I have a friend who is a doctor (he appears to lean Conservative, though I'm not 100% sure). I asked him his opinion on the "opioid crisis," and this is what he said (paraphrased):
In the years after ObamaCare passed, but before it went into effect, and before the term "opioid crisis" entered the public lexicon, there was a major push from professional associations, such as the AMA, ASA, ASRA, etc., to address "pain management." Doctors would be forced to sit through Powerpoint presentations on this supposed pain management crisis, and they received all sorts of pamphlets and literature on new guidelines for addressing pain issues. The common perception at the time was that prescription opiate painkillers are drugs with high abuse potential, and doctors were reluctant to prescribe them for fear of trouble with state licensing boards/agencies. However, the professional associations indicated that restrictions on prescription painkiller access would be lifted under the impending ObamaCare regime and new guidelines, and that doctors effectively had a "green light" to prescribe more liberally.
At the same time, many regional industries, such as coal mining, were being stamped out under the weight of federal regulation, and large swaths of the Heartland were suddenly unemployed. The trend of offshoring manufacturing jobs continued at this time as well. As a result, lots of people who were used to doing physical labor suddenly had no jobs, and they also had greater access to prescription painkillers. You can probably guess how it proceeded from there.
Anyway, my doctor friend blames the professional associations and the government for pushing "pain management" so hard, and he thinks it's obnoxious to hear them talk about an "opioid crisis" they basically created. Based on what I know, I tend to agree with him. I also have my own theories about whether it was intentional, but I'll spare you those (for now).
