NEW YORK — Sitting before a large mirror in a cubicle in East Harlem, a man in his mid-40s tied a length of elastic around his arm and began searching for a vein.
He made no effort to hide his next step: Injecting himself with illicit fentanyl — an often deadly opioid, far more powerful than heroin.
A medical worker watched the man's reflection from a desk in a room set up like a call center — but for the strategically placed mirrors, the neatly stacked sterile syringes and crack pipes, the "crash cart" with oxygen tanks and overdose-reversing medication.
