Criminal justice clients typically need substance abuse rehabilitation due to problems with drug and alcohol abuse. Due to the nature of the criminal justice system, there are distinct steps and guidelines that must be completed in order to be accepted into a criminal justice substance abuse rehabilitation center or recovery program. The first step is to establish the criminal justice clients eligibility. This step is completed by a panel of officials who decide how much and what type of treatment is necessary. Often, the criminal justice clients obtain their substance abuse treatment while they are incarcerated. For the best possible results, they are encouraged, if not strictly directed, to continue their recovery process once they leave jail and enroll in sober living or a therapeutic community.
