States that legalized marijuana may be linked to lower opioid deaths but far more studies need to be done to confirm it, said the director of the National Institutes of Health.
NIH Director Francis Collins said there has been a “statistical relationship” between states that legalized marijuana and lower opioid deaths.
An October study in the American Journal of Public Health found legalization of marijuana in Colorado resulted in a short-term reduction of opioid deaths from 2000 to 2015.
Colorado legalized marijuana back in 2012.
Sen. Bill Cassidy, R-La., asked Collins about the role of marijuana in combating opioid addiction.
