Cannabidiol as a potential treatment for psychosis C.D. Schubart, I.E.C. Sommer, P. Fusar-Poli, L. de Witte, R.S. Kahn, M.P.M. Boks European Neuropsychopharmacology, 2014, 24 ,(1), 51–64. http://dx.doi.org/10.1016/j.euroneuro.2013.11.002 Abstract Although cannabis use is associated with an increased risk of developing psychosis, the cannabis constituent cannabidiol (CBD) may have antipsychotic properties. This review concisely describes the role of the endocannabinoid system in the development of psychosis and provides an overview of currently available animal, human experimental, imaging, epidemiological and clinical studies that investigated the antipsychotic properties of CBD. In this targeted literature review we performed a search for English articles using Medline and EMBASE. Studies were selected if [...]

Doi : 10.3928/02793695-20190813-01 ABSTRACT The increasing public acceptance of cannabis and the proliferation of cannabis products in the market-place has coincided with more patients using the drug as a substitute for psychiatric medications or as an adjunctive treatment modality for psychiatric conditions, despite limited evidence of efficacy. With a goal of furthering harm-reduction eff orts in psychiatric nursing, the current article reviews the fundamentals of the endocannabinoid system in humans and the exogenous phytocannabinoids that act on this regulatory [...]

Molecular Basis of Neuropsychiatric Disorders : from Bench to Bedside Sonja ELSAID, Stefan KLOIBER, Bernard Le FOLL Progress in Molecular Biology and Translational Science, 2019, 167, 25-75. doi : 10.1016/bs.pmbts.2019.06.005. Cannabis sativa (cannabis) is on of the oldest plants cultivated by men. Cannabidiol (CBD) is the major non-psychomimetic compound derived from cannabis. It has been proposed to have a therapeutic potential over a wide range of neuropsychiatric disorders. In this narrative review, we have summarized a selected number of pre-clinical and clinical studies, examining the effects of CBD in neuropsychiatric [...]
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 [...]
Lire la suiteA Systematic Review on the Pharmacokinetics of Cannabidiol in Humans Sophie A. Millar, Nicole L. Stone, Andrew S. Yates and Saoirse E. O’Sullivan Frontiers in Pharmacology, 26 November 2018 https://doi.org/10.3389/fphar.2018.01365 Background : Cannabidiol is being pursued as a therapeutic treatment for multiple conditions, usually by oral delivery. Animal studies suggest oral bioavailability is low, but literature in humans is not sufficient. The aim of this review was to collate published data in this area. Methods : A systematic search of PubMed and EMBASE (including MEDLINE) was conducted to retrieve all articles reporting pharmacokinetic data of CBD in humans. Results : Of 792 articles retireved, 24 included [...]

Cannabis has been suggested to stimulate appetite but research on this issue has yielded mixed results. The current study aimed to evaluate the effect of dosage-controlled cannabis capsules on CACS in advanced cancer patients. Methods : The cannabis capsules used in this study contained two fractions of oil-based compounds. The planned treatment was [...]
Lire la suiteTrends in Internet Searches for Cannabidiol (CBD) in the United States Eric C. Leas, Alicia L. Nobles, PhD, Theodore L. Caputi, Mark Dredze, DaveyM. Smith, JohnW. Ayers JAMA Network Open, 2019, 2, (10), e1913853. doi: 10.1001/jamanetworkopen.2019.13853 Introduction Cannabidiol (CBD) is widely promoted as a panacea. For example, the cannabis brand MedMen claims CBD treats acne, anxiety, opioid addiction, pain, and menstrual problems.1 However, the US Food and Drug Administration has only approved highly purified CBD (Epidiolex) for treating epilepsy. To our knowledge, there is currently no population-focused surveillance of public interest in CBD. Consequently, many question whether CBD should be prioritized by public health leaders [...]

Methods : We summarize the findings of English-language epidemiological studies reporting current (past-year) comorbidity and of controlled clinical trials of treatment in which the majority of participants had diagnosed CUD and a specific comorbid disorder. Results : There is substantial CUD comorbidity among community-dwelling adults with major psychiatric disorders: 4–6% for depression, 14% for bipolar disorder, 5% for anxiety disorder, and 16% for schizophrenia. Conversely, there is substantial psychiatric [...]

Abstract : Background : Several studies support the evidence that the endocannabinoid system and cannabimimetic drugs might have therapeutic potential in numerous pathologies. These pathologies range from neurological disorders, atherosclerosis, stroke, cancer to obesity/metabolic syndrome and others. Methods : In this paper we review the endocannabinoid system signaling and its alteration in neurodegenerative disorders like multiple sclerosis, Alzheimer’s disease, Parkinson’s disease and Huntington’s disease and discuss the main findings about the use [...]
