Criminal justice client rehabs are available as a significantly better option than prison time or heavy fines for those who have already been convicted of any sort of alcohol or drug related crime. By way of example, somebody who has been in prison for driving while impaired of alcohol or drugs may qualify to get treatment services for problem instead of serving time in prison. The judge might even order the individual receive treatment, either alone or together with other consequences. New offenders in particular are often given the ability to select a criminal justice client rehab as opposed to other sentencing, and it is highly recommended they take advantage of it if it's a choice. The concept behind criminal justice client rehabs is that it is far more effective and efficient to invest time and effort into rehab than enforcement of other consequences. Much research has been done to find out 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 quite positive, and criminal justice clients who do experience treatment have a better chance of remaining out of the judicial system following rehabilitation.
