Criminal justice client rehabs are available being a far better option than prison time or heavy fines for individuals who have already been convicted of any type of alcohol or drug related crime. By way of example, a person who has been in prison for driving drunk of drugs or alcohol may qualify to receive rehabilitation services because of their problem rather than serving time in prison. The judge might order the individual receive treatment, either alone or together with other sentencing. Very first time offenders specifically in many cases are given the chance to choose a criminal justice client rehab instead of other sentencing, and it is highly recommended they benefit from it when it is an option. 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 find out how effective this process 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 who take part in rehabilitation have a better potential for remaining out of the system following rehab.
