Sichuan, China: Men who consume cannabis are far less likely than non-users to experience kidney stones, according to data published in the journal Frontiers in Pharmacology.
A team of Chinese investigators assessed the relationship between cannabis use and kidney stones in a representative sample of over 14,000 US subjects between the ages of 20 and 59.
After adjusting for potential confounders, researchers reported that marijuana use among men was inversely correlated with kidney stones (OR = 0.72). Men who consumed cannabis most frequently experienced the lowest risk (OR = 0.62). Similar trends were not identified among females.
Authors concluded: “To our knowledge, this study is the first cross-sectional study to explore the association between marijuana use and the risk of kidney stones from the population-based NHANES [National Health and Nutrition Examination Survey] dataset. Taken together, our findings suggested that regular marijuana male users were related to a lower risk of kidney stones. Further studies are warranted to investigate the dose and type associations of marijuana with kidney stones.”
