Painkiller deaths drop by 25% in states with legalized medical marijuana
A study put out by the Journal of the American Medical Association in 2014 made an interesting discovery. In every state that had legalized medical marijuana between 1999 and 2010 (13 states in all), there was a 25% reduction in deaths related to the overdose of legally prescribed opioids. “The difference is quite striking,” said study co-author Colleen Barry, a health policy researcher at Johns Hopkins Bloomberg School of Public Health in Baltimore. She notes that the trend became visible in every state a year after the pot was legalized.
