Criminal justice client rehabs are available as a considerably better option than prison time or significant fines for those who have already been convicted of any type of drug or alcohol related crime. As an example, somebody who has been found guilty of driving under the influence of alcohol or drugs may qualify to receive rehab 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 together with other sentencing. Very first time offenders specifically will often be given the chance to choose a criminal justice client rehab as opposed to other sentencing, and it is highly recommended that they take advantage of it when it is a possibility. The concept behind criminal justice client rehabs is that it is much more efficient and effective to invest commitment into rehab than punishment. Much research has been carried out to discover 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 seem to be quite positive, and criminal justice clients that experience treatment have better potential for remaining out of the judicial system after rehab.
