Lutte contre les stupéfiants : la stigmatisation doit cesser ! 10/09/2020

Lutte contre les stupéfiants : la stigmatisation doit cesser !   Les récentes prises de parole du Ministre de l’Intérieur quant à sa stratégie de lutte contre les usages de stupéfiants révèlent un mépris envers les usagers-ères et une incohérence dans les politiques menées. Nous, Nous, associations travaillant auprès des usagers, magistrats, avocats, policiers, usagers, ne pouvons tolérer ces propos et les directions prises qui stigmatisent et précarisent encore davantage des populations déjà vulnérabilisées par 50 ans de politiques répressives.   Afin d’assurer le service après-vente de la généralisation de l’Amende Forfaitaire Délictuelle, le ministre de l’intérieur multiplie les prises de parole, bombant le [...]

Neural Mechanisms for the Cannabinoid Modulation of Cognition and Affect in Man : A Critical Review of Neuroimaging Studies, Sagnik Bhattacharyya et al., 2012,

Neural Mechanisms for the Cannabinoid Modulation of Cognition and Affect in Man : A Critical Review of Neuroimaging Studies Sagnik Bhattacharyya, Zerrin Atakan, Rocio Martin-Santos, Jose A. Crippa and Philip K. McGuire Current Pharmaceutical Design, 2012, 18, 5045-5054   Abstract Pharmacological challenge in conjunction with neuroimaging techniques has been employed for over two decades now to understand the neural basis of the cognitive, emotional and symptomatic effects of the main ingredients of cannabis, the most widely used illicit drug in the world. This selective critical review focuses on the human neuroimaging studies investigating the effects of delta-9-tetrahydrocannabinol (THC) and cannabidiol (CBD), the two main cannabinoids [...]

Cannabidiol for the treatment of cannabis use disorder : a phase 2a, double-blind, placebo-controlled, randomised, adaptive Bayesian trial, Tom P. Freeman et al., 2020

Cannabidiol for the treatment of cannabis use disorder : a phase 2a, double-blind, placebo-controlled, randomised, adaptive Bayesian trial Tom P Freeman, Chandni Hindocha, Gianluca Baio, Natacha D C Shaban, Emily M Thomas, Danica Astbury, Abigail M Freeman, Rachel Lees, Sam Craft, Paul D Morrison, Michael A P Bloomfield, Dominic O'Ryan, Jane Kinghorn, Celia J A Morgan, Ali Mofeez, H Valerie Curran The Lancet Psychiatry, 2020, doi : 10.1016/S2215-0366(20)30290-X  Abstract Background : A substantial and unmet clinical need exists for pharmacological treatment of cannabis use disorders. Cannabidiol could offer a novel treatment, but it is unclear which doses might be efficacious or safe. Therefore, we aimed to identify efficacious doses and eliminate inefficacious doses in a phase 2a trial using [...]

Cytotoxic Effects of Cannabinoids on Human HT-29 Colorectal Adenocarcinoma Cells: Different Mechanisms of THC, CBD, and CB83, Daniela Cerretani et al., 2020

Cytotoxic Effects of Cannabinoids on Human HT-29 Colorectal Adenocarcinoma Cells : Different Mechanisms of THC, CBD, and CB83 Daniela Cerretani, Giulia Collodel, Antonella Brizzi, Anna Ida Fiaschi, Andrea Menchiari, Elena Moretti, Laura Moltoni, Lucia Micheli International Journal of Molecular Sciences, 2020, 21, 5533 Doi : 10.3390/ijms21155533   Abstract In this study, we investigated the effects of exposition to IC50 dose for 24 h of a new synthetic cannabinoid (CB83) and of phytocannabinoids Δ9-tetrahydrocannabinol (THC) and cannabidiol (CBD) on HT-29 colorectal carcinoma cells. Cell viability and proliferative activity evaluated using the MTT, lactate dehydrogenase (LDH), and CyQUANT assays showed that cell viability was significantly affected when CB83, THC, and CBD [...]

Cannabidiol (CBD) Is a Novel Inhibitor for Exosome and Microvesicle (EMV) Release in Cancer, Uchini S. Kosgodage et al., 2018

Cannabidiol (CBD) Is a Novel Inhibitor for Exosome and Microvesicle (EMV) Release in Cancer Uchini S. Kosgodage, Rhys Mould, Aine B. Henley, Alistair V. Nunn, Geoffrey W. Guy, E. L. Thomas, Jameel M. Inal, Jimmy D. Bell and Sigrun Lange Frontiers in Pharmacology, 2018, Volume 9, Article 889 doi : 10.3389/fphar.2018.00889   Exosomes and microvesicles (EMV) are lipid bilayer-enclosed structures, released by cells and involved in intercellular communication through transfer of proteins and genetic material. EMV release is also associated with various pathologies, including cancer, where increased EMV release is amongst other associated with chemo-resistance and active transfer of pro-oncogenic factors. Recent studies show that [...]

The Effects of Cannabidiol and Prognostic Role of TRPV2 in Human Endometrial Cancer, Oliviero Marinelli et al., 2020,

The Effects of Cannabidiol and Prognostic Role of TRPV2 in Human Endometrial Cancer Oliviero Marinelli, Maria Beatrice Morelli, Daniela Annibali, Cristina Aguzzi, Laura Zeppa, Sandra Tuyaerts, Consuelo Amantini, Frédéric Amant, Benedetta Ferretti, Federica Maggi, Giorgio Santoni, Massimo Nabissi International Journal of Molecular Sciences, 2020, 21, 5409 doi : 10.3390/ijms21155409   Abstract : Several studies support, both in vitro and in vivo, the anti-cancer effects of cannabidiol (CBD), a transient receptor potential vanilloid 2 (TRPV2) ligand. TRPV2, often dysregulated in tumors, is associated with altered cell proliferation and aggressiveness. Endometrial cancer (EC) is historically divided in type I endometrioid EC and type II non-endometrioid EC, associated with [...]

Medicinal use of cannabis based products and cannabinoids, Tom P Freeman et al., 2019

Medicinal use of cannabis based products and cannabinoids Tom P. Freeman, Chandni Hindocha, Sebastian F. Green, Michael A. P. Bloomfield British Medical Journal, 2019, 365, l1141 doi : 10.1136/bmj.l1141   What you need to know • Cannabis based products for medicinal use contain cannabinoids derived from the cannabis plant, including Δ9-tetrahydrocannabinol (THC), cannabidiol (CBD), or a combination of THC and CBD. Synthetic cannabinoids for medicinal use typically mimic the effects of specific cannabinoids such as THC • THC is the constituent of cannabis that causes the “high,” whereas CBD is not intoxicating at typical doses. THC and CBD have contrasting mechanisms of action and therapeutic indications; THC [...]

5-HT1A receptors are involved in the cannabidiol-induced attenuation of behavioural and cardiovascular responses to acute restraint stress in rats, Leonardo B.M. Resstel et al., 2009

5-HT1A receptors are involved in the cannabidiol-induced attenuation of behavioural and cardiovascular responses to acute restraint stress in rats Leonardo B.M. Resstel, Rodrigo F. Tavares, Sabrina F.S. Lisboa, Sâmia R.L. Joca, Fernando M.A. Corrêa and Francisco S. Guimarães British Journal of Pharmacology, 2009, 156, 181–188; doi : 10.1111/j.1476-5381.2008.00046.x Background and purpose : Cannabidiol (CBD) is a non-psychotomimetic compound from Cannabis sativa which induces anxiolytic- and antipsychotic-like effects in rodents. These effects could be mediated by facilitation of the endocannabinoid system or by the activation of 5-HT1A receptors. As either of these mechanisms could promote adaptation to inescapable stress, the aim of the present work [...]
