Criminal justice clients typically need drug or alcohol rehabilitation because of their problems with drug or alcohol addiction. Due to the nature of the criminal justice system, there are specific steps and guidelines that must be adhered to in order to be admitted into a criminal justice substance abuse rehab program or recovery program. The initial step is to establish the criminal justice clients eligibility. This step is accomplished 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.
