Criminal justice clients frequently need substance abuse treatment due to problems with drug or alcohol 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 rehabilitation center or recovery program. The first step is to figure out the criminal justice clients eligibility. This step is completed by a panel of officials who determine how much and what type of drug or alcohol is necessary. Often, 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 a sober living home or a long-term residential transitional living program.
