Each clean and well-lit booth at Insite comes equipped with a stainless-steel table and a small chair. A large one-way mirror entirely covers one wall, serving two purposes: it helps injection-drug users locate a vein, and it allows medical staff, monitoring clients from the other side, to see if they need additional supplies or are displaying the signs of overdose.

In its fourteen years of operation, Insite, a supervised injection facility (SIF) in Vancouver, British Columbia, has responded to 6,440 overdoses. No one has ever died.

In fact, in nearly thirty years and after millions of doses of heroin, cocaine, and methamphetamine, no safe injection site has ever had an overdose death.
