The integration of psychedelics and music in therapeutic settings is gaining recognition for its potential to enhance mental health outcomes. This review synthesizes current evidence on the neurobiological mechanisms underlying this synergy, focusing on receptor-level pathways (e.g., 5-HT2A receptor agonism, BDNF-TrkB signaling) and neural circuit dynamics (e.g., default mode network...
Ancient contemplative traditions offer sophisticated technologies for cultivating stable states of consciousness underlying sustainable well-being. This integrative review synthesizes empirical and theoretical literature on Patañjali’s Sanyam—the integrated practice of Dharana (concentration), Dhyana (meditative absorption), and Samadhi (non-dual awareness)—and its Zen parallel, Joriki...
Mainstays of pharmacoepidemiology are large, representative, behavioral surveys, which focus on many drugs with few detailed behaviors. Smaller, targeted studies measure drug-specific patterns but without explicit generalizability assumptions; the evidence generated is narrow. In this cross-sectional survey study, we outline an estimation framework based on data fusion and combine two surveys:...
Polysubstance use involving psychostimulants and opioids is increasingly prevalent and associated with elevated overdose risk, relapse vulnerability, and poor treatment outcomes. However, the neurobehavioral consequences of opioid-stimulant use remain poorly understood. We evaluated whether repeated methamphetamine-fentanyl polysubstance treatment disrupts social preference during withdrawal,...
Psilocybin simultaneously holds six contradictory legal classifications across jurisdictions: Schedule I (US federal), Breakthrough Therapy (FDA), legal therapeutic use (Oregon, Colorado), Schedule 8 medical use (Australia), and pending rescheduling review (DEA/HHS). This regulatory fragmentation constitutes a classification cascade—a multi-stage disruption propagated through administrative,...
Background: Psilocybe cubensis mushrooms contain the tryptamines psilocybin and psilocin, which are recognized for their therapeutic potential in mental health [1]. Additionally, due to their psychedelic effects, these mushrooms are also used for religious and recreational purposes. The increasing use of these tryptamines and other psychoactive substances has led to regulatory measures,...
This article reviews the current clinical evidence for psilocybin and ayahuasca as therapeutic agents, examining data from over 134 registered clinical trials and key publications in the New England Journal of Medicine, JAMA, JAMA Psychiatry, and Nature Neuroscience. The review addresses four dimensions: (1) the state of clinical evidence for psilocybin and ayahuasca in major depression and...
Major Depressive Disorder (MDD) and chronic pain are independently debilitating conditions that frequently co-occur. This comorbidity poses a significant clinical challenge, resulting in greater symptom severity, higher disability, and worse prognosis than either condition alone. Current therapies often address each disorder in isolation, leaving individuals with comorbid MDD and chronic pain...
Human neurons derived from stem cells show increased structural complexity and stronger synaptic connections after exposure to psilocin, the active metabolite of the psychedelic psilocybin.
CONTEXT: People living with serious illness frequently experience intense existential suffering related to awareness of finitude. Psychedelic-assisted therapies have been associated with reductions in death anxiety and existential distress, yet the experiential processes underlying transformations in the relationship with finitude remain insufficiently understood. OBJECTIVES: To synthesize...
