Implications of prescription drug monitoring and medical cannabis legislation on opioid overdose mortality

Ecological study estimating opioid-related mortality in states with and without a prescription drug monitoring program (PDMP) and/or medical cannabis legislation. The relationship between PDMPs with mandatory access provisions, medical cannabis legislation, and opioid-related mortality rates. When combined with the availability of medical cannabis as an alternative analgesic therapy, PDMPs may be more effective at decreasing opioid-related mortality.
