Clinical and Preclinical Evidence for Functional Interactions of Cannabidiol and Δ9-Tetrahydrocannabinol, Douglas L Boggs et al., 2018

Clinical and Preclinical Evidence for Functional Interactions of Cannabidiol and Δ9-Tetrahydrocannabinol Douglas L Boggs, Jacques D Nguyen, Daralyn Morgenson, Michael A Taffe and Mohini Ranganathan Neuropsychopharmacology Reviews, 2018, 43, 142–154. doi : 10.1038/npp.2017.209; The plant Cannabis sativa, commonly called cannabis or marijuana, has been used for its psychotropic and mind-altering side effects for millennia. There has been growing attention in recent years on its potential therapeutic efficacy as municipalities and legislative bodies in the United States, Canada, and other countries grapple with enacting policy to facilitate the use of cannabis or its constituents for medical purposes. There are 4550 chemical compounds and 4100 phytocannabinoids [...]

Self-Medication with Cannabis, Chapter 17, Arno Hazekamp and George Pappas, 2019

Self-Medication with Cannabis, Chapter 17 Arno Hazekamp and George Pappas April 2019, 17-Pertwee-Chap17.indd 319 https://www.researchgate.net/profile/Arno_Hazekamp/research   17.1 Introduction The medicinal use of cannabis is slowly gaining a more general acceptance worldwide. Canada (since 2001) and the Netherlands (since 2003) have government-run programs, in which quality-controlled herbal cannabis is supplied by specialized and licensed companies. Several other countries are now setting up their own programs (Israel, Czech Republic, Switzerland) or import products from the Dutch program (Italy, Finland, Germany, Switzerland). In the US, despite strong opposition by the federal government, so far 18 states including the District of Columbia have introduced laws to permit “medical marijuana use” [...]

Determination of cannabinoids in Cannabis sativa L. samples for recreational, medical, and forensic purposes by reversed-phase liquid chromatography-ultraviolet detection, Sanja Zivovinovic, et al., 2018

Determination of cannabinoids in Cannabis sativa L. samples for recreational, medical, and forensic purposes by reversed-phase liquid chromatography-ultraviolet detection Sanja Zivovinovic, Ruth Alder, Martina D. Allenspach and Christian Steuer Journal of Analytical Science and Technology, 2018, 9, 27, 1-10 doi : 10.1186/s40543-018-0159-8   Abstract Background : Currently, an increasing demand of cannabis-derived products for recreational and medical use is observed. Therefore, the reliable and fast quantification of cannabinoids in hemp samples is essential for the control of product from Cannabis sativa, L. strains. In general, gas chromatography (GC) is the method of choice for the quantification of cannabinoids whereas this method is time consuming and the [...]

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 et al., 2009

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 [...]

Anti-inflammatory Effects of Lenabasum, a Cannabinoid Receptor Type 2 Agonist, on Macrophages From Cystic Fibrosis Abdullah A Tarique, Tama Evron, George Zhang, Mark A Tepper, Mohammed M Morshed, Isabella S G Andersen, Nelufa Begum, Peter D Sly, Emmanuelle Fantino Journal of Cystic Fibrosis, 2020, S1569-1993, (20), 30094-1 doi : 10.1016/j.jcf.2020.03.015. Abstract Background : Lenabasum is an oral synthetic cannabinoid receptor type 2 agonist previously shown to reduce the production of key airway pro-inflammatory cytokines known to play a role in cystic fibrosis (CF). In a double-blinded, randomized, placebo-control phase 2 study, lenabasum lowered the rate of pulmonary exacerbation among patients with CF. The present study was undertaken to investigate anti-inflammatory [...]

Activation of CB1R Promotes Lipopolysaccharide-Induced IL-10 Secretion by Monocytic Myeloid-Derived Suppressive Cells and Reduces Acute Inflammation and Organ Injury Jérémie Joffre, Che-Chung Yeh, Erika Wong, Mayuri Thete, Fengyun Xu, Ivana Zlatanova, Elliot Lloyd, Lester Kobzik, Matthieu Legrand, and Judith Hellman The Journal of Immunology, 2020, 204: 1–20. doi : 10.4049/jimmunol.2000213   Cannabis sativa and its principal components, D9-tetrahydrocannabinol (D9-THC) and cannabidiol, are increasingly being used to treat a variety of medical problems, including inflammatory conditions. 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.
