Key Findings:  This meta-analysis concludes that the current pre-clinical and clinical studies available overall support that cannabis can improve the effect of opioids and also reduce the amount of opioids needed in the treatment of acute pain. Further studies are needed to evaluate dosing and specific populations that would likely benefit the most from the addition of cannabis therapies for pain relief.
