Criminal justice clients frequently need substance abuse treatment 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 completed in order to be admitted into a criminal justice substance abuse treatment program or recovery program. The initial step is to determine 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 substance abuse rehabilitation while they are incarcerated. For optimum results, they are encouraged, if not strictly directed, to continue their recovery once they leave jail and enroll in sober living or a long-term residential transitional living program.
