Criminal justice clients frequently need drug or alcohol 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 substance abuse rehabilitation center or recovery program. The initial step is to figure out 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. Sometimes, the criminal justice clients obtain their drug 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.
