As fentanyl overdose crisis hits Americans hard where's proof that 'safe injection sites' work?

President Biden has turned a blind eye to a disturbing twist in the fentanyl crisis. More than 70,000 Americans have been killed yet we don’t track the safe injection site's efficacy.

New York City desperately needs the big picture of what happens to street addicts who come through OnPoint’s doors once they leave.  Howard Husock is the author of "The Poor Side of Town: And Why We Need It" (Encounter Books). He is a senior fellow in domestic policy studies at the American Enterprise Institute. 

Let’s assume that the sites reflect a sincere effort to reduce the wave of drug overdoses that claimed the lives of more than 2,000 New Yorkers last year. But before they expand — including to the entire state of Rhode Island, which has authorized them — we must make sure of something — that they actually work.
