Conducted qualitative and quantitative data collection with persons who use opioids in three target counties to assess harm reduction strategies used to lower the risk of opioid overdose and infectious disease transmission; gaps in knowledge about strategies that can lower the risk of opioid overdose and infectious disease transmission; and how the at-risk populations would best receive communications from the Department of Health and other agencies about risk reduction strategies. The second phase of the project focuses on disseminating the evaluation findings to the target counties and to other stakeholder groups.
