Marijuana legalization in Colorado led to a “reversal” of opiate overdose deaths in that state, according to new research published in the American Journal of Public Health.
“After Colorado’s legalization of recreational cannabis sale and use, opioid-related deaths decreased more than 6% in the following 2 years,” write authors Melvin D. Livingston, Tracey E. Barnett, Chris Delcher and Alexander C. Wagenaar.
