Research published in The American Journal of Medicine provides evidence suggesting that there is no detrimental effect of infrequent, relatively light use of marijuana on kidney function among healthy adults under age 60.
"Our research found no association between current or previous marijuana use and kidney function," said lead investigator Murray Mittleman, professor of Epidemiology at the Harvard T.H. Chan School of Public Health.
"However, our research does not address heavy users, the elderly, or those with pre-existing chronic kidney disease. Research is needed to evaluate the impact of marijuana use in adults 60 and over, and among those with existing or at risk of developing kidney disease," Mittleman said.
Likewise, they did not observe a statistically significant association between the history of marijuana use and the incidence of microalbuminuria, a moderate increase in the level of urine albumin and a marker of kidney disease.
