Criminal justice client rehabs are available as a significantly better option than prison time or heavy fines for those who have already been convicted of any type of alcohol or drug related crime. By way of example, anyone who has been in prison for driving while impaired of drugs or alcohol may be eligible to get rehab services for his or her problem rather than serving time in jail. The judge might order the individual receive rehab, either alone or in addition to other consequences. New offenders specifically in many cases are given the opportunity select a criminal justice client rehab as opposed to other sentencing, and it is well-advised that they reap the benefits of it if it's an option. The theory behind criminal justice client rehabs is that it is way more effective and efficient to invest time and energy into rehabilitation than enforcement of other consequences. Much research has been carried out to observe how effective this method is on recidivism rates, i.e. if the criminal justice client returns or not to criminal justice system following rehabilitation. The signs and indicators seem to be quite positive, and criminal justice clients who experience rehab have a much better chance of remaining out of the judicial system following rehabilitation.
