Criminal justice client rehabs can be considered as being a significantly better option than jail time or significant fines for those who have already been convicted of any sort of drug or alcohol related crime. For instance, a person who has been in prison for driving drunk of drugs or alcohol may be eligible for rehab services for his or her problem instead of serving time in prison. The judge may even order that the individual receive treatment, either alone or as well as other consequences. New offenders in particular are often given the ability to choose a criminal justice client rehab as opposed to other sentencing, and it is highly recommended they benefit from it if it is a possibility. The concept behind criminal justice client rehabs is that it is far more efficient and effective to invest commitment into rehabilitation than enforcement of other consequences. Much research has been carried out to see how effective this method is on recidivism rates, i.e. if the criminal justice client returns or not to criminal justice system following rehab. The signs and indicators appear to be quite positive, and criminal justice clients that do experience treatment have a much better chance of remaining out of the judicial system after treatment.
