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 admitted into a criminal justice substance abuse 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 determine how much and what type of drug is necessary. Often, the criminal justice clients obtain their drug and alcohol 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.
