There are definitely laws of unintended consequences.
Yes, the pharmaceutical industry made fortunes killing people with opioids. Eric Eyre wrote a really good book about this called Death in Mudlick. It doesn't paint the current WV governor in a good light.
But once the supply of drugs that at least people knew the strength and purity of were greatly reduced, the void in the supply was filled by cartels and fentanyl of unknown purity and strength.

It's a difficult problem to solve. Addicts get their drugs. Addiction is a strong motivator.
My oldest son is 28. He grew up from grade 1-9 in Morgantown. I just saw him this past weekend and I asked him who he kept in touch with. So many of these kids from the neighborhood and from school are dead. Overdoses and suicides. Some were from poor families. Some were from well to do families.
It still shocks and upsets me when people my age die. But for teenagers and those in their 20s deal with it so regularly it is tragic.
A reduction in overdose deaths is great news. Regardless of your political team, this is an issue where the "we", meaning the USA, have to win.
