Criminal justice client rehabs can be considered as a significantly better option than incarceration or heavy fines for those who have already been convicted of any sort of drug or alcohol related crime. For instance, somebody who has been in prison for dui of drugs or alcohol may qualify for rehab services because of their problem instead of serving time in prison. The judge could even order the individual receive rehabilitation, either alone or as well as other sentencing. New offenders specifically in many cases are given the opportunity to select a criminal justice client rehab as an alternative to other sentencing, and it is highly recommended they make the most of it if it's a choice. The theory behind criminal justice client rehabs is it is much more efficient and effective to invest time and energy into treatment than punishment. Much research has been done to observe how effective this approach is on recidivism rates, i.e. if the criminal justice client returns or not to criminal justice system following rehab. The signs and indicators seem quite positive, and criminal justice clients who take part in rehabilitation have a much better probability of remaining out of the system after treatment.
