Research has revealed much about what works and what doesn’t work when it comes to interventions for drug abusing offenders. For example, interventions such as boot camps, intensive supervision, and generic case management have not been proven effective in addressing drug abuse issues. However, treatments that utilize cognitive behavioral therapies, residential treatment, contingency management, and medications have demonstrated effectiveness in reducing drug abuse and criminal behavior. Studies examining other forms of treatment, including drug courts and re-entry programs like Break the Cycle, have demonstrated promise but need more research, as do other interventions, including the Serious Violent Offender Reentry Initiative and Strengths Based Case Management.
