In recent years, there has been an increased examination of organizational-level innovation adoption in substance abuse treatment organizations. However, the majority of these studies have focused on community-based treatment centers. One understudied area of the substance abuse treatment system is correctional institutions. This study uses the Criminal Justice Drug Abuse Treatment Studies (CJ-DATS) cooperative's National Criminal Justice Treatment Practices (NCJTP) survey to examine the adoption of detoxification services and pharmacotherapies for the treatment of substance abuse across a nationally representative sample of correctional institutions (n=198). There were significant differences between jails and prisons in the percentage of organizations offering detoxification services and medications. Specifically, detoxification services were offered by 5% of prisons and 34% of jails; and, medications were offered by 6% of prisons and 32% of jails. Binary logistic regression models were used to examine the associations between these services and organizational characteristics, including context, resources, previously introduced practices, culture, and systems integration. Variables measuring organizational context and previously introduced practices were significant correlates of the provision of both detoxification services and medications. Multivariate results indicated that the differences between jails and prisons remained significant after controlling for other organizational factors. Although the adoption of detoxification services and pharmacotherapies may be a controversial topic for correctional institutions, these services have the potential to improve offender well-being and reduce public health risks associated with substance abuse.
