Changes in supervised consumption site use and emergency interventions in Montreal, Canada in the first twelve months of the COVID-19 pandemic: An interrupted time series study.

ABSTRACT:

The COVID-19 pandemic has impacted supervised consumption site (SCS) operations in Montréal, Canada, potentially including changes in SCS visits, on-site emergency interventions, injection of specific drugs, and distribution of harm reduction materials.
