In November 2020, Oregon voters approved Measure 110, a ballot initiative that decriminalized possession of small quantities of all drugs and allocated hundreds of millions of dollars annually to health services for people who use drugs. Implementation of Measure 110 is ongoing, but several effects are noticeable in the first two years since the measure passed. Among these are substantial decreases in possession of controlled substances arrests and an infusion of funding into harm reduction services that have not traditionally enjoyed a sustainable funding source. This paper analyzes the provisions of Measure 110, examines its early impacts, successes, and challenges, and outlines lessons that jurisdictions contemplating decriminalizing drug possession in the U.S. and globally should consider.
