A Systematic Review of the Effectiveness of Medical Cannabis for Psychiatric, Movement and Neurodegenerative Disorders.

Authors: Keane Lim, Yuen Mei See, and Jimmy Lee
Clinical Psychopharmacology and Neuroscience, 30 November 2017

The discovery of endocannabinoid’s role within the central nervous system and its potential therapeutic benefits have brought forth rising interest in the use of cannabis for medical purposes. The present review aimed to synthesize and evaluate the available evidences on the e…

Authors: Yacov Balash, Lihi Bar-Lev Schleider, Amos Korczyn, Herzel Shabtai, Judith Knaani, et al
Clinical Neuropharmacology, November/December 2017

BACKGROUND: The use of medical cannabis (MC) is controversial. Support for its benefits is based on small clinical series. OBJECTIVE: The aim of this study was to report the results of a standardized interview study that retrospectively assessed the effects of MC on symptoms o…

BMC Veterinary Research, 6 November 2017

BACKGROUND: Cannabis-based drugs have been shown to be effective in inflammatory diseases. A number of endocannabinoids including N- arachidonoylethanolamide (anandamide, AEA) and 2-arachidonyl glycerol (2-AG) with activity at the cannabinoid receptors (CBR) CBR1 and CBR2, hav…

Oral administration of cannabis with lipids leads to high levels of cannabinoids in the intestinal lymphatic system and prominent immunomodulation.

Authors: Atheer Zgair, Jong Bong Lee, Jonathan C. M. Wong, Dhiaa A. Taha, Jehan Aram, et al
Scientific Reports, 6 November 2017

Cannabidiol (CBD) and ∆9-tetrahydrocannabinol (THC) have well documented immunomodulatory effects in vitro, but not following oral administration in humans. Here we show that oral co-administration of cannabinoids with lipids can substantially increase their intestinal lympha…

Masturbation to Orgasm Stimulates the Release of the Endocannabinoid 2-Arachidonoylglycerol in Humans.

Authors: Johannes Fuss, Laura Bindila, Klaus Wiedemann, Matthias K. Auer, Peer Briken, Sarah V. Biedermann
Journal of Sexual Medicine, November 2017

BACKGROUND: Endocannabinoids are critical for rewarding behaviors such as eating, physical exercise, and social interaction. The role of endocannabinoids in mammalian sexual behavior has been suggested because of the influence of cannabinoid receptor agonists and antagonists o…

Physicians-in-training are not prepared to prescribe medical marijuana.

Authors: Anastasia B. Evanoff, Tiffany Quan, Carolyn Dufault, Michael Awad, Laura Jean Bierut
Drug and Alcohol Dependence, 1 November 2017

BACKGROUND: While medical marijuana use is legal in more than half of U.S. states, evidence is limited about the preparation of physicians-in-training to prescribe medical marijuana. We asked whether current medical school and graduate medical educational training prepare phys…

Standardized Cannabis sativa extract attenuates tau and stathmin gene expression in the melanoma cell line.

Authors: Golnaz Vaseghi, Mohamad Javad Taki, Shaghayegh Haghjooy Javanmard
Iranian journal of basic medical sciences, October 2017

OBJECTIVES: Metastasis is the main cause of death in patients with melanoma. Cannabis-based medicines are effective adjunctive drugs in cancer patients. Tau and Stathmin proteins are the key proteins in cancer metastasis. Here we have investigated the effect of a standardized…

Endocannabinoid system in neurodegenerative disorders.

Authors: Balapal S. Basavarajappa, Madhu Shivakumar, Vikram Joshi, Shivakumar Subbanna
Journal of Neurochemistry, September 2017

Most neurodegenerative disorders (NDDs) are characterized by cognitive impairment and other neurological defects. The definite cause of and pathways underlying the progression of these NDDs are not well-defined. Several mechanisms have been proposed to contribute to the develo…

European Neuropsychopharmacology, August 2017

Adults with ADHD describe self-medicating with cannabis, with some reporting a preference for cannabis over ADHD medications. A small number of psychiatrists in the US prescribe cannabis medication for ADHD, despite there being no evidence from randomised controlled studies…

Marijuana and pregnancy: objective education is good, but biased education is not.

American Journal of Obstetrics and Gynecology, August 2017

To the Editors: We read with interest the article by Chasnoff, 1 which concluded that physicians should be educated about the negative effects of marijuana use during pregnancy and should discourage its use by pregnant women and women considering becoming pregnant. In our view…

Spatial distribution of cannabinoid receptor type 1 (CB1) in normal canine central and peripheral nervous system.

Authors: Jessica Freundt-Revilla, Kristel Kegler, Wolfgang Baumgärtner, Andrea Tipold
PLoS One, 10 July 2017

The endocannabinoid system is a regulatory pathway consisting of two main types of cannabinoid receptors (CB1 and CB2) and their endogenous ligands, the endocannabinoids. The CB1 receptor is highly expressed in the central and peripheral nervous systems (PNS) in mammalians and…
