High times and troubled relationships: Recreational marijuana laws and intimate partner violence

This study explores the relationship between Recreational Marijuana Laws (RMLs) and intimate partner violence (IPV). While marijuana is often considered harmless, the existing medical literature reveals both positive and negative impacts of its active ingredient on brain function. Utilizing a difference-in-difference methodology spanning 2006–2016 across 39 states, we find that RMLs produce a 20 percent increase in IPV incidents per 100,000 individuals, which appears to be mediated through mental health issues and binge drinking. These findings highlight the likely need for preventive and proactive policies to address the complex interplay of marijuana, RMLs, and IPV.
