Criminal justice clients often need drug rehabilitation due to problems with drug or alcohol addiction. 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 rehab center or recovery program. The initial step is to figure out 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. 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 process once they leave jail and enroll in a sober living home or a therapeutic community.
