Criminal justice clients often need drug or alcohol rehabilitation because of their problems with drug or alcohol addiction. Due to the nature of the criminal justice system, there are specific steps and guidelines that must be completed in order to be accepted into a criminal justice drug rehabilitation program 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 treatment is necessary. Sometimes, the criminal justice clients obtain their substance abuse rehabilitation 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 long-term residential transitional living program.
