A cautionary tale about medical marijuana and opioid deaths
Washington Post

Five years ago, a study of death certificate data attracted notice for suggesting that states that passed medical marijuana laws saw 25 percent fewer opioid overdose deaths on average than states that barred medical cannabis.

The authors were careful to point out that this finding was only a correlation, an intriguing hint at something that needed further exploration. There was no way to establish whether the availability of medical cannabis in some states protected against overdosing on harder drugs, even if some people used marijuana for pain.
