Criminal justice clients frequently need substance abuse rehabilitation because of their problems with drug and alcohol abuse. 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 drug or alcohol treatment facility or recovery program. The initial step is to establish the criminal justice clients eligibility. This step is completed by a panel of officials who determine how much and what type of drug or alcohol is necessary. Sometimes, the criminal justice clients receive their drug 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 sober living or a long-term residential transitional living program.
