Criminal justice clients often need substance abuse rehabilitation because of their 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 rehab facility or recovery program. The initial 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 treatment 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 once they leave jail and enroll in sober living or a long-term residential transitional living program.
