The Trouble with CBD Oil Arno Hazekamp Medical Cannabis and Cannabinoids, 2018, 1, 65–72 DOI: 10.1159/000489287 Abstract In just a few years, cannabidiol (CBD) has become immensely popular around the world. After initially being discovered as an effective self-medication for Dravet syndrome in children, CBD is now sold and used to treat a wide range of medical conditions and lifestyle diseases. The cannabinoid CBD, a non psychoactive isomer of the more infamous tetrahydrocannabinol (THC), is available in a growing number of administration modes, but the most commonly known is CBD oil. There are currently dozens, if not hundreds, of producers and sellers of CBD oils [...]

Freeman, Chandni Hindocha, Grainne Schafer, Chelsea Gardner and H. Valerie Curran Translational Psychiatry, 2018, 8, 181 DOI 10.1038/s41398-018-0191-x https://www.researchgate.net/publication/264860201 Abstract The main active ingredient in cannabis, delta-9-tetrahydrocannabinol (THC), can acutely induce psychotic symptoms and impair episodic and working memory. Another major constituent, cannabidiol (CBD), may attenuate these effects. This study aimed to determine the effects of THC and CBD, both alone and in combination on psychotic symptoms and memory function. A randomised, double-blind crossover design compared the effects of (i) placebo, (ii) THC 8mg, (iii) CBD [...]

RUSSO Frontiers in Integrative Neuroscience, 18 October 2018 https://doi.org/10.3389/fnint.2018.00051 Abstract : Neurological therapeutics have been hampered by its inability to advance beyond symptomatic treatment of neurodegenerative disorders into the realm of actual palliation, arrest or reversal of the attendant pathological processes. While cannabis-based medicines have demonstrated safety, efficacy and consistency sufficient for regulatory approval in spasticity in multiple sclerosis (MS), and in Dravet and Lennox-Gastaut Syndromes (LGS), many therapeutic challenges remain. This review will examine the intriguing promise that recent discoveries regarding cannabis-based medicines offer to neurological therapeutics by incorporating the neutral phytocannabinoids tetrahydrocannabinol (THC), cannabidiol [...]

Onaivi Molecules, 2018, 23, 1836; doi : 10.3390/molecules23081836 Abstract : CB2 cannabinoid receptor (CB2R) gene is associated with depression. We investigated the gene-environment interaction between CB2R function and diverse stressors. First, anxiety-like behavior during chronic-mild-stress (CMS) was evaluated in C57BL/6JJmsSlc mice following treatment with CB2R agonist JWH015 or inverse-agonist AM630. Second, locomotor activity and anxiety-like behavior were measured following exposure to an immune poly I:C stressor. Gene expressions of HPA axis related molecules, Fkbp5, Nr3c1 and Crf and [...]

The transformation of cannabinoids from herbal preparations into highly regulated prescription drugs is therefore progressing rapidly. The development of such drugs requires well-controlled clinical trials to be carried out in order to objectively establish therapeutic efficacy, dose ranges and [...]

Furthermore, increasing Δ9-tetrahydrocannabinol (THC) in high-potency cannabis is accompanied by a decrease in cannabidiol (CBD), thus [...]

Ditre Cannabis and Cannabinoid Research, Volume 2.1, 2017 DOI: 10.1089/can.2017.0017 Abstract Introduction : Cannabis has been used for medical purposes across the world for centuries. As states and countries implement medical and recreational cannabis policies, increasing numbers of people are using cannabis pharmacotherapy for pain. There is a theoretical rationale for cannabis' efficacy for pain management, although the subjective pain relief from cannabis may not match objective measurements of analgesia. As more patients turn to cannabis for pain relief, there is a need for additional scientific evidence [...]

Dr Vanina Popova In the global study, those who received a newly initiated oral antidepressant combined with esketamine nasal spray (56 or 84 mg) showed a 4-point greater improvement from baseline to 4 weeks on the Montgomery-Åsberg Depression Rating Scale (MADRS) total score than those who received an antidepressant plus placebo, meeting the study's primary endpoint. In addition, the response rate was nearly 70% [...]
Lire la suiteCANNABIS ET CANNABIDIOL : Éléments de Compréhension Dr Sarah Lejczak La Lettre du RESPADD, 35, avril 2019 Depuis 5000 ans, le cannabis ruderalids, sativa ou indica est utilisé dans la pharmacopée humaine de manière informelle pour ses différentes propriétés antihémétiques, antiépileptiques, antispastiques, antalgiques, anxiolytiques, antihypertensives, etc. (1). Suite à son introduction dans l’arsenal pharmaceutique moderne au XIXème siècle et les dérives d’utilisation récréative au cours du XXème siècle, son utilisation a été interdite et reste très controversée de nos jours. Des extraits cannabinoïdes (2) (Delta-9-tetrahydrocannabinol (Δ-9-THC), cannabidiol (CBD) et cannabinol (CBN) majoritairement) de la plante ou fabriqués synthétiquement sont utilisés depuis 1985 en tant que médicaments.
