Criminal justice client rehabs are available as being a significantly better option than incarceration or heavy fines for those who have already been convicted of any type of drug or alcohol related crime. By way of example, someone who has been found guilty of driving while impaired of drugs or alcohol may be eligible to obtain treatment services because of their problem instead of serving time in jail. The judge might order that the individual receive rehabilitation, either alone or in addition to other sentencing. First time offenders specifically will often be given the ability to select a criminal justice client rehab as opposed to other sentencing, and it is highly recommended they make the most of it when it is a possibility. The idea behind criminal justice client rehabs is that it is far more efficient and effective to invest commitment into rehabilitation than punishment. Much research has been carried out to discover how effective this method is on recidivism rates, i.e. if the criminal justice client returns or not to criminal justice system following treatment. The signs and indicators seem to be quite positive, and criminal justice clients that do take part in rehab have a much better chance of remaining out of the judicial system following rehab.
