Criminal justice clients frequently need substance abuse treatment due to 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 accepted into a criminal justice drug or alcohol rehabilitation facility or recovery program. The first step is to determine 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 obtain their substance abuse rehabilitation while they are incarcerated. For the best possible results, they are encouraged, if not strictly directed, to continue their recovery process once they leave jail and enroll in sober living or a therapeutic community.
