Criminal justice client rehabs are available like a considerably better option than jail time or heavy fines for individuals who have been convicted of any sort of alcohol or drug related crime. By way of example, a person who has been in prison for driving under the influence of alcohol or drugs may qualify for rehab services for his or her problem rather than serving time in jail. The judge might order that the individual receive treatment, either alone or along with other consequences. New offenders in particular in many cases are given the ability to select a criminal justice client rehab instead of other sentencing, and it is well-advised that they take advantage of it when it is an option. The theory behind criminal justice client rehabs is it is much 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 approach is on recidivism rates, i.e. if the criminal justice client returns or not to criminal justice system following rehabilitation. All indicators seem to be quite positive, and criminal justice clients that do experience treatment have a better possibility of remaining out of the judicial system following rehabilitation.
