Criminal justice client rehabs can be considered like a significantly 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, a person who has been found guilty of driving drunk of drugs or alcohol may qualify for rehabilitation services for his or her problem rather than serving time in prison. The judge might order that the individual receive treatment, either alone or together with other sentencing. Very first time offenders specifically will often be given the chance to go with a criminal justice client rehab as opposed to other sentencing, and it is well-advised that they make the most of it when it is a possibility. The theory behind criminal justice client rehabs is that it is far more efficient and effective to invest time and effort into treatment than enforcement of other consequences. Much research has been completed to find out how effective this method is on recidivism rates, i.e. if the individual returns or not to criminal justice system following rehab. All indicators appear to be quite positive, and criminal justice clients that do experience rehabilitation have a better chance of remaining out of the judicial system after rehabilitation.
