October 5, 2017 | Addiction Policy Forum
New research from the National Institute on Drug Abuse (NIDA) and Columbia University suggests that individuals who use marijuana may be more likely than nonusers to misuse prescription opioids and eventually develop an opioid use disorder.
Individuals who reported using marijuana within the past year were 2.6 times more likely than non-users to initiate prescription opioid misuse, defined as “using a drug without a prescription, in higher doses, for longer periods, or for other reasons than prescribed[1}” and were 2.2 times more likely to meet DSM-V diagnostic criteria for opioid use disorder.
