The study found that the drug court was able to reduce reoffending for methamphetamine-involved as well as other types of drug-using offenders. This suggests that the expanded use of drug courts is at least part of the solution to the most recent drug crisis involving methamphetamine abuse. Among DWI offenders, however, drug-court graduation was not related to reduced reoffending compared with non-DWI offenders processed by the hybrid court. The latter finding suggests that newly emerging hybrid DWI/drug courts and their treatment providers should pay attention to the need for drug-specific interventions as well as the need to assess and treat individuals based on their existing level of readiness for treatment. Information was obtained on 87 individuals who had participated in the hybrid drug court between 2001 and 2005. The drug court offenders were compared with a sample of similar offenders (n=124) who were sentenced to prison. The hybrid DWI/drug court accepts both drug offenders and DWI offenders. Substance abuse treatment services were delivered to participants by the local county human services agency under contract with the drug court. 4 tables, 1 figure, 2 notes, and 34 references
