Criminal justice client rehabs can be considered as being a considerably better option than jail time or significant 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 alcohol or drugs may qualify to obtain treatment services for his or her problem as opposed to serving time in jail. The judge might even order that the individual receive treatment, either alone or along with other sentencing. New offenders specifically in many cases are given the opportunity to select a criminal justice client rehab as opposed to other sentencing, and it is well-advised they take advantage of it when it is a choice. The theory behind criminal justice client rehabs is it is way more efficient and effective to invest time and effort into rehab than punishment. Much research has been carried out to see how effective this process is on recidivism rates, i.e. if the individual returns or not to criminal justice system following rehabilitation. All indicators seem to be quite positive, and criminal justice clients that experience rehabilitation have a better potential for remaining out of the system after treatment.
