Criminal justice client rehabs are available as a far better option than prison time or heavy fines for those who have already been convicted of any sort of alcohol or drug related crime. For example, somebody who has been in prison for driving under the influence of drugs or alcohol may qualify to receive rehabilitation services for their problem instead of serving time in prison. The judge could even order the individual receive rehab, either alone or along with other sentencing. New offenders in particular in many cases are given the ability to choose a criminal justice client rehab as opposed to other sentencing, and it is well-advised they make the most of it if it's a choice. The theory behind criminal justice client rehabs is it is much more efficient and effective to invest commitment into rehabilitation than punishment. Much research has been completed to find out how effective this approach is on recidivism rates, i.e. if the individual returns or not to criminal justice system following treatment. All indicators seem to be quite positive, and criminal justice clients that do take part in treatment have better potential for remaining out of the judicial system following treatment.
