5-HT1A receptors are involved in the cannabidiol-induced attenuation of behavioural and cardiovascular responses to acute restraint stress in rats Leonardo B.M. Resstel, Rodrigo F. Tavares, Sabrina F.S. Lisboa, Sâmia R.L. Joca, Fernando M.A. Corrêa and Francisco S. Guimarães British Journal of Pharmacology, 2009, 156, 181–188; doi : 10.1111/j.1476-5381.2008.00046.x Background and purpose : Cannabidiol (CBD) is a non-psychotomimetic compound from Cannabis sativa which induces anxiolytic- and antipsychotic-like effects in rodents. These effects could be mediated by facilitation of the endocannabinoid system or by the activation of 5-HT1A receptors. As either of these mechanisms could promote adaptation to inescapable stress, the aim of the present work [...]

Barratt, Tom Decorte, Pekka Hakkarainen, Simon Lenton, Gary Potter, Bernd Werse and Chris Wilkins Drugs and Alcohol Today, 2019, 19, (4), 251-256, Doi : 10.1108/DAT-06-2019-0021 Abstract Purpose – It is conceivable that cannabis cultivators who grow for medical purposes aim to improve the therapeutic index of their cannabis by attempting to produce particular concentrations of CBD and/or THC. The purpose of this paper is to examine whether small-scalemedical cannabis growers differ fromthose growing for recreational reasons in terms of self-assessed concentrations of THC and CBD [...]

We aimed [...]

Although studies suggest that the endocannabinoid system has immunomodulatory properties, there remains a paucity of information on the effects of cannabinoids on immunity and on outcomes of infection and injury.

Welling, Lei Liu, Arno Hazekamp, Ashley Dowell, Graham J. King Medical Cannabis & Cannabinoids, 2019, 2, 1–13 Doi : 10.1159/000496868 Abstract The plant genus Cannabis is a prolific producer of unique pharmaceutically relevant metabolites, commonly referred to as cannabinoids. Robust and standardised methods for the quantification of cannabinoids within botanical and drug forms is a critical step forward for an emerging Cannabis- based pharmaceutical industry, which is poised for rapid expansion. Despite a growing body of analytical methods for the quantification of cannabinoids, few have [...]

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 [...]
