Criminal justice clients frequently need substance abuse treatment because of their problems with addiction. Due to the nature of the criminal justice system, there are specific steps and guidelines that must be performed in order to be accepted into a criminal justice drug or alcohol rehabilitation center or recovery program. The first step is to figure out the criminal justice clients eligibility. This step is completed 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 drug and alcohol treatment while they are incarcerated. For the best possible 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.
