Criminal justice client rehabs are available as a considerably better option than time in jail or significant fines for many who have already been convicted of any kind of alcohol or drug related crime. For instance, somebody who has been in prison for driving drunk of drugs or alcohol may qualify to obtain rehab services for their problem instead of serving time in prison. The judge may even order that the individual receive rehab, either alone or as well as other consequences. First-time offenders in particular will often be given the ability to choose a criminal justice client rehab rather than other sentencing, and it is well-advised they make the most of it when it is an option. The theory behind criminal justice client rehabs is that it is way more effective and efficient to invest effort and time into rehabilitation than enforcement of other consequences. Much research has been carried out to discover how effective this method is on recidivism rates, i.e. if the criminal justice client returns or not to criminal justice system following rehab. All indicators seem to be quite positive, and criminal justice clients that do take part in rehab have a much better potential for remaining out of the judicial system following rehabilitation.
