Unique treatment potential of cannabidiol for the prevention of relapse to drug use: preclinical proof of principle, Gustavo Gonzalez-Cuevas et al., 2018

Unique treatment potential of cannabidiol for the prevention of relapse to drug use: preclinical proof of principle Gustavo Gonzalez-Cuevas, Remi Martin-Fardon, Tony M. Kerr, David G. Stouffer, Loren H. Parsons, Dana C. Hammell, Stan L. Banks, Audra L. Stinchcomb and Friedbert Weiss Neuropsychopharmacology, 2018, 43, 2036–2045. Doi : 10.1038/s41386-018-0050-8   Cannabidiol (CBD), the major non-psychoactive constituent of Cannabis sativa, has received attention for therapeutic potential in treating neurologic and psychiatric disorders. Recently, CBD has also been explored for potential in treating drug addiction. Substance use disorders are chronically relapsing conditions and relapse risk persists for multiple reasons including craving induced by drug contexts, susceptibility to [...]

Down-Regulation of Cannabinoid Type 1 (CB1) Receptor and its Downstream Signaling Pathways in Metastatic Colorectal Cancer, Valeria Tutino et al., 2019

Down-Regulation of Cannabinoid Type 1 (CB1) Receptor and its Downstream Signaling Pathways in Metastatic Colorectal Cancer Valeria Tutino, Maria Gabriella Caruso, Valentina De Nunzio, Dionigi Lorusso, Nicola Veronese, Isabella Gigante, Maria Notarnicola and Gianluigi Giannelli Cancers, 2019, 11, 708, 1-14. doi :10.3390/cancers11050708   Abstract : Changes in the regulation of endocannabinoid production, together with an altered expression of their receptors are hallmarks of cancer, including colorectal cancer (CRC). Although several studies have been conducted to understand the biological role of the CB1 receptor in cancer, little is known about its involvement in the metastatic process of CRC. The aim of this study was to investigate the [...]

Nonlinear Disposition and Metabolic Interactions of Cannabidiol Through CYP3A Inhibition In Vivo in Rats, Michiru Nagao et al., 2020

Nonlinear Disposition and Metabolic Interactions of Cannabidiol Through CYP3A Inhibition In Vivo in Rats Michiru Nagao, Yukako Nakano, Masataka Tajima, Erika Sugiyama, Vilasinee Hirunpanich Sato, Makoto Inada, and Hitoshi Sato Cannabis and Cannabinoid Research, 2020, Volume X, Number X, 1-8. DOI: 10.1089/can.2019.0098   Abstract Introduction : Cannabidiol (CBD) is known to affect the pharmacokinetics of other drugs through metabolic inhibition of CYP2C19 and CYP3A4. However, there is a lack of in vivo evidence for such drug interactions. Therefore, we investigated the saturability of CBD metabolism and CBD-drug interactions through inhibition of CYP3A in vivo. Materials and Methods : A nanoemulsion formulation of CBD (CBD-NE) was orally administered to [...]

Bibliographie : Interactions et antagonisme THC – CBD, Docteur Christian SUEUR, GRECC, mars 2020.

Bibliographie : Interactions et antagonisme THC - CBD   Docteur Christian SUEUR, GRECC, mars 2020.   Les interactions entre le THC et le CBD sur le système endocannabinoide, quant aux effets psychotomimetic (production de "symptomes psychotiques") sont opposés : là où le THC produit préférentiellement de l'anxiété, et des effets "psychotisants", le CBD est plutôt anxiolytique et "antipsychotique". Ces deux phytocannabinoïdes sont "antagonistes", et contribuent, parmi d'autres inter-relations entre les phytocannabinoïdes, les terpènes et les flavonoïdes composant le cannabis, aux "effets d'entourage" fondamentaux, tout autant quant à la production "d'effets indésirables" et de risques pour la santé mentale du consommateur, que dans le cadre de [...]

Marijuana Use Continues to Grow in Older Adults, Pauline Anderson, Medscape, 26 February 2020

Marijuana Use Continues to Grow in Older Adults Pauline Anderson Medscape, February 26, 2020 https://www.medscape.com/viewarticle/925762?nlid=134178_2052&src=WNL_mdplsnews_200228_mscpedit_psyc&uac=292598PZ&spon=12&impID=2294726&faf=1   Cannabis use in older Americans is growing. New research shows that over a 4-year period use of the drug in individuals age 65 and older increased by 75%. Joseph J. Palamar, PhD, MPH This population is especially vulnerable to potential adverse effects from cannabis and so this population needs to understand the potential risks associated with marijuana use, study investigator Joseph J. Palamar, PhD, MPH, associate professor, Department of Population Health, New York University (NYU) Langone Medical Center, New York City, told Medscape Medical News. The findings, he added, indicate a need for more [...]

Acute and chronic effects of cannabinoids on effort-related decision-making and reward learning: an evaluation of the cannabis ‘amotivational’ hypotheses Will Lawn, Tom P. Freeman, Rebecca A. Pope, Alyssa Joye, Lisa Harvey, Chandni Hindocha, Claire Mokrysz, Abigail Moss, Matthew B. Wall, Michael A.P. Bloomfield, Ravi K. Das, Celia J.A. Morgan, David J. Nutt, H. Valerie Curran Psychopharmacology, 2016, 233, 3537–3552 Doi : 10.1007/s00213-016-4383-x   Abstract Rationale : Anecdotally, both acute and chronic cannabis use have been associated with apathy, amotivation, and other reward processing deficits. To date, empirical support for these effects is limited, and no previous studies have assessed both acute effects of Δ-9-tetrahydrocannabinol (THC) and [...]
