2-Linoleoylglycerol Is a Partial Agonist of the Human Cannabinoid Type 1 Receptor that Can Suppress 2-Arachidonolyglycerol and Anandamide Activity Leanne Lu, Gareth Williams, and Patrick Doherty Cannabis and Cannabinoid Research, 2019, Volume X, Number X Doi : 10.1089/can.2019.0030 Abstract Introduction : The cannabinoid type 1 (CB1) receptor and cannabinoid type 2 (CB2) receptor are widely expressed in the body and anandamide (AEA) and 2-arachidonoylglycerol (2-AG) are their best characterized endogenous ligands. The diacylglycerol lipases (diacylglycerol lipase alpha and diacyl-glycerol lipase beta) not only synthesize essentially all the 2-AG in the body but also generate other monoacylglycerols, including 2-linoleoylglycerol (2-LG). This lipid has been proposed to modulate endocannabinoid [...]

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 [...]

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 suiteEntheogens — Sacramentals or Sacrilege ? (a working draft for a syllabus) Thomas ROBERTS in "Roberts, B. Thomas. (editor) (2012). 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. Grinspoon and Bakalar, Psychedelic Drugs Reconsidered Are we experiencing a reorganization in Western religions now, [...]

Richards New York, NY: Columbia University Press, 2016. 269 pp. ISBN 978-0-231-17406-0 $29.95 Reviewed by Michael J. Winkelman http://dx.doi.org/10.1037/a0040299 Abstract Reviews the book, Sacred knowledge: Psychedelics and religious experiences, by William A. Richards. Richards’s career of clinical research with psychedelics and professional formation in theology, comparative religion and the psychology of religion bring integrative perspectives to understanding psychedelic experiences. Clinical accounts, scientific research and his personal experiences with psychedelics enable Richards to address issues of core importance in religious studies, medicine and society in general. Clinical studies with psychedelics provide findings that contribute to assessment of [...]

Looking towards the future, researchers at Miami University have used genetic engineering to coax harmless E. coli bacteria to produce psilocybin. Psilocybe semilanceata. Credit: Pixabay. The mushrooms that produce psilocybin, such as Psilocybe cubensis, are not particularly expensive or difficult to grow. However, they do take up a lot of space and require many [...]

Chung Mo Koo, Hoon-Chul Kang Journal of Epilepsy Research, 2017, 7, 16-20. pISSN 2233-6249 / eISSN 2233-6257 www.kes.or.kr Epilepsy is an important disease that affects brain function, particularly in those under 3 years old. Uncontrolled seizures can affect cognitive function and quality of life. For these reasons, many trials have been conducted to investigate treatments for pediatric epilepsy. Currently, many antiepileptic drugs are available for the treatment of epilepsy, but cases of intractable epilepsy continue to exist. In the past, cannabis has been tested as a potential treatment of intractable epilepsy. Since [...]

Doblin, Merete Christiansen, Lisa Jerome, Brad Burge JOURNAL OF PSYCHOACTIVE DRUGS, 2019, VOL. 51, NO. 2, 93–97 https://doi.org/10.1080/02791072.2019.1606472 ABSTRACT Psychedelic plants and fungi have been used in indigenous medicinal traditions for millennia. Modern psychedelic research began when Albert Hofmann first synthesized lysergic acid diethylamide (LSD-25) in 1938. Five years later, became the first person to ingest LSD. Hofmann was unaware of the significance of his actions, and the effects they would set in motion. After a burgeoning period of scientific and cultural exploration in the1950s and ‘60s, psychedelic research was [...]
