Overdose prevention, supervised consumption sites and episodic Overdose Prevention Services (eOPS) are evidence-based health services that provide a place where people who use drugs can be safely monitored and treated if they overdose.

Trained staff provide supervised consumption of a substance a person brings with them to the site. These sites also provide enhanced harm reduction services including the distribution of naloxone and other harm reduction supplies as well as health care services and referrals for treatment.

Overdose prevention services are also provided on an as-needed basis (called “episodic” or “eOPS”). While these are not permanent overdose prevention sites, staff are able to respond to urgent overdose prevention needs in these locations that have seen increases in overdoses and overdose deaths.
