Fighting Crime by Treating the Offender

Courts designed to stop crime by treating substance use disorders and other problems underlying criminal conduct are known as problem-solving courts. These courts are guided by research substantially driven by NIJ, which managed two seminal studies. We continue to examine new models, strengthen components, and collaborate on recommendations for practice.
