Criminal justice clients often need drug treatment because of their problems with drug or alcohol addiction. Due to the nature of the criminal justice system, there are distinct steps and guidelines that must be performed in order to be accepted into a criminal justice drug or alcohol rehab program or recovery program. The initial step is to establish the criminal justice clients eligibility. This step is accomplished by a panel of officials who decide how much and what type of treatment is necessary. Often, the criminal justice clients receive their substance abuse treatment while they are incarcerated. For optimum 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.
