Researchers are calling for formal clinical trials into the efficacy of marijuana for treating opioid use disorder after a newly published study found that cannabis may ease many common symptoms of opioid withdrawal.
The study, conducted by researchers at the Johns Hopkins University School of Medicine and published in the forthcoming issue of the Journal of Substance Abuse Treatment, asked 200 people with past-month opioid and marijuana use whether their symptoms of opioid withdrawal improved or worsened when they consumed cannabis.
Of the 125 respondents who used marijuana to treat their withdrawal, nearly three-quarters (72 percent) said it eased their symptoms, while only 6.4 percent said it made them worse. Another 20 percent reported mixed results, and three people (2.4 percent) said cannabis didn’t seem to have an obvious effect either way.
At least four states already include opioid use disorder (OUD) as a qualifying condition for medical marijuana, but critics have complained that there’s little evidence to support that policy. In the introduction to their new paper, the researchers acknowledge that “these approvals are concerning because of the limited and conflicting evidence suggesting cannabis can both improve and worsen opioid withdrawal and treatment retention.”
