Our current healthcare system says, hey, if you're poor/out of work/disabled, here's some cash to buy dangerously addictive opiates that will short-term make you feel better. What could go wrong?
Here's some blog posts arguing the ACA actually increased the severity of the opioid crisis:

I'm (nevertheeless) pro-universal healthcare, but our idea of healthcare should probably not include these drugs in any but the most extreme and limited circumstances (like, I'm lying in a hospital bed). They're too dangerous.
Having doctors actively prescribe them, under incentives from pharma companies to sell them, seems to me predatory in the same way we think of street dealers stalking schoolyards as predatory.
Chris Arnade has done a great job documenting the crises at a personal level. I highly recommend checking out some of his articles and tweetstorms. It's gut-wrenching stuff (and obviously the problem goes way deeper than simple access).
But pharma/doctors/govt pushing drugs isn't helping, and is probably making it much worse.
