Criminal justice clients frequently need substance abuse treatment due to problems with 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 accepted into a criminal justice drug or alcohol treatment center or recovery program. The initial step is to determine 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 drug and alcohol 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.
