None were known to exist in the U.S. until the disclosure in a medical journal, although several states and cities are pushing to establish these so-called supervised injection sites where users can shoot up under the care of trained staff who can treat an overdose if necessary.
In the report released Tuesday, two researchers said they've been evaluating an underground safe place that opened in 2014. As a condition of their research, they didn't disclose the location of the facility — which is unsanctioned and potentially illegal — or the social service agency running it.
The researchers offered little data, and their main finding was that no one died while injecting at the safe place. There were two overdoses on site, which were reversed by staff members using the overdose medication naloxone.
Advocates and some politicians in recent years have called for government-sanctioned injection sites as the U.S. grapples with the opioid epidemic. More than 52,000 Americans died from drug overdoses in 2015 — the most ever — fueled by soaring abuse of heroin and prescription painkillers. Government statistics for the first nine months of last year, also released Tuesday, show overdose death rates continuing to spiral.
