"In summary, there have been many overdose events within Vancouver's SIF [safe injection facility], although the rate of overdoses is similar to rates observed in SIF in other settings. The majority of these overdoses involved the injection of opiates, and most events were successfully managed within the SIF through the provision of oxygen. It is noteworthy that none of the overdose events occurring at the SIF resulted in a fatality. These findings suggest that SIF can play a role in managing overdoses among IDU [injection drug users] and indicate the potential of SIF to reduce morbidity and mortality associated with illicit drug related overdoses."
