* Supervised-consumption services are known to be effective in reducing drug-related harms, and several dedicated services now exist in Canada.
* It is now time to move from asking whether such services are effective to asking whether, how and under what conditions their benefits can be maximized.
* Integrated and co-located health service models — effectively “one-stop shops” — could improve health outcomes for people who inject drugs by combining the prevention of immediate drug-related harms with access to primary care, mental health care and social service programs.
