"Solve itself"? Rubbish. If the big-money dealers and distributors ever start losing so much cash from overdoses that they start to care, they'll just stop cutting with fentanyl until things stabilize. Then they'll start the cycle over again.

(I'm not going to bother with any outrage over the idea that we should let people die just because they choose to or have to use illicit drugs .. I'm inured to the fact that a not-insignificant segment of humanity prefers judgement over empathy.)
