Criminal justice clients often need drug or alcohol rehabilitation due to 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 accepted into a criminal justice substance abuse rehab 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 decide how much and what type of drug is necessary. Often, the criminal justice clients obtain their drug and alcohol 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.
