Cannabis : From Cultivar to Chemovar II—A Metabolomics. Approach to Cannabis Classification Arno Hazekamp, Katerina Tejkalova, and Stelios Papadimitriou Cannabis and Cannabinoid Research, 2016, Volume 1, (1) Doi : 10.1089/can.2016.0017 Abstract Introduction : There is a large disparity between the ‘‘cultural’’ language used by patients using cannabis for selfmedication and the ‘‘chemical’’ language applied by scientists to get a deeper understanding of cannabis effects in laboratory and clinical studies. The distinction between Sativa and Indica types of cannabis, and the different biological effects associated with them, is a major example of this. Despite the widespread use of cannabis by selfmedicating patients, scientific studies are yet [...]
Lire la suiteThat which we call Indica, by any other name would smell as sweet. An essay on the history of the term Indica and the taxonomical conflict between the monotypic and polytypic views of Cannabis Jacob L. Erkelens, Arno Hazekamp Bedrocan BV, The Netherlands Cannabinoids, 2014, 9, (1), 9-15. What’s in a name ? An interesting feature of the worldwide subculture devoted to cannabis is the endless number of names given to its preparations (marijuana, pot, weed, kiff, bhang..). On top of that, there is a continuously grow-ing list of names used to describe different varieties and strains of the cannabis plant. As a result of [...]

Nature-based settings can have inherently psychologically soothing properties which may complement all stages of psychedelic therapy (mainly [...]

Nutt, Amanda Feilding, Mendel Kaelen, Morten L. Kringelbach, Adam B. Barretti, Anil K. Seth, Suresh Muthukumaraswamy, Daniel Bor, and Robin L. Carhart-Harris bioRxiv preprint, 2020 doi : 10.1101/2020.11.01.356071 Abstract Recent findings have shown that psychedelics reliably enhance brain entropy (understood as neural signal diversity), and this effect has been associated with both acute and long-term psychological outcomes such as personality changes. These findings are particularly intriguing given that a decrease of brain entropy is a robust indicator of loss of consciousness (e.g. from wakefulness to [...]

Introduction L’association Principes Actifs milite pour la reconnaissance légale de l’usage thérapeutique du cannabis en France depuis sa création en 2009. Nous fournissons conseils et informations aux personnes atteintes d’affections diverses qui nous contactent. En 2014, nous avons mis en place des « ateliers de réduction des risques cannabis » à destination des structures d’addictologie, des professionnels de santé et des associations de patients, afin de présenter l’usage thérapeutique dans toutes ses spécificités. L’association participe depuis fin 2019 au comité de pilotage instauré par [...]
Lire la suiteSynthetic Pot : Not Your Grandfather’s Marijuana Benjamin M. Ford, Sherrica Tai, William E. Fantegrossi, and Paul L. Prather Trends in Pharmacological Sciences, 2017, 38, (3), 257–276. doi : 10.1016/j.tips.2016.12.003 Abstract In the early 2000’s in Europe and shortly thereafter in the USA, it was reported that “legal” forms of marijuana were being sold under the name K2 and/or Spice. Active ingredients in K2/Spice products were determined to be synthetic cannabinoids (SCBs), producing psychotropic actions via CB1 cannabinoid receptors, similar to those of Δ9-THC, the primary active constituent in marijuana. Often abused by adolescents and military personnel to elude detection in drug tests due to [...]
Lire la suiteSynthetic and Non-synthetic Cannabinoid Drugs and Their Adverse Effects-A Review From Public Health Prospective Koby Cohen and Aviv M. Weinstein Frontiers in Public Health, 2018, Volume 6 | Article 162 doi : 10.3389/fpubh.2018.00162 There is a growing use of novel psychoactive substances containing synthetic cannabinoids. Synthetic cannabinoid products have effects similar to those of natural cannabis, yet, these drugs are more potent and dangerous, and have been associated with dangerous adverse effects. Here, we review current literature on the epidemiology, acute, and chronic effects of synthetic and natural cannabinoid-based drugs. Synthetic drugs contain a mixture of psychoactive compounds that mostly bind cannabinoid receptors with [...]
Lire la suiteSynthetic cannabinoids and potential cardiac arrhythmia risk : an important message for drug users Jules C. Hancox, Nicola J. Kalk and Graeme Henderson Therapeutic Advances in Drug Safety, 2020, 11, 1-4. Doi : 10.1177/2042098620913416 Δ9-Tetrahydrocannabinol, the psychoactive ingredient in cannabis, and synthetic cannabinoid receptor agonists (SCRAs) activate the CB1 receptor to produce their profound behavioural effects and are widely used as recreational drugs. There is growing evidence that SCRAs, commonly known by the street name Spice or K2 (though there are many others, see: http://www.emcdda.europa.eu/publications/drug-profiles/synthetic-cannabinoids) can produce detrimental cardiovascular effects.(1) Commonly observed cardiotoxic effects of SCRAs include tachycardia, chest pain and hypertension.(1) However, bradycardia and [...]
Lire la suiteCannabinoïdes synthétiques https://www.psychoactif.org/psychowiki/index.php?title=Cannabino%C3%AFdes_synth%C3%A9tiques Les cannabinoïdes synthétiques sont des molécules de synthèse qui agissent d'une façon proche de celle des cannabinoïdes végétaux, naturellement présents dans le cannabis (comme le THC)[1]. Ce sont principalement des agonistes des récepteurs cannabinoïdes. La plupart ont été développés à des fins thérapeutiques (analgésie), d’autres ont été synthétisés dans le but de créer des alternatives légales au cannabis. Les cannabinoïdes synthètiques sont la classe la plus importante des nouveaux produits de synthèse. Sur les 73 nouvelles substances de synthèses reportées par le EMCDDA en 2012, 30 étaient des cannabinoïdes de synthèse. De 2008 à mai 2013, 84 cannabinoïdes de synthèse ont [...]
