Criminal justice clients often need substance abuse treatment due to problems with 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 accepted into a criminal justice substance abuse rehab facility or recovery program. The first 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. Often, the criminal justice clients obtain their drug and alcohol treatment while they are incarcerated. For the best possible results, they are encouraged, if not strictly directed, to continue their recovery once they leave jail and enroll in sober living or a therapeutic community.
