cl...
BACKGROUND: The claustrum, a subcortical structure densely expressing 5-hydroxytryptamine 2 A (5-HT2A) receptors, has been implicated in sensory integration, emotional regulation, salience, and attention. Despite its hypothesized involvement in the effects of serotonergic psychedelics, the neurochemical impact of these substances on claustral neurotransmissi...
Bipolar disorder affects approximately 40 million individuals worldwide, with depression being the most prominent phase of the illness. Owing to limited treatment options, bipolar depression remains a major public health concern, often causing significant functional impairment and increased suicide risk. Current therapies frequently lack rapid effectiveness,...
Binge Eating Disorder (BED) is the most prevalent eating disorder and is associated with psychiatric comorbidities, health impairments, and decreased quality of life. Emerging evidence suggests that psilocybin-assisted therapy may promote cognitive and emotional flexibility and disrupt maladaptive behavioral patterns, making it a promising candidate for BED ...
Production of the psychoactive compound psilocybin is a defining feature of the genus Psilocybe, commonly referred to as “psychedelic mushrooms”. However, Psilocybe fuscofulva is a striking exception within Psilocybe sensu stricto as it lacks the stereotypical blue bruising characteristic of the genus, and psilocybin has not been detected in the species.To i...
Anxiety disorders are chronic health conditions affecting the quality of life of millions of people. Psilocin, the active moiety of psilocybin, provides an anxiolytic effect; however, when orally administered as psilocybin, it only offers a moderate level of bioavailability and less predictable pharmacokinetics, potentially making effects after absorption va...
IntroductionPsilocybin may effectively treat psychological distress in cancer patients. A meta-analysis assessed its safety and effectiveness in this context.MethodsA comprehensive search across six databases (Scopus, PsycINFO, PubMed, Cochrane, CINAHL Complete, and Web of Science) was conducted to identify studies on psilocybin's effects on mental health in...
ImportanceThe availability of psychedelic retreats has grown to meet the demand for access to these substances. Despite centuries of use among Indigenous communities, psychedelics can pose serious risks for some users.ObjectiveTo determine safety precautions that retreat organizations that offer psychedelic substances currently use.Design, setting, and parti...
ImportancePsychedelic-assisted therapy (PAT) is a novel intervention for depressive symptoms, typically delivered with additional psychological therapy sessions. Quantitative evidence on how this concomitant therapy contributes to treatment outcomes is limited, highlighting the need for a systematic synthesis.ObjectiveTo evaluate whether the quantity of psyc...
The distinct subjective effects that define psychedelics such as lysergic acid diethylamide (LSD), psilocybin, or 1-(2,5-dimethoxy-4-iodophenyl)-2-aminopropane (DOI) as drug class are causally linked to the activation of the serotonin 2A receptor (5-HT2AR). However, some aspects of 5-HT2AR pharmacology remain elusive, such as what molecular drivers different...
