Criminal justice client rehabs are available as a considerably better option than jail time or significant fines for many who have already been convicted of any type of drug or alcohol related crime. By way of example, somebody who has been in prison for driving under the influence of alcohol or drugs may be eligible to obtain rehab services for their problem rather than serving time in prison. The judge might even order that the individual receive treatment, either alone or in addition to other consequences. First-time offenders in particular will often be given the ability to go with a criminal justice client rehab rather than other sentencing, and it is well-advised that they make the most of it when it is a possibility. The concept behind criminal justice client rehabs is that it is far more effective and efficient 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 experience rehab have a better chance of remaining out of the judicial system after treatment.
