Criminal justice client rehabs can be considered like a considerably better option than incarceration or heavy fines for those who have been convicted of any kind of drug or alcohol related crime. For example, anyone who has been found guilty of driving drunk of alcohol or drugs may be eligible for treatment services because of their problem rather than serving time in jail. The judge may even order that the individual receive rehabilitation, either alone or in addition to other consequences. First time offenders in particular are often given the chance to select a criminal justice client rehab as opposed to other sentencing, and it is well-advised that they make the most of it when it is 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 find out how effective this method is on recidivism rates, i.e. if the individual returns or not to criminal justice system following rehab. All indicators seem to be quite positive, and criminal justice clients that experience treatment have a much better chance of remaining out of the system following treatment.
