Criminal justice client rehabs can be considered as a significantly better option than jail time or heavy fines for those who have already been convicted of any sort of alcohol or drug related crime. For instance, anyone who has been found guilty of driving under the influence of alcohol or drugs may qualify to receive rehabilitation services for problem as opposed to serving time in jail. The judge might even order that the individual receive rehabilitation, either alone or along with other sentencing. First time offenders specifically are often given the opportunity pick a criminal justice client rehab as opposed to other sentencing, and it is highly recommended they make the most of it if it is a choice. 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 completed to see 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 chance of remaining out of the system following rehabilitation.
