Criminal justice client rehabs are available like a significantly better option than prison time or significant fines for those who have been convicted of any kind of alcohol or drug related crime. As an example, anyone who has been in prison for driving under the influence of alcohol or drugs may be eligible to obtain treatment services because of their problem rather than serving time in jail. The judge might even order the individual receive treatment, either alone or together with other sentencing. New offenders specifically tend to be given the chance 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 it is much more effective and efficient to invest time and effort into treatment than punishment. Much research has been carried out to discover how effective this process is on recidivism rates, i.e. if the individual returns or not to criminal justice system following treatment. All indicators appear to be quite positive, and criminal justice clients who experience treatment have better potential for remaining out of the judicial system after rehabilitation.
