Criminal justice client rehabs are available being a far better option than incarceration or heavy fines for individuals who have already been convicted of any sort of alcohol or drug related crime. For example, anyone who has been in prison for driving drunk of alcohol or drugs may qualify to receive rehabilitation services for problem instead of serving time in jail. The judge might order that the individual receive rehab, either alone or together with other sentencing. New offenders specifically will often be given the ability to choose a criminal justice client rehab as an alternative to other sentencing, and it is well-advised they benefit from it when it is a choice. The concept behind criminal justice client rehabs is it is much more effective and efficient to invest time and effort into treatment than enforcement of other consequences. Much research has been done to discover how effective this process is on recidivism rates, i.e. if the criminal justice client returns or not to criminal justice system following treatment. All indicators seem to be quite positive, and criminal justice clients that do experience rehabilitation have a much better chance of remaining out of the judicial system after treatment.
