Criminal justice clients frequently 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 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 or alcohol is necessary. Sometimes, the criminal justice clients obtain their drug rehabilitation while they are incarcerated. For optimum results, they are encouraged, if not strictly directed, to continue their recovery process once they leave jail and enroll in sober living or a long-term residential transitional living program.
