A simpler explanation is there's just a LOT more fentanyl on the streets now then there use to be. And then, it's very potent and easy for users to overdose. It's easy to make the jump from those two factors to a rapid increase in fentanyl addiction and deaths. If you remove one of those two factors then you reduce the increase in addiction and death. So either reduce the amount of fentanyl on the streets or reduce the risk of overdose. I think Narcan being made OTC recently is an attempt at reducing the risk of overdose ending in death at least.
