Criminal justice client rehabs can be considered as a far better option than incarceration or significant fines for many who have already been convicted of any sort of drug or alcohol related crime. For instance, someone who has been in prison for dui of alcohol or drugs may qualify to obtain rehabilitation services because of their problem instead of serving time in jail. The judge might even order the individual receive treatment, either alone or together with other sentencing. New offenders in particular are often given the opportunity to select a criminal justice client rehab as an alternative to other sentencing, and it is highly recommended they benefit from it when it is an option. The theory behind criminal justice client rehabs is it is way more effective and efficient to invest time and effort into rehab than enforcement of other consequences. Much research has been carried out to discover how effective this approach is on recidivism rates, i.e. if the individual returns or not to criminal justice system following rehabilitation. The signs and indicators seem quite positive, and criminal justice clients that experience rehab have a much better potential for remaining out of the judicial system following rehab.
