Criminal justice client rehabs can be considered being a far better option than time in jail or heavy fines for those who have been convicted of any sort of alcohol or drug related crime. As an example, someone who has been in prison for driving under the influence of drugs or alcohol may be eligible for rehabilitation services for problem instead of serving time in prison. The judge might order that the individual receive treatment, either alone or as well as other sentencing. First-time offenders in particular tend to be given the ability to choose a criminal justice client rehab as an alternative to other sentencing, and it is well-advised they make the most of it when it is an alternative. The idea behind criminal justice client rehabs is that it is much more effective and efficient to invest time and energy into rehabilitation than enforcement of other consequences. Much research has been carried out to see how effective this process is on recidivism rates, i.e. if the criminal justice client returns or not to criminal justice system following rehab. The signs and indicators appear to be quite positive, and criminal justice clients who experience treatment have a much better chance of remaining out of the judicial system after treatment.
