Criminal justice client rehabs are available as being a significantly better option than time in jail or significant fines for individuals who have already been convicted of any sort of alcohol or drug related crime. For instance, someone who has been in prison for driving while impaired of alcohol or drugs may qualify for treatment services for problem instead of serving time in jail. The judge could even order the individual receive rehab, either alone or along with other sentencing. Very first time offenders specifically tend to be given the ability to select a criminal justice client rehab as an alternative to other sentencing, and it is well-advised they make the most of it if it is an alternative. The theory behind criminal justice client rehabs is that it is far more efficient and effective to invest commitment into rehabilitation than enforcement of other consequences. Much research has been done 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 do experience treatment have a better potential for remaining out of the judicial system following treatment.
