If the US wanted to end the fentanyl and xylazine and nitazene epidemic, it would legalize the controlled manufacture, sale, and usage of the drugs being adulterated. This won't happen, because the 50-year-old War on Drugs is a load-bearing pillar of the US government.
I live in Seattle, decriminalizing drugs didn't turn out that way here.
It's like if Canada wanted to end gun smuggling and school shootings, it would legalize the controlled manufacture, sale, and usage of the guns being banned. But they won't.
I mean, prohibition works while legalization just makes more people use whatever you legalize and increases the negative externalities of its use. You see that almost universally (alcohol, drugs, sex work). The exception is it gets rid of the black markets and some (but not all) of the violence associated with them.
So if the goal is to put cartels out of business then yea, full legalization would help. If the goal is to stop overdoses and addiction then absolutely not.
Xylazine and fentanyl are already legally distributed in the US. I believe Xylazine is still unscheduled.
