Criminal justice client rehabs can be considered as a considerably better option than jail time or heavy fines for those who have been convicted of any type of alcohol or drug related crime. For example, anyone who has been in prison for dui of alcohol or drugs may be eligible to get rehabilitation services because of their problem instead of serving time in prison. The judge may even order the individual receive rehabilitation, either alone or as well as other sentencing. New offenders specifically in many cases are given the chance 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 theory behind criminal justice client rehabs is it is much more effective and efficient to invest effort and time into rehab than punishment. Much research has been done to find out how effective this approach is on recidivism rates, i.e. if the individual returns or not to criminal justice system following rehab. The signs and indicators seem quite positive, and criminal justice clients that experience rehabilitation have better potential for remaining out of the judicial system after treatment.
