Study: No Link Between Cumulative Cannabis Use And Kidney Disease

MASSACHUSETTS: The cumulative use of cannabis is not associated with adverse effects on kidney function, according to clinical data published in The American Journal of Medicine.

Harvard investigators assessed the relationship between marijuana use and renal function in a cohort of 13,995 adults between the ages of 18 and 59. Current marijuana users possessed no significant differences in any measures of kidney function as compared to past users and never users.

“Marijuana use did not have a significant association with serum creatinine, eGFR (estimated glomerular filtration rate), or odds of having stage 2 or greater chronic kidney disease,” they concluded.

The study’s findings are similar to those of a 2017 University of California study which reported that the long-term use of cannabis was not associated with symptoms of kidney disease.
