Hallucinogen Persistent Perception Disorder Induced by New Psychoactive Substituted Phenethylamines; A Review with Illustrative Case Cornel N. Stanciu and Thomas M. Penders Current Psychiatry Reviews, 2016, Vol. 12, No. 2, 1-3. DOI: 10.2174/1573400512666160216234850 Abstract : Hallucinogen Persistent Perception Disorder (HPPD) is considered an “uncommon” disorder described in association with use of hallucinogens such as LSD, mescaline and psilocybin. Despite multiple mentions of persistence of visual disturbances reported by users on online forums, clinicians may not be aware of this complication. There have been few descriptions of HPPD in association with use of new psychoactive substances (such as 2C-E). Increasing use of these designer stimulants places [...]

Richards Sacred Knowledge: Psychedelics and Religious Experiences Columbia University Press, New York, 2016, 244 pp. Hardback ISBN: 978-0-231-17406-0 Journal of Psychedelic Studies, 2018 Doi : 10.1556/2054.2018.003 With an extreme range of terms for psychedelic drugs – from “schizotoxic” to “entheogenic” – “psychedelic,” nonetheless remains the most salient one. These substances manifest or disclose aspects of the mind of those who take them as well as the mind of those who study them. Proponents for the innumerable terms for these drugs are all able to adduce supportive evidence. Necessarily, this evidence is a subjective experience, [...]

Mehta NeuroImage, 2019, 195, 252–260 https://doi.org/10.1016/j.neuroimage.2019.04.007 A B S T R A C T One of the main limitations of pharmacological fMRI is its inability to provide a molecular insight into the main effect of compounds, leaving an open question about the relationship between drug effects and haemodynamic response. The aim of this study is to investigate the acute effects of 3,4-methylene-dioxymethamphetamine (MDMA) on functional [...]
Lire la suitePsilocybin exerts distinct effects on resting state networks 1 associated with serotonin and dopamine in mice Joanes Grandjean, David Buehlmann, Michaela Buerge, Hannes Sigrist, Erich Seifritz, Franz X. Vollenweider, Christopher R. Pryce, Markus Rudin Preprint · September 2019 Doi : 10.1101/751255 Abstract Hallucinogenic agents have been proposed as potent antidepressants; this includes the serotonin (5-HT) receptor 2A agonist psilocybin. In human subjects, psilocybin alters functional connectivity (FC) within the default-mode network (DMN), a constellation of inter-connected regions that is involved in self-reference and displays altered FC in depressive disorders. In this study we investigated the effects of psilocybin on FC in the analogue of the [...]

Webster, pp. 1 - 36 © 2007 Nova Science Publishers, Inc. Abstract The drug 3,4-methylenedioxymethamphetamine (MDMA; Ecstasy) long has been considered a neurotoxin selective for serotonin (5-hydroxytryptamine; 5-HT) axons in rats and nonhuman primates. MDMA is also thought to have the potential to cause persistent serotonergic alterations in humans. Since the serotonin system is involved in the regulation of anxiety, researchers have proposed that recreational Ecstasy users may be at risk for the development of anxiety disorders and symptoms.

Lire la suiteA History of Drug Use : Mind-Altering Drugs in Social Context Eric Shepperd January 21, 2017, 26 p. It seems that an intrinsic property of consciousness is a desire to alter itself. The natural world is full of tools for changing the functioning of the mind, and both humans and nonhuman animals have used many different drugs throughout history. Some are derived directly from plant or animal sources, while others are refined extracts, or synthesized by purely chemical methods. Many of the drugs in use today are applied primarily for physiologically therapeutic purposes, while others have primarily psychological components, or a combination thereof. Psychoactive [...]

James Fadiman, Sophie Korbe et les « micro-doses » Vittorio Biancardi Chimères, 2017/1 N° 91 | pages 139 à148 Les programmes de recherche qui ont été menés légalement sur des dizaines de milliers de patients, à partir de la moitié du vingtième siècle, ont démontré qu’un usage soigneusement réduit de lsd peut se révéler efficace contre certaines psychopathologies, et bénéfique pour le développement personnel et spirituel. En outre, de récentes études ont mis en évidence que la prise de petites doses de lsd peut permettre entre autres une augmentation des capacités cognitives chez des sujets [...]
Lire la suiteLe microdosage de substances psychédéliques : bref historique et nouveaux axes de recherche Vittorio Biancardi Revue CIRCE, 2019, 11, Résumé Le micro-dosage est un phénomène social de plus en plus répandu parmi la communauté des consommateurs et consommatrices des substances dites psychédéliques. Il consiste une consommation d’un dixième de la dose typique de substance (principalement LSD ou Psilocybine) de façon fréquente, deux ou trois fois par semaine, pour améliorer les capacités cognitives ou comme auto-thérapie. L’analyse de ce phénomène est actuellement très fragmentaire et inconsistante, tant du point de vue des sciences humaines que du point de vue des sciences dites «dures». L’objectif de [...]

Spiritual Growth with Entheogens" To most people who are even moderately experienced with entheogens, concepts such as awe, sacredness, eternity, grace, agapé, transcendence, transfiguration, dark night of the soul, born-again, heaven, and hell are more than theological ideas; they are experiences. Introduction to Entheogens: Sacramentals or Sacrilege? It should not be necessary to supply more proof that psychedelic drugs produce experiences that those who undergo them regard as religious in the fullest sense.
