They had a point. Vancouver, which has long battled the addiction crisis, opened a safe-injection site nearly 15 years ago. And there have been other pop-ups in other Canadian cities. The evidence is clear: These save lives (no one has died in a safe-injection site, anywhere in the world, ever) and usher more into treatment, while not increasing crime or drug use. Montreal opened three in June. Toronto had long ago embraced other harm-reduction methods, such as expanded access to Naloxone. And the city has 47 needle exchanges, where Philly has one.
