Criminal justice clients typically need substance abuse 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 adhered to in order to be admitted into a criminal justice substance abuse treatment 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 determine how much and what type of drug is necessary. Sometimes, the criminal justice clients obtain their substance abuse treatment 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 a sober living home or a long-term residential transitional living program.
