Criminal justice client rehabs can be considered as a considerably better option than jail time or significant fines for many who have already been convicted of any kind of alcohol or drug related crime. For instance, anyone who has been in prison for driving under the influence of drugs or alcohol may be eligible to get treatment services for his or her problem rather than serving time in prison. The judge may even order the individual receive rehab, either alone or in addition to other sentencing. New offenders specifically are often given the ability to choose a criminal justice client rehab instead of other sentencing, and it is well-advised that they take advantage of it when it is an option. The theory behind criminal justice client rehabs is it is much more efficient and effective to invest time and effort into rehab than punishment. Much research has been carried out to see how effective this method is on recidivism rates, i.e. if the individual returns or not to criminal justice system following rehabilitation. All indicators seem to be quite positive, and criminal justice clients that experience treatment have a better potential for remaining out of the judicial system following treatment.
