Australian researchers assessed the association between cannabis use and metabolic syndrome in a nationally representative random sampling of 1,813 subjects. Metabolic syndrome was identified in 63 percent of non-users (defined as no cannabis use over the past year) compared to only 43.5 percent of frequent users (defined as having used cannabis at least once per week for 52 weeks).
Authors concluded: “Participants who reported using cannabis in the previous 12 months were significantly less likely than non-users to have the metabolic syndrome. This association remained significant for frequent users … after adjustment for a range of potential confounders, including lifestyle … and sociodemographic characteristics. … [T]hese data suggest that (cannabis) may … have a cardiometabolic protective effect.”
A 2015 assessment of US cannabis consumers and non-users published in The American Journal of Medicine previously reported that those who consume cannabis are 50 percent less likely to suffer from metabolic syndrome as compared to those who do not. The findings are consistent with those of previous observational studies showing an inverse relationship between cannabis use and diabetic markers, and support population data documenting that those who use cannabis typically posses smaller waist circumference and lower body mass index as compared to abstainers.
