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