Criminal justice clients often need drug treatment 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 admitted into a criminal justice drug or alcohol rehab center or recovery program. The initial 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 drug is necessary. Sometimes, the criminal justice clients receive their substance abuse rehabilitation 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.
