Criminal justice clients often need substance abuse rehabilitation 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 drug or alcohol rehabilitation center or recovery program. The first step is to figure out the criminal justice clients eligibility. This step is accomplished by a panel of officials who decide how much and what type of treatment is necessary. Sometimes, the criminal justice clients obtain their drug and alcohol 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.
