Criminal justice clients often need substance abuse rehabilitation due to problems with drug and alcohol abuse. Due to the nature of the criminal justice system, there are specific steps and guidelines that must be completed in order to be accepted into a criminal justice drug rehab center or recovery program. The initial 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 obtain their drug 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.
