Criminal justice clients typically need drug 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 admitted into a criminal justice substance abuse rehab center or recovery program. The first step is to determine the criminal justice clients eligibility. This step is accomplished 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 rehabilitation while they are incarcerated. For the best possible 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.
