Ignored inequities: Critical analysis of the pre-launch development of British Columbia's "Stop Overdose" campaign.

Background: Substance use stigma has been positioned as a major driver of drug toxicity mortality. In response, governmental and public health organizations across Canada have invested significant resources into mass media campaigns that target stigma. Many of these campaigns feature images or stories about people who use drugs (PWUD).

Community-Engaged Research Ethics Training (CERET): developing accessible and relevant research ethics training for community-based participatory research with people with lived and living experience using illicit drugs and harm reduction workers.

Background: Community-based participatory research (CBPR) can directly involve non-academic community members in the research process. Existing resources for research ethics training can be inaccessible to team members without an academic background and do not attend to the full spectrum of ethical issues that arise through community-engaged research practices. We detail an approach to capacity building and training in research ethics in the context of CBPR with people who use(d) illicit drugs and harm reduction workers in Vancouver's Downtown Eastside neighborhood.

Research 101: A process for developing local guidelines for ethical research in heavily researched communities.

Background: Marginalized communities often attract more than their share of research. Too often, this research benefits researchers disproportionately and leaves such communities feeling exploited, misrepresented, and exhausted. The Downtown Eastside (DTES) neighborhood of Vancouver, Canada, has been the site of multiple public health epidemics related to injection drug use as well as the site of much community-led resistance and struggle that has led to the development of cutting-edge harm reduction interventions (e.
