Δ 9‑Tetrahydrocannabinol Toxicity and Validation of Cannabidiol on Brain Dopamine Levels : An Assessment on Cannabis Duplicity, Swapnali Chetia & Gaurab Borah, 2020

Δ 9‑Tetrahydrocannabinol Toxicity and Validation of Cannabidiol on Brain Dopamine Levels : An Assessment on Cannabis Duplicity Swapnali Chetia · Gaurab Borah Natural Products and Bioprospecting, 2020, 10, 285–296 doi : 10.1007/s13659-020-00263-z   Abstract Δ9-tetrahydrocannabinol (THC) of cannabis is the main psychoactive component which is a global significant concern to human health. Evaluation on THC reported its drastic effect on the brain dopaminergic (DAergic) system stimulating mesolimbic DA containing neurons thereby increasing the level of striatal DA. Cannabidiol (CBD), with its anxiolytic and anti-psychotic property, is potent to ameliorate the THC-induced DAergic variations. Legal authorization of cannabis use and its analogs in most countries led to [...]

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 [...]

The Intricate Influence of the Placebo Effect on Medical Cannabis and Cannabinoids, Jürg Gertsch, 2018

The Intricate Influence of the Placebo Effect on Medical Cannabis and Cannabinoids Jürg Gertsch Medical Cannabis Cannabinoids,  2018, 1, 60–64 Doi : 10.1159/000489291 Abstract The botanical drug cannabis flos (inflorescence of Cannabis sativa L.) has a unique popular status as being a potent recreational drug and bona fide universal remedy (panacea). Generally, cannabinoids exert therapeutic effects in a broad range of pathophysiologies related to inflammation, pain, metabolic and stress-related conditions in preclinical animal models. However, the translation of such data to humans still lacks an evidence-based foundation. Motivated by the booming cannabis manufacturing industry and the increasing worldwide self-therapy by patients, there are cumulative accounts [...]

Cannabinoids and the Coronavirus, Kevin P. Hill, 2020

Cannabinoids and the Coronavirus Kevin P. Hill Cannabis and Cannabinoid Research, 2020, Volume 5, Number 2, Doi : 10.1089/can.2020.0035   Introduction These are uncertain times as we attempt to manage our lives during the Coronavirus Covid-19 pandemic. It is not surprising, as possible treatments for Covid-19 are discussed, that people wonder about a role for cannabinoids, another topic associated with a lack of clarity about their therapeutic efficacy. Patients commonly ask clinicians about the benefits and risks of cannabinoids and now patients have begun to ask about cannabinoids as they relate to Covid-19. This interest creates an opportunity to strengthen the therapeutic alliance between patients and [...]

L’huile de chanvre contient-elle du THC et du CBD ?, Newsweed, 11 février 2020, Aurélien BERNARD

L’huile de chanvre contient-elle du THC et du CBD ? Newsweed, 11 février 2020 Aurélien BERNARD https://www.newsweed.fr/huile-chanvre-contient-thc-cbd/   L’huile de chanvre, extraite des graines, est une source précieuse d’omega 3 et 6 et de nutriments dans l’alimentation quotidienne. Sa valeur nutritionnelle et thérapeutique pourrait néanmoins aussi être attribuée à sa composition en cannabinoïdes qui, si faiblement présents, existent quand même. Dans une étude de 2019, plusieurs cannabinoïdes ont été détectés dans l’huile de graines de chanvre et permettent de déterminer des différences dans leur composition chimique. Bien que le CBDA et le CBD soient prédominants dans les dix huiles étudiées, 20 autres cannabinoïdes «mineurs» ont été [...]

Changing landscape of cannabis : novel products, formulations, and methods of administration, Tory R Spindle et al., 2019

Changing 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, [...]
