Understanding Polydrug Use Risk and Protective Factors, Patterns, and Trajectories to Prevent Drug Overdose

This project is a collaboration with King County Public Health to conduct an exploratory sequential mixed methods evaluation of drug use behaviors, patterns, trajectories, and risk factors in a sample of King County, WA residents who initiated use within the past three years of a high-risk drug class. The quantitative and qualitative results from our study will inform development of novel early intervention strategies and development of methods to reach a currently hidden population with overdose prevention programs and related evaluations.
