- What this could lead to
- If successful, this could show that cannabis or non-drug therapies like MIRE or TENS are effective alternatives to opioids for pain relief, potentially reducing opioid use.
- What could go wrong
- This trial has not yet started recruiting, and its design is observational rather than a controlled experiment. Results may not prove which treatment is best, and individual responses to cannabis or opioids can vary widely.
