Stokes, and Andrea L. Small-Howard Cannabis and Cannabinoid Research, Volume X, Number X, 2019 Mary Ann Liebert, Inc. DOI: 10.1089/can.2018.0063 Abstract Introduction : Medical cannabis patients receive clinical benefits from the secondary metabolites of the plant, which contain a variety of cannabinoids and terpenoids in combinations that can be used to classify the chemovars. State-regulated medical cannabis programs rely on breeder-reported ‘‘strain’’ names both within diversion control systems and to [...]

Fischedick Drug Testing and Analysis, 2012, (wileyonlinelibrary.com) DOI 10.1002/dta.407, Copyright © 2012 John Wiley & Sons, Ltd. Abstract : The medicinal use of Cannabis is increasing as countries worldwide are setting up official programs to provide patients with access to safe sources of medicinal-grade Cannabis. An important question that remains to be answered is which of the many varieties of Cannabis should be made available for medicinal use. Drug varieties of Cannabis are commonly distinguished through the use of popular names, with a major distinction being made between Indica and Sativa types. Although more than [...]
Lire la suiteThe Case for the Entourage Effect and Conventional Breeding of Clinical Cannabis : no "Strain", no Gain Ethan B. Russo, Frontiers in Plant Science, 2019, Volume 9, Article 1969, 1-8. doi : 10.3389/fpls.2018.01969 The topic of Cannabis curries controversy in every sphere of influence, whether politics, pharmacology, applied therapeutics or even botanical taxonomy. Debate as to the speciation of Cannabis, or a lack thereof, has swirled for more than 250 years. Because all Cannabis types are eminently capable of cross-breeding to produce fertile progeny, it is unlikely that any clear winner will emerge between the “lumpers” vs. “splitters” in this taxonomical debate. This is [...]

Lantela, Frontiers in Neuroscience, 2018, 12, article 730. https://doi.org/10.3389/fnins.2018.00730 Abstract : Cannabis sativa is a medicinal herb with a diverse range of chemotypes that can exert both anxiolytic and anxiogenic effects on humans. Medical cannabis patients receiving organically grown cannabis from a single source were surveyed about the effectiveness of cannabis for treating anxiety. Patients rated cannabis as highly effective overall for treating anxiety with an average score of 8.03 on a Likert scale of 0 to 10 (0 = not effective, [...]
