Criminal justice clients typically need drug 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 completed in order to be admitted into a criminal justice substance abuse treatment center or recovery program. The initial 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. Often, the criminal justice clients receive their substance abuse treatment while they are incarcerated. For the best possible results, they are encouraged, if not strictly directed, to continue their recovery process once they leave jail and enroll in sober living or a therapeutic community.
