Criminal justice clients typically need substance abuse rehabilitation due to problems with drug or alcohol addiction. Due to the nature of the criminal justice system, there are distinct steps and guidelines that must be performed in order to be admitted into a criminal justice drug or alcohol rehab center or recovery program. The first step is to establish the criminal justice clients eligibility. This step is completed by a panel of officials who determine how much and what type of treatment is necessary. Sometimes, the criminal justice clients receive their drug rehabilitation while they are incarcerated. For optimum results, they are encouraged, if not strictly directed, to continue their recovery once they leave jail and enroll in sober living or a long-term residential transitional living program.
