Marijuana use fights diabetes and lowers waist fat

The irrational opponents of marijuana legalization are having a harder and harder time of making the case that using it is harmful when we see that marijuana smokers suffer from less obesity and have significant protection from developing diabetes. Therefore, encouraging adult use of marijuana will work to lower our national health-care costs. Am J Med. 2013 May 9.

Epidemiologic studies have found lower prevalence rates of obesity and diabetes mellitus in marijuana users compared with people who have never used marijuana, suggesting a relationship between cannabinoids and peripheral metabolic processes. To date, no study has investigated the relationship between marijuana use and fasting insulin, glucose, and insulin resistance.METHODS:We included 4657 adult men and women from the National Health and Nutrition Examination Survey from 2005 to 2010. Marijuana use was assessed by self-report in a private room. Fasting insulin and glucose were measured via blood samples after a 9-hour fast, and homeostasis model assessment of insulin resistance HOMA-IR was calculated to evaluate insulin resistance. Associations were estimated using multiple linear regression, accounting for survey design and adjusting for potential confounders.RESULTS:Of the participants in our study sample, 579 were current marijuana users and 1975 were past users. In multivariable adjusted models, current marijuana use was associated with 16% lower fasting insulin levels 95% confidence interval [CI], -26, -6 and 17% lower HOMA-IR 95% CI, -27, -6. We found significant associations between marijuana use and smaller waist circumferences. Among current users, we found no significant dose-response.CONCLUSIONS:We found that marijuana use was associated with lower levels of fasting insulin and HOMA-IR, and smaller waist circumference.
