Cannabis Plus Opioids in Chronic Pain: Not a Great Combo

Previous research by Humphreys and colleagues showed that people who used medical cannabis also had higher rates of opioid use and misuse. “This is one of many examples where claims about the benefits of medical cannabis are not supported by evidence,” Humphreys told MedPage Today.  The current study had several limitations: it relied on cross-sectional, self-reported data and was subject to possible selection bias and confounding. It also did not assess the frequency or quantity of cannabis or opioid use, or the type of chronic pain.
