Criminal justice client rehabs are available as being a considerably better option than time in jail or significant fines for those who have been convicted of any kind of drug or alcohol related crime. By way of example, someone who has been in prison for dui of drugs or alcohol may qualify to obtain rehabilitation services for his or her problem as an alternative to serving time in jail. The judge might order the individual receive rehab, either alone or as well as other sentencing. New offenders in particular tend to be given the opportunity to pick a criminal justice client rehab as opposed to other sentencing, and it is highly recommended they take advantage of it if it's an option. The theory behind criminal justice client rehabs is it is much more efficient and effective to invest time and effort into rehabilitation than enforcement of other consequences. Much research has been carried out to observe how effective this process is on recidivism rates, i.e. if the individual returns or not to criminal justice system following rehab. The signs and indicators seem quite positive, and criminal justice clients that do take part in treatment have better chance of remaining out of the judicial system after rehabilitation.
