Criminal justice clients frequently need substance abuse rehabilitation because of their 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 substance abuse rehab facility 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 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 a sober living home or a long-term residential transitional living program.
