Criminal justice clients typically need substance abuse rehabilitation due to 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 substance abuse rehab center or recovery program. The first step is to determine the criminal justice clients eligibility. This step is accomplished by a panel of officials who determine how much and what type of drug is necessary. Sometimes, the criminal justice clients receive their drug rehabilitation while they are incarcerated. For the best possible results, they are encouraged, if not strictly directed, to continue their recovery once they leave jail and enroll in sober living or a therapeutic community.
