Can somebody give some context on the root cause of the problem - the chronic pain epidemic in US. What caused it, why it is more than in other parts of the world and why so many painkillers? Is it cultural?
Obviously, ceteris paribus, less pain is much better than more pain, and there will probably always be acute and chronic pain for therapeutic innovation to tackle. There's no virtue in the experience of chronic pain. But the evidence strongly suggests that patients are worse off with casual access to powerful opiates, and that these products are packaged and sold irresponsibly.
No legitimate underlying medical phenomenon spurred the uptake in opiates.
