Criminal justice client rehabs are available like a considerably better option than time in jail or significant fines for those who have already been convicted of any kind of alcohol or drug related crime. As an example, someone who has been in prison for dui of alcohol or drugs may be eligible to obtain treatment services for problem instead of serving time in prison. The judge might order that the individual receive rehabilitation, either alone or in addition to other consequences. New offenders specifically are often given the opportunity to select a criminal justice client rehab as opposed to other sentencing, and it is well-advised they make the most of it if it is a possibility. The concept behind criminal justice client rehabs is it is far more effective and efficient to invest effort and time into rehab than enforcement of other consequences. Much research has been carried out to find out how effective this method is on recidivism rates, i.e. if the criminal justice client returns or not to criminal justice system following rehabilitation. All indicators seem to be quite positive, and criminal justice clients who do take part in rehab have better possibility of remaining out of the judicial system following treatment.
