Study: Daily Cannabis Use Among Pain Patients Associated with Less Non-Prescription Opioid Use

Generic 26 November 2019 | 0 Comments

Patients suffering from persistent pain conditions who frequently use cannabis are far less likely to use non-prescription opioids, according to longitudinal data published in the journal PLOS One.

A team of investigators from Canada and the United States assessed drug use trends in chronic pain patients over a multi-year period (June 1, 2014 to December 1, 2017).

Authors reported “an independent negative association between frequent cannabis use and frequent illicit opioid use.” Specifically, subjects who consumed cannabis daily “had about 50 percent lower odds of using illicit opioids every day [as] compared to cannabis non-users.”

Investigators did not identify a similarly significant association between occasional cannabis use and daily non-prescription opioid use.

They concluded, “These findings provide longitudinal observational evidence that cannabis may serve as an adjunct to or substitute for illicit opioid use among PWUD (people who use drugs) with chronic pain.”

The findings are consistent with those of prior studies — such as those here, here, and here — which report that pain patients reduce their use of opioids following access to medical cannabis therapy.

Late last week, federal officials affirmed that no funding from the Substance Abuse and Mental Health Services Administration could be spent toward programs that propose the use of medical cannabis for those suffering with opioid dependence issues.
