Predicting Illicit Opiate Drug Overdoses in the City of Surrey Impacts of Opioid use in Neighbourhoods

This study examines the spatial and temporal distribution of the incidence of overdoses and deaths attributable to opioid abuse within the City of Surrey from 2016 to 2018.

There is also a strong association with the time of day when these occurrences take place and the day in the month when social assistance payments are made.
