I agree (it's meaningless though, I'm just pointing out the obvious above, I'm not an expert here) for acute injury it makes sense to use opioids in severe cases like you mention, however, I think we still need to find the best strains and cultivate them for pain use, we've only scratched the surface with cannabis, it's a big genus. Weed ain't what it used to be.

For chronic cases, I think chronic makes a lot of sense.

Pain helps you get moving. Opioid's don't. Too much pain is debilitating. Surely we can find a formula here (a very very large one).

Cannabis never removes all the pain. I think that's the main feature here.
