Dream over life : Psychedelic terphenyl derivative induce hallucination via cannabinoid receptor 1, F.A. Fauzi et al., 2018

Dream over life : Psychedelic terphenyl derivative induce hallucination via cannabinoid receptor 1 F.A. Fauzi, M.S. Goh, S.A.T.T. Johari, F. Hashim, M.F.N. Hassim The International Fundamentum Sciences Symposium 2018 IOP Publishing IOP Conf. Series: Materials Science and Engineering 440 (2018) 012045 doi:10.1088/1757-899X/440/1/012045   Abstract. For ages, natural psychedelic resources have been used by ancient tribes for religious inspiration. In modern medicine, these compounds were prescribed to relieve severe distress and depression on cancer patients. Despite medical benefit, abuse of these compounds have become prevalent in our modern society. These compounds usually interacted withcannabinoid receptor 1 (CNR1) on neuron cell causing hallucination, and on other cell-types. In this [...]

Deconstructing Ecstasy : The Politics Of MDMA Research, Charles S. Grob, 2000

Deconstructing Ecstasy : The Politics Of MDMA Research Charles S. Grob Addiction Research, 2000, 8, 6, 549-588 http://dx.doi.org/10.3109/16066350008998989   What is Ecstasy? Defined by the New Webster’s Dictionary as a state of intense overpowering emotion, a condition of exultation or mental rapture induced by beauty, music, artistic creation or the contemplation of the divine, ecstasy derives etymologically from the ancient Greek ekstasis, which means flight of the soul from the body. The anthropologist, Mircea Eliade, who explored the roots of religious experience in his book Shamanism: Archaic Techniques of Ecstasy, has described the function of this intense state of mind among aboriginal peoples. Select individuals [...]

Epigenetic Effects of Cannabis Exposure, Henrietta Szutorisz and Yasmin L. Hurd, 2016

Epigenetic Effects of Cannabis Exposure Henrietta Szutorisz and Yasmin L. Hurd Biological Psychiatry, 2016, 79, 7,  586–594. doi:10.1016/j.biopsych.2015.09.014. Abstract The past decade has witnessed a number of societal and political changes that have raised critical questions about the long-term impact of marijuana (Cannabis sativa) that are especially important given the prevalence of its abuse and that potential long-term effects still largely lack scientific data. Disturbances of the epigenome have generally been hypothesized as the molecular machinery underlying the persistent, often tissue-specific transcriptional and behavioral effects of cannabinoids that have been observed within one’s lifetime and even into the subsequent generation. Here, we provide an overview [...]

Changes in global and thalamic brain connectivity in LSD-induced altered states of consciousness are attributable to the 5- HT2A receptor, Katrin H. Preller, Franz X. Vollenweider et al., 2018

Changes in global and thalamic brain connectivity in LSD-induced altered states of consciousness are attributable to the 5- HT2A receptor Katrin H. Preller, Joshua B. Burt, Jie Lisa Ji, Charles Schleifer, Brendan D. Adkinson, Philipp Stampfli, Erich Seifritz, Grega Repovs, John H. Krystal, John D. Murray, Franz X. Vollenweider, Alan Anticevic eLife, 2018, 7, e35082. DOI: https://doi.org/10.7554/eLife.35082.001 Abstract Background : Lysergic acid diethylamide (LSD) has agonist activity at various serotonin (5-HT) and dopamine receptors. Despite the therapeutic and scientific interest in LSD, specific receptor  contributions to its neurobiological effects remain unknown. Methods : We therefore conducted a double-blind, randomized, counterbalanced, cross-over study (ClinicalTrials.gov, NCT02451072) during which [...]

Dynamical exploration of the repertoire of brain networks at rest is modulated by psilocybin, Louis-David Lord, David J. Nutt, Robin L. Carhart-Harris et al., 2019

Dynamical exploration of the repertoire of brain networks at rest is modulated by psilocybin Louis-David Lord, Paul Expert, Selen Atasoy, Leor Roseman, Kristina Rapuano, Renaud Lambiotte, David J. Nutt, Gustavo Deco, Robin L. Carhart-Harris, Morten L. Kringelbach, Joana Cabral, NeuroImage, 2019, 199, 127–142 https://doi.org/10.1016/j.neuroimage.2019.05.060 A B S T R A C T Growing evidence from the dynamical analysis of functional neuroimaging data suggests that brain function can be understood as the exploration of a repertoire of metastable connectivity patterns (‘functional brain networks’), which potentially underlie different mental processes. The present study characterizes how the brain's dynamical exploration of resting-state networks is rapidly modulated by intravenous [...]

Pilot study of the 5-HT2AR agonist psilocybin in the treatment of tobacco addiction, Matthew W. Johnson et al., 2014

Pilot study of the 5-HT2AR agonist psilocybin in the treatment of tobacco addiction Matthew W Johnson, Albert Garcia-Romeu, Mary P Cosimano and Roland R Griffiths Journal of Psychopharmacology, 2014, Vol. 28(11) 983–992 © The Author(s) 2014 Reprints and permissions: sagepub.co.uk/journalsPermissions.nav DOI: 10.1177/0269881114548296 Abstract Despite suggestive early findings on the therapeutic use of hallucinogens in the treatment of substance use disorders, rigorous follow-up has not been conducted. To determine the safety and feasibility of psilocybin as an adjunct to tobacco smoking cessation treatment we conducted an openlabel pilot study administering moderate (20 mg/70 kg) and high (30 mg/70 kg) doses of psilocybin within a structured 15-week smoking cessation treatment [...]

The Endocannabinoid System and its Modulation by Phytocannabinoids, Vincenzo Di Marzo & Fabiana Piscitelli, 2015

The Endocannabinoid System and its Modulation by Phytocannabinoids Vincenzo Di Marzo & Fabiana Piscitelli Neurotherapeutics, 2015, 12, 692–698 DOI 10.1007/s13311-015-0374-6 Abstract : The endocannabinoid system is currently defined as the ensemble of the two 7-transmembrane-domain and G protein-coupled receptors for Δ9-tetrahydrocannabinol (but not for most other plant cannabinoids or phytocannabinoids)—cannabinoid receptor type-1 (CB1R) and cannabinoid receptor type-2 (CB2R); their two most studied endogenous ligands, the “endocannabinoids” N-arachidonoyl-ethanolamine (anandamide) and 2-arachidonoylglycerol (2-AG); and the enzymes responsible for endocannabinoid metabolism. However, anandamide and 2-AG, and also the phytocannabinoids, have more molecular targets than just CB1R and CB2R. Furthermore, the endocannabinoids, like most other lipid mediators, have more [...]

Modern History of Medical Cannabis : From Widespread Use to Prohibitionism and Back, Simona Pisanti and Maurizio Bifulco, 2017

Modern History of Medical Cannabis : From Widespread Use to Prohibitionism and Back Simona Pisanti and Maurizio Bifulco Trends in Pharmacological Sciences, Cell Press,  2017, 38, 3, 195-198. doi: 10.1016/j.tips.2016.12.002.   Over the history of pharmacology there are numerous examples of drugs being widely distributed, almost ‘trendy’, prescribed by physicians in a certain period as a sort of panacea, and then neglected, forgotten, or even forbidden as they become considered dangerous in the light of clinical observations. One of these drugs is Cannabis, which was very popular in the 19th century until disappearing from the official Pharmacopoeia at the beginning of the 20th century and [...]

Introduction to Recent Advances in Cannabinoid Research, Robert B. Laprairie and Will Costain, 2016

Introduction to Recent Advances in Cannabinoid Research Robert B. Laprairie and Will Costain © 2016 The Author(s). Licensee InTechOpen. This chapter is distributed under the terms of the Creative Commons; Attribution License (http://creativecommons.org/licenses/by/3.0), Abstract On October 17, 2018, Canada became the first G20 nation to legalize the use of Cannabis sativa for both medicinal and recreational purposes. This change in legislation and end of prohibition are indicative of a larger global movement to understand Cannabis—and the bioactive chemicals present within Cannabis known as the cannabinoids—for its potential biomedical uses, harms, and economic values. Currently, interest in Cannabis and cannabinoid research is surging as the many [...]
