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 [...]

Carney, and Benjamin D. Philpot Journal of Clinical Investigation, 2019 Sep 10, pii: 130419. doi : 10.1172/JCI130419 PMID : 31503547 Abstract Angelman syndrome (AS) is a neurodevelopmental disorder characterized by intellectual disability, lack of speech, ataxia, EEG abnormalities, and epilepsy.

Walker, Mahmoud A. ElSohly, Bill J. Gurley and Igor Koturbash Molecules, 2019, 24, 1694 doi : 10.3390/molecules24091694 Abstract : The goal of this study was to investigate Cannabidiol (CBD) hepatotoxicity in 8-week-old male B6C3F1 mice. Animals were gavaged with either 0, 246, 738, or 2460 mg/kg of CBD (acute toxicity, 24 h) or with daily doses of 0, 61.5, 184.5, or 615 mg/kg for 10 days (sub-acute toxicity). These doses were the allometrically scaled mouse equivalent doses (MED) [...]

Bertrand Lebeau Leibovici Médecin addictologue Membre fondateur du GRECC Juin 2019 Agnès Buzin réussira-t-elle là où Bernard Kouchner puis Marisole Touraine ont échoué ? En queue de peloton européen sur la question de l’accès au cannabis à usage thérapeutique, la France, reconnait l’actuelle ministre de la Santé, a pris du « retard ». Pour le rattraper, elle a demandé à l’Agence Nationale de Sécurité du Médicament (ANSM) de créer un Comité Scientifique Spécialisé Temporaire (CSST) présidé par le professeur Nicolas Authier, qui dirige aussi la Commission des Stupéfiants et Psychotropes, dans le cadre de l’ANSM.

Patricia Schonhofen, Ivi Juliana Bristot, José Alexandre Crippa, Jaime Eduardo Cecilio Hallak, Antonio Waldo Zuardi, Richard B. Parsons, Fabio Klamt CNS Drugs, 2018, 32 (Suppl 1), 1-16 https///doi.org/10.1007/s40263-018-0550-4 Abstract : The endocannabinoid retrograde signaling pathway is widely expressed in the central nervous system, where it plays major roles in regulating synaptic plasticity (excitatory and inhibitory) through long-term potentiation and long-term depression. The endocannabinoid system (ECS) components-cannabinoid receptors, endocannabinoids and synthesis/degradation enzymes-are expressed and are functional from early developmental stages and throughout adolescent cortical development, regulating progenitor cell fate, neural [...]
