All-cause mortality and overdose deaths among 4192 people who inject drugs in Stockholm: a 10-year register-based cohort study

All-cause mortality among PWID in Stockholm declined over the study period, alongside significant reductions in opioid overdose deaths, during a period of broadened harm reduction and reduced reporting of opioid injecting drug use. Our findings support continued scale-up of OAT and THN and consideration of supervised consumption sites to further reduce preventable deaths.
