Using data from 2010 to 2015, the analysis counted 3.7 million fewer daily doses of opioids prescribed in states that allow weed dispensaries, while states that allow only home cultivation saw a decrease of 1.8 million daily prescribed doses.
As the opioid crisis rages on across North America, a number of recent studies are pointing to cannabis and prescription heroin as viable options in curbing the consumption of lethal street opiates, reducing long-term medical and policing costs and extending the lives of users.
In the second study, University of Georgia researchers evaluated the association between the enactment of medical cannabis access laws and opioid prescribing trends among those eligible for Medicare Part D prescription drug coverage.

One of those research projects at McMaster University has looked into how cannabis can be used as an "exit drug" for nearly 1,400 opioid users.
