Criminal justice clients frequently need drug 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 adhered to in order to be admitted into a criminal justice substance abuse treatment center or recovery program. The initial 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 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 process once they leave jail and enroll in sober living or a long-term residential transitional living program.
