Criminal justice client rehabs are available as a far better option than time in jail or significant fines for those who have already been convicted of any type of drug or alcohol related crime. As an example, someone who has been found guilty of dui of alcohol or drugs may be eligible to obtain treatment services for his or her problem instead of serving time in jail. The judge might even order the individual receive treatment, either alone or together with other consequences. New offenders specifically will often be given the opportunity select a criminal justice client rehab as opposed to other sentencing, and it is well-advised they benefit from it if it is an option. The theory behind criminal justice client rehabs is it is way more efficient and effective to invest time and effort into rehabilitation than enforcement of other consequences. Much research has been carried out to see how effective this approach is on recidivism rates, i.e. if the criminal justice client returns or not to criminal justice system following rehab. All indicators seem to be quite positive, and criminal justice clients that experience treatment have a better possibility of remaining out of the system following rehab.
