A naturally occurring analogue of THC — tetrahydrocannabivarin (THCV) — has positive metabolic effects in animal models of obesity, according to preclinical study data published online in June in the scientific journal Nutrition & Diabetes.
British researchers assessed the effects of THCV administration on dietary-induced and genetically modified obese mice. Authors reported that although its administration did not significantly affect food intake or body weight gain in any of the models, it did produce several metabolically beneficial effects, including reduced glucose intolerance, improved glucose tolerance, improved liver triglyceride levels, and increased insulin sensitivity.
Researchers concluded: “Based on these data, it can be suggested that THCV may be useful for the treatment of the metabolic syndrome and/or type 2 diabetes (adult onset diabetes), either alone or in combination with existing treatments. Given the reported benefits of another non-THC cannabinoid, CBD in type 1 diabetes, a CBD/THCV combination may be beneficial for different types of diabetes mellitus.”
Harvard Medical School researchers published observational data in the May, 2013 American Journal of Medicine reporting that subjects who regularly consume cannabis possess favorable indices related to diabetic control as compared to occasional or non-users. Writing in an accompanying commentary, the editor-in-chief stated that, “These are indeed remarkable observations that are supported, as the authors note, by basic science experiments that came to similar conclusions. … [T]he NIH and DEA [should] collaborate in developing policies to implement solid scientific investigations that would lead to information assisting physicians in the proper use and prescription of THC in its synthetic or herbal form.”
Observational trial data published in 2012 in the British Medical Journal previously reported that adults with a history of marijuana use had a lower prevalence of type 2 diabetes and possess a lower risk of contracting the disease than did those with no history of cannabis consumption, even after researchers adjusted for social variables such as subjects’ ethnicity and levels of physical activity.
Previously published preclinical data also indicates that the administration of cannabidiol (CBD) halts the development of type 1 (juvenile) diabetes in genetically predisposed mice. — West Coast Leaf News Service
