MedicalResearch.com: What is the background for this study? What are the main findings?
Response: Marijuana is becoming increasingly accepted in the United States, and animal studies suggest that marijuana could affect kidney function. However, data in humans are limited to case reports of acute kidney injury related to synthetic cannabinoid use and small cohort studies of relatively short duration.
Among 3,765 participants with normal kidney function in the Coronary Artery Risk Development in Young Adults or CARDIA study, my colleagues and I found that higher marijuana use was associated with lower kidney function at the start of the our study. However, we did not find that marijuana was associated with change in kidney function or albuminuria, which is a sign of kidney damage, over long-term follow-up.
