Effect of D-9-Tetrahydrocannabinol and Cannabidiol on Nocturnal Sleep and Early-Morning Behavior in Young Adults Anthony N. Nicholson, MD, PhD, Claire Turner, BSc, Barbara M. Stone, PhD, and Philip J. Robson, MDy Journal of Clinical Psychopharmacology, 2004, Volume 24, Number 3, 305-313. Doi : 10.1097/01.jcp.0000125688.05091.8f Abstract : The effects of cannabis extracts on nocturnal sleep, earlymorning performance, memory, and sleepiness were studied in 8 healthy volunteers (4 males, 4 females; 21 to 34 years). The study was double-blind and placebo-controlled with a 4-way crossover design. The 4 treatments were placebo, 15 mg D-9-tetrahydro-cannabinol (THC), 5 mg THC combined with 5 mg cannabidiol (CBD), and 15 mg [...]
Lire la suitePlant cannabinoids : a neglected pharmacological treasure trove Raphael Mechoulam British Journal of Pharmacology, 2005, 146, 913–915 doi : 10.1038/sj.bjp.0706415 Most of the cannabinoids in Cannabis sativa L. have not been fully evaluated for their pharmacological activity. A publication in this issue presents evidence that a plant cannabinoid, D9-tetrahydro-cannabivarin is a potent antagonist of anandamide, a major endogenous cannabinoid. It seems possible that many of the non-psychoactive constituents of this plant will be of biological interest. Keywords : Anandamide; CB1 receptor antagonist; CB2 receptor antagonist; mouse vas deferens; D9 tetrahydrocannabinol; D9-tetrahydrocannabivarin; -(þ)-(R)- WIN55212 Cannabis sativa L. produces more than 60 terpeno-phenols that have not been detected [...]
Lire la suiteEfficacy of Dronabinol for Acute Pain Management in Adults with Traumatic Injury : Study Protocol of A Randomized Controlled Trial Claire Swartwood, Kristin Salottolo, Robert Madayag, David Bar-Or Brain Sciences, 2020, 10, 161, 1-9. Doi : 10.3390/brainsci10030161 Abstract Delta-9-tetrahydrocannabinol (D9-THC) and other cannabinoids present in cannabis (marijuana) have been shown to affect the normal inhibitory pathways that influence nociception in humans. The potential benefits of cannabinoids as an analgesic are likely greatest in hyperalgesic and inflammatory states, suggesting a role as a therapeutic agent for treating acute pain following injury. Dronabinol is a licensed form of D9-THC. The primary objective of this single center randomized [...]
Lire la suiteCannabinoids : the lows and the highs of chemotherapy-induced nausea and vomiting Toni Leigh Mortimer, Tom Mabin & Anna-Mart Engelbrecht Future Oncology, 2019 Doi : 10.2217/fon-2018-0530 Despite remaining one of the most widely abused drugs worldwide, Cannabis sativa exhibits remarkable medicinal properties. The phytocannabinoids, cannabidiol and -9-tetrahydrocannabinol, reduce nausea and vomiting, particularly during chemotherapy. This is attributed to their ability to reduce the release of serotonin from enterochromaffin cells in the small intestine, which would otherwise orchestrate the vomiting reflex. Although there are many preclinical and clinical studies on the effects of -9- tetrahydrocannabinol during nausea and vomiting, little is known about the role [...]

Science/Homme: Le THC peut être utile dans le trouble de stress post-traumatique (IACM 30 mars 2020) Lors d’une étude contrôlée par placebo avec 71 participants, composée de 3 groupes (25 témoins sains, 27 adultes exposés à un traumatisme sans trouble de stress post-traumatique et 19 patients souffrant d'un trouble de stress post-traumatique), de faibles doses de THC ont réduit la réactivité liée à la menace dans une certaine [...]

Doi : 10.1111/bph.14226 BACKGROUND AND PURPOSE Cannabidiol (CBD) represents a promising therapeutic tool for treating cannabis use disorder (CUD). This study aimed to evaluate the effects of CBD on the behavioural and gene expression alterations induced by spontaneous cannabinoid withdrawal. EXPERIMENTAL APPROACH Spontaneous cannabinoid withdrawal was evaluated 12 h after cessation of CP-55,940 treatment (0.5 mg·kg1 every 12 h, i.p.; 7 days) in C57BL/6J mice. The effects of CBD (5, 10 and 20 mg·kg1, i.p.) on withdrawal-related behavioural signs were evaluated by [...]

Loflin, Suman Chandra and Ryan Vandrey International Review of Psychiatry, 2018, VOL. 30, NO. 3, 277–284 Doi : 10.1080/09540261.2018.1474730 ABSTRACT Accumulating evidence suggests that the endocannabinoid system is a promising target for the treatment of a variety of health conditions. Two paths of cannabinoid drug development have emerged. One approach is focused on developing medications that are directly derived from the cannabis plant. The other utilizes a single molecule approach whereby individual phytocannabinoids or novel cannabinoids with therapeutic potential are identified and synthesized for pharmaceutical [...]

Doi : 10.1089/can.2019.0060 Abstract Background : The possibility of cannabidiol (CBD) to be used as an antiviral or to treat viral diseases has received limited attention so far, despite the growing number of claims that CBD could be used for the treatment of viral infection-related conditions. Aim and Methods : Therefore, we systematically retrieved and critically evaluated the scientific literature available on PubMed and the claims on the Internet, to assess the current state of knowledge on the use of [...]
