Set, setting, preparation, and integration are widely recognized as important dimensions of psychedelic experiences. However, these concepts often remain too general to specify how preparation, containment, and aftercare should differ across substances, routes of administration, acute duration, residual effects, bodily condition, and interaction exposure. This article proposes the...
Abstract Psychedelic substances such as psilocybin, LSD, ayahuasca, DMT, or mescaline, when employed with knowledge and skill, can sometimes lead to profoundly meaningful and transformative subjective experiences. This chapter discusses how the predictive processing theory can further our understanding of these deeply meaningful spiritual psychedelic experience. It makes a more specific...

Major depressive disorder is a highly burdensome psychiatric condition worldwide, and many patients do not achieve full remission after standard monoaminergic antidepressant treatment. This has contributed to growing interest in rapid-acting antidepressant interventionstargeting neurobiological pathways beyond traditional serotonin, norepinephrine, and dopamine mechanisms. This review...
Classic psychedelics, including psilocybin, LSD, DMT, 5-MeO-DMT, mescaline, and phenethylamines such as DOI, exert their core effects through 5-HT2A receptor agonism, inducing widespread neurobiological and behavioral changes relevant to psychiatric research. Emerging evidence suggests that these effects are modulated by sex, yet this dimension remains underrepresented in studies. This review...
A resurgent therapeutic frontier, the contemporary renaissance in psychedelic science has accelerated investigation of classic serotonergic psychedelics (psilocybin, lysergic acid diethylamide (LSD), N,N-dimethyltryptamine (DMT), mescaline), empathogenic entactogenic agents (3,4-methylenedioxymethamphetamine (MDMA)), and glutamatergic dissociatives (ketamine) as adjuncts to psychotherapy. While...
Classic psychedelics such as lysergic acid diethylamide (LSD), psilocybin, N,N-dimethyltryptamine (DMT), and mescaline induce lasting changes in neuroplasticity and behavior that extend far beyond their acute pharmacological effects. Emerging evidence highlights that these enduring therapeutic benefits in neuropsychiatric conditions may be significantly mediated through complex epigenetic...

INTRODUCTION Given the contrasting results available in the literature, the objective of this systematic review was to investigate the specific impact of illicit use of classic psychedelics (psilocybin, LSD, DMT, mescaline) on suicidality (suicidal ideation, suicide planning, suicide attempts, suicides). METHOD According to PRISMA criteria, a systematic review of the literature was carried out...
With growing research on the use of psychedelics to treat mental health conditions, greater attention to the psychosocial procedures accompanying substance administration is warranted. This scoping review aims to categorize psychosocial protocols used in research involving psychedelics as psychiatric treatment according to their purpose, denomination, format, therapeutic orientation,...
Prophetic or messianic states of consciousness are charged with moral urgency and are active, historical, political, and sometimes infused with ego. In this paper, I inquire into psychedelic micro-messianic phenomenology and revolutionary dynamics through the historical case studies of Allen Ginsberg, Master Irineu, and John Wilson (Moonhead)—figures associated with the diffusion of LSD, Daime...
