Criminal justice client rehabs can be considered as being a considerably better option than time in jail or heavy fines for those who have already been convicted of any type of alcohol or drug related crime. For example, anyone who has been in prison for driving drunk of alcohol or drugs may be eligible for rehabilitation services because of their problem instead of serving time in jail. The judge might even order that the individual receive rehab, either alone or together with other consequences. First-time offenders specifically tend to be given the chance to select a criminal justice client rehab rather than other sentencing, and it is well-advised they benefit from it if it is a choice. The concept behind criminal justice client rehabs is that it is much more efficient and effective to invest effort and time into rehabilitation than enforcement of other consequences. Much research has been carried out to find out how effective this method is on recidivism rates, i.e. if the individual returns or not to criminal justice system following rehab. All indicators appear to be quite positive, and criminal justice clients that do take part in rehab have better possibility of remaining out of the system after rehabilitation.
