According to a study published in the journal Phytotherapy Research, adult marijuana users are considerably less likely than non-consumers to develop type 2 diabetes.
For the study researchers from the Tabriz University of Medical Science conducted a meta-analysis covering more than 478,000 subjects. The study was conducted “to evaluate the association between cannabis use and type 2 diabetes mellitus (T2DM).”
Randomized control trials, cohort, and case-control studies investigating the relationship between cannabis consumption and diabetes mellitus type 2 were included.
“A meta-analysis of seven studies, containing 11 surveys and 4 cohorts, revealed that the odds of developing T2DM in individuals exposed to cannabis was 0.48 times (95% CI: 0.39 to 0.59) lower than in those without cannabis exposure”, found the study.
Researchers say that to their knowledge, this study presents “the most up-to-date evidence on the association between cannabis consumption and T2DM”.
They say that “Given the rising trend of cannabis consumption, and legalization of cannabis consumption there is an increasing need to design prospective longitudinal randomized studies investigating the honest effects of cannabis consumption and providing practical guidelines to manage cannabis usage.”
A separate study published earlier this year (a double-blind, placebo-controlled clinical trial) found that sublingual spray that contains both CBD and THC “could be a new therapeutic agent for lipid and glycemic control in diabetic patients”.
