Criminal justice clients often need substance abuse 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 performed in order to be accepted 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 decide how much and what type of drug or alcohol is necessary. Often, the criminal justice clients receive 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 long-term residential transitional living program.
