Criminal justice clients frequently 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 accepted into a criminal justice drug or alcohol rehabilitation facility or recovery program. The first step is to establish the criminal justice clients eligibility. This step is accomplished by a panel of officials who decide how much and what type of drug or alcohol is necessary. Often, the criminal justice clients receive their substance abuse rehabilitation while they are incarcerated. For optimum 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.
