A team of investigators from the University of North Texas School of Public Health, the University of Florida, and Emory University compared changed in the prevalence of monthly opioid-related deaths before and after Colorado retailers began selling cannabis to adults.
They reported: “Colorado’s legalization of recreational cannabis sales and use resulted in a 0.7 deaths per month reduction in opioid-related deaths. This reduction represents a reversal of the upward trend in opioid-related deaths in Colorado.”
Authors concluded, “Legalization of cannabis in Colorado was associated with short-term reductions in opioid-related deaths.”
An abstract of the study, “Recreational cannabis legalization and opioid-related deaths in Colorado, 2000-2015,” appears online here.
