Criminal justice client rehabs are available as a significantly better option than time in jail or significant fines for those who have been convicted of any sort of drug or alcohol related crime. For instance, a person who has been found guilty of driving while impaired of drugs or alcohol may qualify for rehabilitation services for his or her problem as opposed to serving time in jail. The judge might even order that the individual receive rehabilitation, either alone or as well as other consequences. New offenders in particular will often be given the opportunity select a criminal justice client rehab as opposed to other sentencing, and it is highly recommended they make the most of it if it is an option. The idea behind criminal justice client rehabs is that it is way more efficient and effective to invest time and energy into rehabilitation than punishment. Much research has been carried out 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 appear to be quite positive, and criminal justice clients who experience rehab have better chance of remaining out of the system after rehabilitation.
