Criminal justice client rehabs can be considered as being a considerably better option than jail time or heavy fines for those who have been convicted of any sort of alcohol or drug related crime. For instance, someone who has been in prison for driving under the influence of drugs or alcohol may be eligible to obtain rehab services for his or her problem as an alternative to serving time in jail. The judge could even order the individual receive rehab, either alone or in addition to other consequences. First time offenders specifically tend to be given the chance to go with a criminal justice client rehab as opposed to other sentencing, and it is highly recommended they make the most of it when it is an option. The theory behind criminal justice client rehabs is it is far more efficient and effective to invest time and energy into rehabilitation than enforcement of other consequences. Much research has been carried out to discover how effective this strategy is on recidivism rates, i.e. if the individual returns or not to criminal justice system following rehab. The signs and indicators seem to be quite positive, and criminal justice clients that experience rehab have a better potential for remaining out of the system after rehabilitation.
