Also the reason why fentanyl/opioids are such a problem is because of our LEGAL pharma industry pushing drugs for terminally ill cancer patients onto people with chronic pain-- then regulation cracking down on said companies and forcing people to go out into the streets to keep their addiction going.
Here is a music video of Insys (the opioid company that got sued into oblivion) bragging about "titration" which was a sales tactic to increase people's dosages over time.

The "War on Drugs" was not initiated in order to look after the welfare of US citizens. It was to more easily criminalize non-whites and subversives.
The solution is very simple if you approach policy with empathy for the addicts themselves: harm reduction to prevent overdoses ("clean" opioids and distribution of narcan) with free rehab programs funded by taxpayers.
But unfortunately for whatever reason the United States is allergic to empathetic policy, so instead we will just keep going down this road until there is a major shift in public sentiment.
