Experimental Endozoochory of Cannabis sativa Achenes, John M. McPartland and Steve G. Naraine, 2018

Experimental Endozoochory of Cannabis sativa Achenes John M. McPartland and Steve G. Naraine Medical Cannabis and Cannabinoids, 2018, 1, 96–103 DOI: 10.1159/000492971 https://www.karger.com/Article/FullText/492971 Abstract : The mechanism by which Cannabis sativa dispersed from its center of origin remains an open question. The literature provides many hypotheses, which we review for the first time, but experiments are few. Darwin was interested in zoochory – the transport of plants by animals. He demonstrated endozoochory (transport of seeds via animal digestive systems) of C. sativa achenes (seeds) by carrier pigeons, but he did not quantify achene survival rates. We assessed mammalian endozoochory in a triplicate experiment: feeding C. sativa [...]

Cannabinoid Hyperemesis, Joseph V. Pergolizzi Jr.,  Jo Ann LeQuang & John F. Bisney, 2018

Cannabinoid Hyperemesis Joseph V. Pergolizzi Jr.,  Jo Ann LeQuang, John F. Bisney Medical Cannabis and Cannabinoids, 2018, 1, 73–95 DOI: 10.1159/000494992 https://www.karger.com/Article/FullText/494992 Abstract : Cannabinoid hyperemesis syndrome (CHS) is a paradoxical condition in which a long-term cannabis user suffers an episode of intractable vomiting that may last days separated by longer asymptomatic periods of weeks or months. Cannabinoids are often utilized for their antiemetic properties, so CHS can be a puzzling condition, and the diagnosis of CHS may be disputed by patients. Unlike other cyclic vomiting syndromes, CHS can be relieved by hot showers or topical capsaicin. Abstinence from cannabinoids causes CHS to resolve, sometimes in [...]

The Trouble with CBD Oil, Arno Hazekamp, 2018

The Trouble with CBD Oil Arno Hazekamp Medical Cannabis and Cannabinoids, 2018, 1, 65–72 DOI: 10.1159/000489287   Abstract In just a few years, cannabidiol (CBD) has become immensely popular around the world. After initially being discovered as an effective self-medication for Dravet syndrome in children, CBD is now sold and used to treat a wide range of medical conditions and lifestyle diseases. The cannabinoid CBD, a non psychoactive isomer of the more infamous tetrahydrocannabinol (THC), is available in a growing number of administration modes, but the most commonly known is CBD oil. There are currently dozens, if not hundreds, of producers and sellers of CBD oils [...]

Individual and combined effects of acute delta-9-tetrahydrocannabinol and cannabidiol on psychotomimetic symptoms and memory function, Celia J. A. Morgan et al., 2018

Individual and combined effects of acute delta-9-tetrahydrocannabinol and cannabidiol on psychotomimetic symptoms and memory function Celia J. A. Morgan, Tom P. Freeman, Chandni Hindocha, Grainne Schafer, Chelsea Gardner and H. Valerie Curran Translational Psychiatry, 2018, 8, 181 DOI 10.1038/s41398-018-0191-x https://www.researchgate.net/publication/264860201   Abstract The main active ingredient in cannabis, delta-9-tetrahydrocannabinol (THC), can acutely induce psychotic symptoms and impair episodic and working memory. Another major constituent, cannabidiol (CBD), may attenuate these effects. This study aimed to determine the effects of THC and CBD, both alone and in combination on psychotic symptoms and memory function. A randomised, double-blind crossover design compared the effects of (i) placebo, (ii) THC 8mg, (iii) CBD [...]

Cannabis Therapeutics and the Future of Neurology, Ethan B. Russo, 2018

Cannabis Therapeutics and the Future of Neurology Ethan B. RUSSO Frontiers in Integrative Neuroscience, 18 October 2018 https://doi.org/10.3389/fnint.2018.00051 Abstract : Neurological therapeutics have been hampered by its inability to advance beyond symptomatic treatment of neurodegenerative disorders into the realm of actual palliation, arrest or reversal of the attendant pathological processes. While cannabis-based medicines have demonstrated safety, efficacy and consistency sufficient for regulatory approval in spasticity in multiple sclerosis (MS), and in Dravet and Lennox-Gastaut Syndromes (LGS), many therapeutic challenges remain. This review will examine the intriguing promise that recent discoveries regarding cannabis-based medicines offer to neurological therapeutics by incorporating the neutral phytocannabinoids tetrahydrocannabinol (THC), cannabidiol [...]
