Le THCP : un nouveau cannabinoïde 33 fois plus fort que le THC Blog-cannabis.fr, 31 décembre 2019 https://www.blog-cannabis.fr/2019/12/31/thcp-nouveau-cannabinoide/ Un nouveau phytocannabinoïde isolé du Cannabis sativa L avec une activité cannabimimétique 30 fois supérieure au THC a été détecté dans le cannabis Le cannabinoïde végétal Tetrahydrocannabiphorol ( THCP ) le plus puissant au monde a récemment été découvert dans une étude en Italie. Il est presque identique dans sa structure au THC mais est 33 fois plus fort que lui, ainsi que du CBDP, le dérivé correspondant du CBD. La recherche pourrait permettre de développer de futures souches de THCP beaucoup plus puissantes. Jusqu’à présent, près de 150 [...]
Lire la suiteTHCp – Newly discovered and highly potent phytocannabinoid Source : cannabislifenetwork.com Publié le 1 Fév 2020 We have discovered so much about cannabis over the years, but it’s vast, intricate, pharmacological map is missing many major regions. CBD dominant varieties have exploded in demand, yet the cannabinoid is still only partially understood, and there is still CBG and CBN just around the market’s corner. Now, brand new forms of THC and CBD, THCp and CBDp, respectively, have been discovered; evidence that the map’s expanse is still beyond our grasp. Phytocannabinoids over synthetics Lately, stories of newly discovered cannabinoids are strewn with the accomplishments of a biochemist [...]

Lire la suite6 variétés de cannabis pleines de THCV Aurélien BERNARD Newsweed.fr, 30 janvier 2020 https://www.newsweed.fr/5-varietes-cannabis-thcv/ À mesure que les connaissances scientifiques sur le cannabis se développent, la composition chimique du cannabis et la manière dont il interagit avec le corps se dévoilent. Et si le CBD ou le THC sont largement étudiés, certains cannabinoïdes plus rares comme le THCV (tetrahydocannabivarine) intéressent de plus en plus les scientifiques. Au cours de la dernière décennie, des études sur des humains et des animaux ont identifié le potentiel du THCV pour réduire l’appétit chez les personnes qui luttent pour perdre du poids, réguler la glycémie chez les personnes atteintes [...]
Lire la suiteChanging landscape of cannabis : novel products, formulations, and methods of administration Tory R Spindle, Marcel O Bonn-Miller and Ryan Vandrey Current Opinion in Psychology, 2019, 30, 98–102 Doi : 10.1016/j.copsyc.2019.04.002 Abstract Laws regulating cannabis have changed radically in the U.S. and abroad. Historically, users smoked dried cannabis flowers that contained D9-tetrahydrocannabinol (THC), the primary psychoactive component of cannabis, as the principal product constituent. Coincident with cannabis legalization and increased interest in medicinal use of the plant, there is now an expansive retail cannabis marketplace with novel cannabis products, formulations, and methods of administration. In this review, we describe emergent cannabis product chemotypes (e.g. THC-dominant, [...]

Lynskey and Tom P. Freeman Psychological Medicine, 2019, 1–10. doi : 10.1017/S0033291719002460 Abstract Background. As new cannabis products and administration methods proliferate, patterns of use are becoming increasingly heterogeneous. However, few studies have explored different profiles of cannabis use and their association with problematic use. Methods. Latent class analysis (LCA) was used to identify subgroups of past-year cannabis users endorsing distinct patterns of use from a large international sample [...]

As additional jurisdictions legalize Cannabis products and the variety and complexity of these products surpass the classical dried plant material, appropriate methods for measuring the biologically active constituents is paramount to ensure [...]

Abstract The butyl homologues of Δ9-tetrahydrocannabinol, Δ9-tetrahydrocannabutol (Δ9-THCB), and cannabidiol, cannabidibutol (CBDB), were isolated from a medicinal Cannabis sativa variety (FM2) inflorescence. Appropriate spectroscopic and spectrometric characterization, including NMR, UV, IR, ECD, and HRMS, was carried out on both cannabinoids. The chemical structures and absolute configurations of the isolated cannabinoids were [...]

McPartland Cannabis and Cannabinoid Research, 2018, Volume 3.1, 203- Doi : 10.1089/can.2018.0039 Abstract New concepts are reviewed in Cannabis systematics, including phylogenetics and nomenclature. The family Cannabaceae now includes Cannabis, Humulus, and eight genera formerly in the Celtidaceae. Grouping Cannabis, Humulus, and Celtis actually goes back 250 years. Print fossil of the extinct genus Dorofeevia (=Humularia) reveals that Cannabis lost a sibling perhaps 20 million years ago (mya). Cannabis print fossils are rare (n = 3 worldwide), making it difficult to determine when and where she evolved. A molecular clock analysis with chloroplast [...]
