Longitudinal data published in the Clinical Journal of the American Society of Nephrology has determined neither current nor long-term cumulative use of cannabis contributes to kidney disease. In the study, investigators from the San Francisco Veterans Affairs Medical Center and the University of California, San Francisco looked at the impact of past and current marijuana use over the course of ten years on estimated glomerular filtration rate (eGFR), which is a screening measurement that detects early kidney damage. Authors explained, “[O]ur findings did not demonstrate a longitudinal association between marijuana use and eGFR change, rapid eGFR decline, or prevalent albuminuria (the presence of albumin in the urine, typically as a symptom of kidney disease).”
