Criminal justice client rehabs are available as being a considerably better option than jail time or significant fines for many who have already been convicted of any type of alcohol or drug related crime. By way of example, somebody who has been in prison for dui of alcohol or drugs may be eligible to receive treatment services for their problem rather than serving time in jail. The judge could even order the individual receive treatment, either alone or as well as other sentencing. New offenders in particular are often given the opportunity to choose a criminal justice client rehab as opposed to other sentencing, and it is well-advised they make the most of it when it is an option. The theory behind criminal justice client rehabs is that it is way more effective and efficient to invest time and effort into rehabilitation than enforcement of other consequences. Much research has been done to observe how effective this process is on recidivism rates, i.e. if the criminal justice client returns or not to criminal justice system following treatment. All indicators appear to be quite positive, and criminal justice clients that experience treatment have better chance of remaining out of the judicial system after treatment.
