Criminal justice clients often need substance abuse treatment due to problems with addiction. Due to the nature of the criminal justice system, there are distinct steps and guidelines that must be completed in order to be accepted into a criminal justice substance abuse rehab program or recovery program. The initial step is to determine 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 drug and alcohol 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.
