Criminal justice client rehabs can be considered as being a far better option than prison time or significant fines for those who have already been convicted of any type of alcohol or drug related crime. For instance, a person who has been found guilty of driving under the influence of alcohol or drugs may be eligible to receive rehabilitation services for his or her problem as an alternative to serving time in jail. The judge might even order the individual receive rehabilitation, either alone or as well as other consequences. New offenders specifically in many cases are given the opportunity to choose a criminal justice client rehab as opposed to other sentencing, and it is highly recommended that they reap the benefits of it if it is an alternative. The theory behind criminal justice client rehabs is that it is far more efficient and effective to invest effort and time into rehabilitation than enforcement of other consequences. Much research has been completed to observe 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 who experience treatment have better probability of remaining out of the judicial system after treatment.
