Criminal justice clients frequently need drug or alcohol treatment 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 performed in order to be admitted into a criminal justice substance abuse rehab facility or recovery program. The initial 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 is necessary. Often, the criminal justice clients obtain their drug rehabilitation 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.
