Cannabis‐based products for pediatric epilepsy : A systematic review Jesse Elliott, Deirdre DeJean, Tammy Clifford, Doug Coyle, Beth K. Potter, Becky Skidmore, Christine Alexander, Alexander E. Repetski, Vijay Shukla, Bláthnaid McCoy, George A. Wells, Epilepsia, 2018, 1-14. DOI: 10.1111/epi.14608 Summary Objective : To assess the benefits and harms of cannabis‐based products for pediatric epilepsy. Methods : We identified in this living systematic review randomized controlled trials (RCTs) and nonrandomized studies (NRSs) involving children with epilepsy treated with cannabis‐based products. We searched MEDLINE, Embase, PsycINFO, Cochrane Library, and gray literature (April 25, 2018). The primary outcome was seizure freedom; secondary outcomes were seizure frequency (total, ≥50% reduction), quality of life, sleep, status epilepticus, death, gastrointestinal adverse [...]

Preuss und Michael Soyka January 2019 DOI: 10.1016/B978-3-437-23021-9.00009-6 Kernaussagen ● Die Cannabispflanze, welche die Menschheit seit Jahrtausenden begleitet, wird vi elfältig genutzt: ○ als Lieferant für Fasern zur Herstellung von Tüchern, Schnüren, Seilen und Papier, ○ als Nahrungsmittel (Samenkörner und Öl), ○ als Medizin für Mensch und Tier sowie als Genussmittel. ● Im 19. Jh. hielt Cannabis Einzug in die moderne westliche Medizin und wurde auch als „Freizeitdroge“ genutzt. Aus dieser Zeit stammen detaillierte phänomenologische Bes chreibungen der Effekte. Noch blieb aber der Wirkmechanismus völlig unklar. ● Die erste Hälfte des 20. Jh. ist das „dunkle Zeitalter“ des Cannabis, in dem das Fors chungsinteresse erlahmte. [...]

Background : Anxiety reactions and panic attacks are the acute symptoms most frequently associated with cannabis use. Understanding the relationship between cannabis and anxiety may clarify the mechanism of action of cannabis and the pathophysiology of anxiety. Aims of the present study were to review the nature of the relationship between cannabis use and anxiety, as well as the possible clinical, diagnostic and causal implications. Method : Systematic review of the [...]

From a theoretical perspective, adolescence represents a period of both risk and resilience to the harms of cannabis use and cannabis use disorders. The aim of this systematic review is to provide a critical examination of the moderating role of age on the relationship between [...]
Lire la suiteVariétés de Cannabis: Par Docteur Ethan Russo http://www.cannabis-med.org/index.php?tpl=faq&red=faqlist&id=172&lng=fr Les consommateurs de cannabis ont souvent indiqué que les différentes variétés de cannabis produisent des effets variables, que se soit concernant les effets psychoactifs ou les bénéfices thérapeutiques. Les variétés sont généralement désignées comme étant soit Sativa, soit Indica, soit hybrides. Or, ces noms, d’un point de vue commercial, prêtent à confusion. Pour cette raison, la communauté scientifique s’est concentrée sur le Tétrahydrocannabinol (THC) qu’elle considérait comme la principale variable et la seule d’importance. En parallèle, jusqu’à très récemment, les croisements sélectifs des variétés de cannabis, destiné à l’usage récréatif ou à l’usage thérapeutique, [...]

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 [...]

Taffe Committee on the Neurobiology of Addictive Disorders, The Scripps Research Institute, La Jolla, CA, USA British Journal of Pharmacology, 2013, 170, 1365–1373 BACKGROUND AND PURPOSE Recent human studies suggest that recreational cannabis strains that are relatively high in cannabidiol (CBD) content produce less cognitive impairment than do strains with negligible CBD and similar D9tetrahydrocannabinol (THC) content. Self-selection in such studies means it is impossible to rule out additional variables which may determine both cannabis strain selection and basal cognitive performance level. Controlled laboratory studies can [...]

DOI : 10.1523/JNEUROSCI.2946-14.2015 Abstract : Recent research has suggested that marijuana use is associated with volumetric and shape differences in subcortical structures, including the nucleus accumbens and amygdala, in a dose-dependent fashion. Replication of such results in well controlled [...]

Using a web-based recruitment and data collection procedure, an online sample of 524 frequent marijuana consumers were administered a modified version of the Passion Scale (Marijuana-Harmonious and Obsessive Passion Scale; M-HOPS) and other questionnaires. Results from a canonical correlation analysis indicated that obsessive passion scores were significantly positively associated with past 30-day consumption, [...]
