Criminal justice clients often need substance abuse treatment because of their problems with drug or alcohol addiction. Due to the nature of the criminal justice system, there are specific steps and guidelines that must be performed in order to be admitted into a criminal justice drug rehabilitation center or recovery program. The first step is to establish the criminal justice clients eligibility. This step is completed by a panel of officials who determine how much and what type of drug is necessary. Sometimes, the criminal justice clients obtain their drug and alcohol treatment 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 therapeutic community.
