Criminal justice client rehabs are available as being a significantly better option than jail time or heavy fines for many who have already been convicted of any sort of alcohol or drug related crime. By way of example, anyone who has been in prison for dui of drugs or alcohol may be eligible to get rehabilitation services because of their problem rather than serving time in jail. The judge may even order the individual receive rehabilitation, either alone or in addition to other sentencing. New offenders in particular will often be given the opportunity to pick a criminal justice client rehab instead of other sentencing, and it is highly recommended they take advantage of it when it is a choice. The idea behind criminal justice client rehabs is it is far more efficient and effective to invest effort and time into rehabilitation than punishment. Much research has been carried out to find out how effective this approach is on recidivism rates, i.e. if the individual returns or not to criminal justice system following rehab. All indicators seem quite positive, and criminal justice clients who experience rehab have a much better chance of remaining out of the judicial system after rehabilitation.
