Criminal justice client rehabs can be considered as being a significantly better option than jail time or heavy fines for those who have been convicted of any kind of alcohol or drug related crime. By way of example, somebody who has been in prison for driving drunk of drugs or alcohol may be eligible for treatment services for his or her problem as opposed to serving time in prison. The judge might even order that the individual receive rehab, either alone or in addition to other sentencing. New offenders specifically tend to be given the opportunity to choose a criminal justice client rehab rather than other sentencing, and it is highly recommended they take advantage of it if it is an option. The concept behind criminal justice client rehabs is that it is way more effective and efficient to invest effort and time into rehabilitation than punishment. 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 rehabilitation. All indicators seem to be quite positive, and criminal justice clients who do experience rehab have a better chance of remaining out of the judicial system after treatment.
