This presentation includes findings from both the offender surveys conducted for the MADCE and the 24-month post-enrollment criminal justice records. One focus will be on reporting substance abuse impacts. Using 6- and 18-month follow-up survey data and oral test results, we will report on 1) the trajectory of recovery and 2) whether, and for whom, drug courts work in terms of reducing drug use. The other primary theme will use the survey and administrative records to address 1) whether drug courts impact crime and incarceration, 2) to what extent these effects are durable over time, and 3) whether drug courts are most effective for high- or low-risk offenders.
