Facts? This was published three years ago. Since then, more states have not only allowed medicinal marijuana, but many have allowed legal recreational use of it, yet the opioid crisis has only gotten worse. The junkies overdosing on heroin and black market Fentanyl don't give a shit about your weed, pot head.
There has been a decrease but mostly in the states that are allowing it to be legal. Many still have not made it legal...ohio has medical legal but no dispensaries and no recreational. Opioid overdosing is pretty bad here.
