Criminal justice clients typically need substance abuse treatment because of their problems with addiction. Due to the nature of the criminal justice system, there are specific steps and guidelines that must be completed in order to be accepted into a criminal justice drug or alcohol treatment 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 decide how much and what type of drug is necessary. Sometimes, the criminal justice clients obtain 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.
