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 kind of alcohol or drug related crime. For example, somebody who has been in prison for dui of drugs or alcohol may be eligible for rehab services for their problem rather than serving time in prison. The judge might even order that the individual receive treatment, either alone or along with other sentencing. New offenders specifically in many cases are given the opportunity to select a criminal justice client rehab instead of other sentencing, and it is well-advised that they make the most of it if it is a choice. The theory behind criminal justice client rehabs is that it is way more efficient and effective to invest commitment into rehabilitation than punishment. Much research has been carried out 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 rehab. All indicators appear to be quite positive, and criminal justice clients who experience rehabilitation have a better possibility of remaining out of the system after rehabilitation.
