Criminal justice client rehabs are available as a considerably better option than incarceration or significant fines for individuals who have already been convicted of any sort of alcohol or drug related crime. For instance, someone who has been in prison for driving while impaired of alcohol or drugs may qualify to obtain rehabilitation services for their problem as opposed to serving time in jail. The judge may even order the individual receive treatment, either alone or as well as other sentencing. Very first time offenders specifically tend to be given the ability to choose a criminal justice client rehab as opposed to other sentencing, and it is well-advised they reap the benefits of it if it's an option. The theory behind criminal justice client rehabs is that it is much more effective and efficient to invest time and effort into rehabilitation than enforcement of other consequences. Much research has been carried out 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 that do experience rehabilitation have a better possibility of remaining out of the judicial system following rehab.
