Judicial sanctions are used by drug courts to encourage clients to comply with program requirements. However, few studies have explored the application of sanctions in drug courts or the relationship between sanctions and drug court graduation. This article reports the results of a study of sanctions as applied in a drug court in southwest Washington State. Results reveal no significant difference in the number of sanctions accrued between drug court graduates and noncompleters. However, noncompleters are significantly more likely than graduates to accrue sanctions within the first 30 days of entering drug court. Furthermore, accrual of an early sanction is highly predictive of eventual program failure. Severity of the first sanction (regardless of when it was received) is also related to a lower probability of graduation. The authors conclude that information about how offenders accrue sanctions may be useful to drug court personnel as they monitor clients and determine appropriate intervention strategies.
