Substance abuse is a major risk factor for intimate partner violence (IPV). We investigate how a key supply-side intervention – the abuse-deterrent reformulation of a widely-diverted opioid, OxyContin – affected IPV. Our results indicate counties with greater baseline rates of prescription opioid usage experienced relatively larger declines in IPV after OxyContin’s reformulation. The reformulation reduced IPV only in states with smaller illicit drug markets, while states with larger illicit drug markets experienced increased heroin-involved IPV due to substitution towards illicit opioids. Our results underscore the importance of identifying populations at high risk of substitution to illicit opioids and moderating this risk with evidence-based policies.
