Authors: Marta Di Forti, Arianna Marconi, Elena Carra, Sara Fraietta, Antonella Trotta, Matteo Bonomo, et al
The Lancet Psychiatry, March 2015

BACKGROUND: The risk of individuals having adverse effects from drug use (eg, alcohol) generally depends on the frequency of use and potency of the drug used. We aimed to investigate how frequent use of skunk-like (high-potency) cannabis in south London affected the associatio…

Synthetic and natural cannabinoids: the cardiovascular risk.

Authors: Ethan B. Russo
The British Journal of Cardiology, March 2015

Cannabis has been employed medicinally and recreationally for thousands of years, but it was not until the 1960s that the structure and pharmacology of its primary phytocannabinoid components, cannabidiol (CBD) and tetrahydrocannabinol (THC) were identified, and another genera…

Role of Endocannabinoid Activation of Peripheral CB1 Receptors in the Regulation of Autoimmune Disease.

Authors: Jessica Margaret Sido, Prakash S. Nagarkatti, Mitzi Nagarkatti
International Reviews of Immunology, 2015

The impact of the endogenous cannabinoids (AEA, 2-AG, PEA, and virodamine) on the immune cell expressed cannabinoid receptors (CB1, CB2, TRPV-1, and GPR55) and consequent regulation of immune function is an exciting area of research with potential implications in the preventio…

Authors: Ruth Gallily, Zhannah Yekhtin, Lumír Ondřej Hanuš
Pharmacology & Pharmacy, 2015

Cannabidiol (CBD), a major constituent of Cannabis, has been shown to be a powerful anti-in- flammatory and anti-anxiety drug, without exerting a psychotropic effect. However, when given either intraperitoneally or orally as a purified product, a bell-shaped dose-response was…

TRP channel cannabinoid receptors in skin sensation, homeostasis, and inflammation.

Authors: Michael J. Caterina
ACS Chemical Neuroscience, 19 November 2014

In the skin, cannabinoid lipids, whether of endogenous or exogenous origin, are capable of regulating numerous sensory, homeostatic, and inflammatory events. Although many of these effects are mediated by metabotropic cannabinoid receptors, a growing body of evidence has revea…

Cannabinoid CB2 receptors modulate midbrain dopamine neuronal activity and dopamine-related behavior in mice.

Authors: Hai-Ying Zhang, Ming Gao, Qing-Rong Liu, Guo-Hua Bi, Xia Li, Hong-Ju Yang, et al
Proceedings of the National Academy of Sciences, 18 November 2014

Cannabinoid CB2 receptors (CB2Rs) have been recently reported to modulate brain dopamine (DA)-related behaviors; however, the cellular mechanisms underlying these actions are unclear. Here we report that CB2Rs are expressed in ventral tegmental area (VTA) DA neurons and functi…
