McIntyre Expert Opinion on Drug Safety, 2018, 17:1, 51-54. Doi : 10.1080/14740338.2017.1397128 ABSTRACT Introduction : To determine, via narrative, non-systematic review of pre-clinical and clinical studies, whether the effect of cannabis on hepatic biotransformation pathways would be predicted to result in clinically significant drug-drug interactions (DDIs) with commonly prescribed psychotropic agents. Areas covered: A non-systematic literature search was conducted using the following [...]
Lire la suiteEvaluation of the effects of CBD hemp extract on opioid use and quality of life indicators in chronic pain patients : a prospective cohort study Alex Capano, Richard Weaver & Elisa Burkman Postgraduate Medicine, 2019, © 2019 The Author(s). Published by Informa UK Limited, trading as Taylor & Francis Group. Doi : 10.1080/00325481.2019.1685298 ABSTRACT Context : Chronic pain is highly prevalent in most of the industrialized nations around the world. Despite the documented adverse effects, opioids are widely used for pain management. Cannabinoids, and specifically Cannabidiol, is proposed as an opioid alternative, having comparable efficacy with better safety profile. Objectives : We aim to investigate the impact [...]

Broyd, Yann Chye, Chao Suo, Mark Schira, Peter Galettis, Jennifer H. Martin, Murat Yücel and Nadia Solowij Cannabis and Cannabinoid Research, 2018, 3, 1, 94-107. Doi : 10.1089/can.2017.0047 Abstract Introduction : Chronic cannabis use is associated with neuroanatomical alterations in the hippocampus. While adverse impacts of cannabis use are generally attributed to D9 tetrahydro-cannabinol, emerging naturalistic evidence suggests cannabidiol (CBD) is neuroprotective and may ameliorate brain harms associated with cannabis use, including protection from hippocampal volume loss. This study examined whether prolonged administration of CBD to regular cannabis users [...]
Lire la suiteCannabidiol Counteracts the Psychotropic Side-Effects of Δ-9-Tetrahydrocannabinol in the Ventral Hippocampus Through Bi-Directional Control of ERK1-2 Phosphorylation Roger Hudson, Justine Renard, Christopher Norris, Walter J. Rushlow and Steven R. Laviolette The Journal of Neuroscience, 2019 https://doi.org/10.1523/JNEUROSCI.0708-19.2019 Abstract Evidence suggests that the phytocannabinoids Δ-9-tetrahydrocannabinol (THC) and cannabidiol (CBD) differentially regulate salience attribution and psychiatric risk. The ventral hippocampus (vHipp) relays emotional salience via control of dopamine (DA) neuronal activity states, which are dysregulated in psychosis and schizophrenia. Using in-vivo electrophysiology in male Sprague Dawley rats, we demonstrate that intra-vHipp THC strongly increases ventral tegmental area (VTA) DA neuronal frequency and bursting rates, decreases GABA frequency, and [...]
Lire la suiteCBD Isolates Vs. Full-Spectrum CBD Martin A. Lee On February 22, 2015 https://www.projectcbd.org/science/cbd-isolates-vs-full-spectrum-cbd A groundbreaking study has documented the superior therapeutic properties of whole plant CBD-rich cannabis extract as compared to single-molecule CBD. A groundbreaking study from Israel has documented the superior therapeutic properties of whole plant CBD-rich cannabis extract as compared to single-molecule cannabidiol (CBD). Published in the journal Pharmacology & Pharmacy (Feb. 2015), the article directly challenges one of the sacred cows of Big Pharma and the medical-industrial complex—the notion that “crude” botanical preparations are inherently low grade and less effective than pure, single-molecule compounds. Entitled “Overcoming the Bell-Shaped Dose-Response of Cannabidiol by Using Cannabis [...]

Stith Medicines, 2018, 5, 86, 1-11. doi : 10.3390/medicines5030086 Abstract Background : Approximately 0.5% of the population is diagnosed with some form of schizophrenia, under the prevailing view that the pathology is best treated using pharmaceutical medications that act on monoamine receptors. Methods : We briefly review evidence on the impact of environmental forces, particularly the effect of autoimmune activity, in the expression of schizophrenic profiles and the role of Cannabis therapy for regulating immunological functioning. Results : A review of the literature shows that phytocannabinoid consumption may [...]
Lire la suiteTherapeutic potential of cannabinoid medicines Philip J. Robson Drug and Testing Analysis, 2014 Doi : 10.1002/dta.1529 Cannabis was extensively used as amedicine throughout the developed world in the nineteenth century but went into decline early in the twentieth century ahead of its emergence as the most widely used illicit recreational drug later that century. Recent advances in cannabinoid pharmacology alongside the discovery of the endocannabinoid system (ECS) have re-ignited interest in cannabis-based medicines. The ECS has emerged as an important physiological system and plausible target for new medicines. Its receptors and endogenous ligands play a vital modulatory role in diverse functions including immune response, [...]

Renata Androvicova, Jiri Horacek, Tibor Stark, Filippo Drago, Vincenzo Micale Pharmacological Research, 2017, 115, 200–208 http://dx.doi.org/10.1016/j.phrs.2016.11.021 a b s t r a c t The endocannabinoid system (ECS), which is composed of the cannabinoid receptors types 1 and 2 (CB1 and CB2) for marijuana’s psychoactive ingredient 9-tetrahydrocannabinol (9-THC), the endogenous ligands (AEA and 2-AG) and the enzymatic systems involved in their biosynthesis and degradation, recently emerged as important modulator of emotional and non-emotional behaviors. For centuries, in addition to its recreational actions, several contradictory claims regarding the effects of Cannabis use in sexual functioning and behavior [...]
Lire la suiteTherapeutic potential of cannabinoids in schizophrenia, KUCEROVA J., TABIOVA K., DRAGO F., MICALE V. Recent Patents on CNS Drug Discovery, 2014, 9, (1), 13-25. Doi : 10.2174/1574889809666140307115532 Abstract Increasing evidence suggests a close relationship between the endocannabinoid system and schizophrenia. The endocannabinoid system comprises of two G protein-coupled receptors (the cannabinoid receptors 1 and 2 [CB1 and CB2] for marijuana's psychoactive principle Δ(9)-tetrahydro-cannabinol), their endogenous small lipid ligands (namely anandamide [AEA] and 2-arachidonoyl-glycerol [2-AG], also known as endocannabinoids), and proteins for endocannabinoid biosynthesis and degradation. It has been suggested to be a pro-homeostatic and pleiotropic signalling system activated in a time- and tissue-specific manner during [...]
