Fatal and non-fatal opioid overdose risk following release from prison: A retrospective cohort study using linked administrative data

Among individuals who are released from prison, opioid overdose is a leading cause of death with a risk more than ten-fold the general population. Although the epidemiology of opioid-related fatalities has been described, few studies have characterized both fatal and non-fatal opioid-related poisonings. The objective of this study was to estimate risk of fatal and non-fatal opioid overdose among adults released from prison.
