The aim of this report is to provide an overview of recent literature on the effectiveness of harm reduction services that address the needs of people who smoke/inhale drugs (these terms are used interchangeably below). The search strategy included international literature, however the focus was on Canadian jurisdictions. We summarize the interventions that have been implemented for this population, any relevant practice or technical guidance and available evidence on impact. This document includes the key messages and highlights that emerged from a Community Opioid/Overdose Capacity Building (COM-CAP) project webinar on safer smoking. This component was completed in collaboration with event speakers, with the goal of reflecting on community-led efforts that may not have been included in other documents. Participants with living and lived experience were compensated for their time and contributions to the webinar and write-up of this document.
