Criminal justice clients often need drug or alcohol rehabilitation because of their problems with drug and alcohol abuse. Due to the nature of the criminal justice system, there are distinct steps and guidelines that must be adhered to in order to be admitted into a criminal justice drug or alcohol rehabilitation center or recovery program. The first 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 or alcohol is necessary. Often, the criminal justice clients receive their drug treatment 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.
