Heaven and Hell Revisited, Peter Webster, 1996

Heaven and Hell Revisited Peter Webster Composed in 1996 for The Psychedelic Library   How is it possible for two persons of such obvious intellectual talent as William Braden and Aldous Huxley to have such radically different experiences as a result of ingestion of a similar quantity of mescaline? Both Huxley and Braden brought to their first psychedelic experiment a wide knowledge and understanding of science, religion, mysticism, literature and fine arts, yet Huxley’s initial psychedelic experience was a revelation, and led to the writing of The Doors of Perception, a book which launched a movement, if not a revolution. William Braden’s experiment, recounted [...]

Psilocybine mindfulness training modulates self-consciousness and brain default mode network connectivity with lasting effects, SMIGIELSKI Lukasz et al., 2019

Psilocybine mindfulness training modulates self-consciousness and brain default mode network connectivity with lasting effects SMIGIELSKI Lukasz, SCHEIDEGGER Milan, KOMETER Michael, VOLLENWEIDER Franz X. NeuroImage, 2019, 196, 207-215 Doi : 10.1016/j.neuroimage.2019.04.009   A B S T R A C T Both psychedelics and meditation exert profound modulatory effects on consciousness, perception and cognition, but their combined, possibly synergistic effects on neurobiology are unknown. Accordingly, we conducted a randomized, double-blind, placebo-controlled study with 38 participants following a single administration of the psychedelic psilocybin (315 μg/kg p.o.) during a 5-day mindfulness retreat. Brain dynamics were quantified directly pre- and post-intervention by functional magnetic resonance imaging during the resting state and [...]

Cannabis Withdrawal, Nicolas J. Schlienz and Ryan Vandrey, 2019

Cannabis Withdrawal Nicolas J. Schlienz and Ryan Vandrey I. D. Montoya, S. R. B. Weiss (eds.), Cannabis Use Disorders, https://doi.org/10.1007/978-3-319-90365-1_11   Introduction Drug withdrawal refers to a constellation of symptoms that occur following abrupt cessation of chronic drug use. Though drug withdrawal can occur from stopping use of medication, it is most often encountered within the context of illicit, non-medicinal, drug use. The withdrawal symptoms that emerge following extended and frequent use of abused drugs are a key feature of what define substance use disorders [4, 85]. Further, there is accumulating neurobiological evidence that withdrawal drives the maintenance of problematic substance misuse through a mechanism of [...]

Psychedelic Elephant, Peter Webster, 2019

Psychedelic Elephant A critique of psychedelic research Peter Webster juillet 2019 https://www.researchgate.net/search.Search.html?type=researcher&query=Psychedelic%20Elephant   My title might lead some who are old enough to remember the incident 1 2 to expect from this essay an indictment of the idiots who conducted the "scientific research" during which an elephant was clearly murdered.3 It is always great fun to expose foolishness and willful ignorance. But unfortunately, psychedelic research in those days, the 1950s and 1960s, attracted no small number of other scientists who, at least in retrospect, could also be called idiots. Jean Houston (1967) has described one of her initial observations of LSD administration. The subject was told by [...]

Integrating Psychedelic Medicines and Psychiatry : Theory and Methods of a Model Clinic, Jordan Sloshower, 2018

Chapter 7 : Integrating Psychedelic Medicines and Psychiatry : Theory and Methods of a Model Clinic Jordan Sloshower In : Labate B., Cavnar C. (eds) : Plant Medicines, Healing and Psychedelic Science,  2018 © Springer International Publishing AG 2018 DOI: 10.1007/978-3-319-76720-8_7   Abstract The past two decades has seen a significant increase in both popular and scientific interest in psychedelic substances and plants as therapeutics for mental illness, addictions, and psychospiritual suffering. Current psychiatric practice privileges a biological paradigm in which the brain is considered the locus of mental illness and symptom-focused treatments are delivered to patients as passive recipients. In contrast, a psychedelic healing paradigm, constructed [...]

Expanding the Scientific Study of Self-Experience with Psychedelics, Manesh Girn and Kalina Christoff, 2018

Expanding the Scientific Study of Self-Experience with Psychedelics Manesh Girn and Kalina Christoff Journal of Consciousness Studies, 2018, 25, (11–12), 131–54 Abstract : The nature of the self has long been a topic of discussion in philosophical and religious contexts, and has recently also garnered significant scientific attention. Although evidence exists to suggest the multifaceted nature of self-experience, the amount of research done on each of its putative components has not been uniform. Whereas selfreflective processing has been studied extensively, non-reflective aspects of self-experience have been the subject of comparatively little empirical research. This discrepancy may be linked to the methodological difficulties in experimentally [...]

The Influence of Psychedelic Induced Ego-Dissolution on Self-Compassion, Kevin Allan Stansbury, 2019

The Influence of Psychedelic Induced Ego-Dissolution on Self-Compassion Kevin Allan Stansbury B.A., 2011, California State University, Dominguez Hills, May 2019 A THESIS Presented to the School of Social Work California State University, Long Beach In Partial Fulfillment of the Requirements for the Degree Master of Social Work   Abstract Prior research has shown that psychedelic induced ego-dissolution mediates therapeutic outcomes and enhances well-being. The experience of psychedelics has been shown to increase certain mindfulness capacities. A cross-sectional descriptive study was implemented in an online community to examine the relationship between psychedelic induced ego-dissolution and self-compassion in adults who have used psychedelics in the past. This study also [...]

The “Endless Trip” among the NPS Users : Psychopathology and Psychopharmacology in the Hallucinogen-Persisting Perception Disorder. A Systematic Review, Laura Orsolini et al., 2017

The “Endless Trip” among the NPS Users : Psychopathology and Psychopharmacology in the Hallucinogen-Persisting Perception Disorder. A Systematic Review Laura Orsolini, Gabriele Duccio Papanti, Domenico De Berardis, Amira Guirguis, John Martin Corkery and Fabrizio Schifano Frontiers in Psychiatry, 2017, Vol. 8, article 240 doi: 10.3389/fpsyt.2017.00240   Hallucinogen-persisting perception disorder (HPPD) is a syndrome characterized by prolonged or reoccurring perceptual symptoms, reminiscent of acute hallucinogen effects. HPPD was associated with a broader range of LSD (lysergic acid diethylamide)-like substances, cannabis, methylenedioxy-methamphetamine (MDMA), psilocybin, mescaline, and psychostimulants. The recent emergence of novel psychoactive substances (NPS) posed a critical concern regarding the new onset of psychiatric symptoms/syndromes, including cases [...]

Functional Connectivity Measures After Psilocybin Inform a Novel Hypothesis of Early Psychosis, Robin L. Carhart-Harris et al., 2012

Functional Connectivity Measures After Psilocybin Inform a Novel Hypothesis of Early Psychosis Robin L. Carhart-Harris, Robert Leech, David Erritzoe, Tim M. Williams, James M. Stone, John Evans, David J. Sharp, Amanda Feilding, Richard G. Wise, and David J. Nutt Schizophrenia Bulletin, 2012 doi: 10.1093/schbul/sbs117   model of psychosis. This study measured the effects of psilocybin on resting-state network and thalamo-cortical functional connectivity (FC) using functional magnetic resonance imaging (fMRI). Fifteen healthy volunteers received intravenous infusions of psilocybin and placebo in 2 task-free resting-state scans. Primary analyses focused on changes in FC between the default-mode- (DMN) and task-positive network (TPN). Spontaneous activity in the DMN is orthogonal [...]
