Neither current nor the long-term cumulative use of cannabis is associated with negative effects on the kidneys, according to longitudinal data published online ahead of print in the Clinical Journal of the American Society of Nephrology.

Investigators at the San Francisco Veterans Affairs Medical Center and the University of California, San Francisco assessed the impact of past and current marijuana use over a ten-year period on estimated glomerular filtration rate (eGFR) – a screening measurement used in the early detection of kidney damage.

Authors reported, “[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).”
