The PROMPT Pilot Study is a feasibility mixed methods prospective cohort study following principles of community-based participatory action research. The study recruited 80 people who use drugs and followed them for 6 months while providing access to counselling, nicotine replacement therapy and peer-support in a community setting. A notable reduction in average cigarette use per day (20.5 to 9.3) and illicit substance use (18.8%) was observed at study-end. PROMPT's patient engagement model is an effective harm-reduction strategy for the growing opioid use crisis and can improve the health outcomes of marginalised at-risk populations worldwide.
