Medical cannabis legalization is associated with a decrease in the frequency of nonmedical prescription opioid use, according to a Rutgers study.
The study, published in the International Journal of Mental Health and Addiction, examined data from a nationally representative survey of adults who reported nonmedical prescription opioid use – or using prescription medications without a prescription or in a manner other than prescribed.
According to the study, when states implement medical cannabis laws, there is a 0.5 to 1.5 percentage point decrease in regular to frequent (up to or greater than once per week on average) nonmedical prescription opioid use among people who reported using opioids in the previous year. However, these reductions were concentrated in people who met diagnostic criteria for cannabis addiction.
Still, the pros of legalizing marijuana to address risky opioid use should be considered alongside the cons, according to Hillary Samples, faculty member at the Center for Pharmacoepidemiology and Treatment Science in the Rutgers Institute for Health, Health Care Policy and Aging Research and lead author of the study.
“There might be some benefits to allowing legal access to medical cannabis in the context of opioid-related harms, ”Samples said. “However, from a policy perspective, there are much more effective interventions to address the ongoing overdose crisis, such as increasing access to treatment for opioid addiction.”
According to the Centers for Disease Control and Prevention, the rate of drug overdose deaths rose more than 14 percent from 2020 to 2021 in the United States. To understand approaches to mitigate this crisis, researchers have examined whether cannabis serves as an alternative to opioid use as cannabis might help with pain and symptoms of opioid withdrawal.
