I wasn't saying they were comparable drugs. I was saying one is overprescribed for pain level that could be managed by something less drastic.
These people would be better off on thc.
Marijuana is a great replacement for those who never started down this path and okay a means of getting off opiates. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6777788/
The linked paper doesn't appear to me to make the claim you did. The combination group (the one from which you could validate the claim you made) is very small - only 486. In fact the paper appears to very carefully outline its own considerable limitations. The authors detail the lack of research in the area and point out a number of conflicting results, including results that directly contradict their own.
That being said, it is a well written, interesting, and thoughtful piece of research. It (and the nearby comment by waheoo) raise quite a few interesting questions for me regarding patient perception and how withdrawal symptoms might interact with marijuana. I also wonder which specific symptoms and underlying conditions might correlate with the various groups. I'm glad you brought this paper to my attention!
I'm sorry but I have to call you out on this. It's complete BS - we simply don't have anything that's remotely comparable to opiates for pain relief.
That being said I'll second that the opiate epidemic in the US is largely the fault of prohibition. Illegality feeds all sorts of negative cycles that wouldn't otherwise exist.
