Criminal justice client rehabs are available 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, somebody who has been in prison for dui of drugs or alcohol may qualify to get rehab services for his or her problem rather than serving time in jail. The judge might order the individual receive rehabilitation, either alone or along with other sentencing. First time offenders specifically tend to be given the opportunity to select a criminal justice client rehab as an alternative to other sentencing, and it is highly recommended they benefit from it when it is an alternative. The theory behind criminal justice client rehabs is that it is far more effective and efficient to invest time and effort into rehabilitation than punishment. Much research has been carried out to find out how effective this process is on recidivism rates, i.e. if the individual returns or not to criminal justice system following rehabilitation. The signs and indicators seem to be quite positive, and criminal justice clients who do experience rehab have a much better chance of remaining out of the judicial system following rehab.
