Criminal justice client rehabs can be considered as a far better option than incarceration or significant fines for those who have been convicted of any type of drug or alcohol related crime. For example, a person who has been in prison for driving drunk of alcohol or drugs may qualify to receive treatment services for his or her problem instead of serving time in jail. The judge might order that the individual receive rehab, either alone or in addition to other sentencing. New offenders specifically will often be given the ability to choose a criminal justice client rehab as opposed to other sentencing, and it is well-advised they benefit from it when it is a choice. The theory behind criminal justice client rehabs is that it is much more efficient and effective to invest time and energy into treatment than punishment. Much research has been done to observe how effective this strategy is on recidivism rates, i.e. if the individual returns or not to criminal justice system following rehab. All indicators seem quite positive, and criminal justice clients who do experience rehab have a better potential for remaining out of the judicial system after rehab.
