Criminal justice client rehabs can be considered as being a significantly better option than prison time or heavy fines for many who have already been convicted of any sort of drug or alcohol related crime. By way of example, a person who has been in prison for driving under the influence of alcohol or drugs may be eligible to receive rehab services for his or her problem as an alternative to serving time in prison. The judge might order that the individual receive rehabilitation, either alone or together with other sentencing. New offenders specifically are often given the opportunity select a criminal justice client rehab as an alternative to other sentencing, and it is well-advised that they take advantage of it when it is an alternative. The idea behind criminal justice client rehabs is it is far more efficient and effective to invest effort and time 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. All indicators seem to be quite positive, and criminal justice clients that do take part in rehabilitation have a better chance of remaining out of the system following treatment.
