Criminal justice clients frequently need substance abuse rehabilitation because of their problems with drug and alcohol abuse. Due to the nature of the criminal justice system, there are specific steps and guidelines that must be adhered to in order to be accepted into a criminal justice drug or alcohol rehab program or recovery program. The first step is to figure out the criminal justice clients eligibility. This step is completed by a panel of officials who decide how much and what type of drug or alcohol is necessary. Sometimes, the criminal justice clients receive their substance abuse 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 therapeutic community.
