This study will examine the effect of a single high dose of psilocybin therapy (30 mg) versus a very low dose (1 mg) as an adjunctive therapy to individuals undergoing standard-of-care outpatient buprenorphine treatment for Opioid use disorder (OUD). The participants will have previously undergone buprenorphine induction before. Effects of adjunctive psilocy...
BackgroundClassic serotonergic psychedelics are 5-HT2A partial agonists that induce non-ordinary states of consciousness. Many have demonstrated anti-addictive properties; however, their impact on smoking behaviors remains under-researched. This review provides a synthesis of the therapeutic potential of these compounds in promoting smoking cessation and red...
Psilocybin, the naturally occurring psychedelic compound produced by hallucinogenic mushrooms, has received attention due to considerable clinical evidence for its therapeutic potential to treat various psychiatric and neurodegenerative indications. However, the underlying molecular mechanisms remain enigmatic, and few studies have explored its systemic impa...
Serotonergic psychedelics alter self-boundaries and can induce out-of-body experiences (OBEs)-the sense of being located outside one’s physical body. While OBEs also occur in clinical conditions and can be experimentally induced, their neural basis under psychedelics remains underexplored. In an open-label, baseline-controlled MRI study of 62 healthy adults ...
Background: Alcohol Use Disorder (AUD) is a chronic pathological condition with significant burdens throughout the world. Despite the effectiveness of the current pharmacological treatments, the ongoing issues with AUD and the high relapse rates necessitate the exploration of innovative therapies, including the use of psychedelic drugs, which have shown prom...
Psilocybin (PSIL) is a psychedelic drug and a promising experimental therapeutic for many psychiatric conditions. Precision functional mapping (PFM) combines densely repeated resting state fMRI sampling and individual-specific network mapping to improve signal-to-noise ratio (SNR) and effect size in brain imaging research. We present a randomized cross-over ...
Objective Despite many decades of experimental studies and clinical trials involving a variety of psychedelic agents, we still lack a comprehensive understanding of the effects of these substances on psychological experiences. As such, we designed and conducted a study to comprehensively characterise the effects of both psilocybin and 3,4-Methylenedioxymetha...
Psilocybin (active compound of "magic mushrooms") is a prototypical psychedelic substance that acts via agonism on serotonin (5-HT) 2A receptors. Psilocybin is rapidly metabolized into its active metabolite psilocin. Psilocybin is currently under investigation as potential treatment for various neuropsychiatric disorders. Psilocybin is also widely used for r...
Background: Despite significant advancements in the treatment of depression, challenges such as inadequate response rates and high placebo effects highlight the need for improved therapies and a deeper understanding of treatment expectations. Patient expectations play a crucial role in treatment outcomes but have not been systematically investigated in the c...

Background: Although historical writings, anthropological accounts, and experimental studies document associations between psilocybin use and religion, no prospective experimental study has investigated how the effects of psilocybin are experienced and interpreted by religious clergy. This exploratory study evaluated the overall safety and the acute and endu...
Psychedelic compounds significantly reshape conscious perception, yet the implications of these alterations for complex visual-guided behaviors remain poorly understood. We investigated how psilocybin modulates visual salience processing during natural scene perception. Twenty-three participants completed eye-tracking tasks under self-blinded low and high do...
BACKGROUND: Opioid use disorder (OUD) is a debilitating health condition that is associated with significant morbidity and mortality in the U.S. While preliminary studies have demonstrated that psilocybin is associated with lowered odds of OUD, current research in this domain suffers from a lack of investigation into the impact of race/ethnicity on this asso...
Abstract PcncAAAD is a calcium-activatable noncanonical aromatic L-amino acid decarboxylase (AAAD) featuring a unique appendage C-terminal domain (CTD) and two metal-binding sites. In this study, we establish an in silico RMSD-based evaluation model through molecular dynamics simulations, validated by in vitro enzyme assays, to decipher the enzyme’s calcium ...
Clinical trials using full doses of psychedelics have provided preliminary evidence supporting their safety and efficacy in treating a variety of physical and psychological conditions. Anecdotal reports indicate that even very small amounts of these substances may provide therapeutic benefits, though robust clinical studies are still needed. This chapter rev...
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...
Psychedelics can profoundly alter consciousness by reorganising brain connectivity; however, their effects are context-sensitive. To understand how this reorganisation depends on context, we collected and comprehensively analysed the largest psychedelic neuroimaging dataset to date. Sixty-two adults were scanned with functional MRI and EEG during rest and na...
IntroductionA substantial number of patients exhibit treatment-resistant depression (TRD), posing significant challenges to clinicians. The discovery of novel molecules or mechanisms that may underlie TRD pathogenesis and antidepressant actions is highly needed.Areas coveredUsing the PubMed database, the authors searched for emerging evidence of novel approa...
