Criminal justice client rehabs are available as a considerably better option than time in jail or significant fines for those who have been convicted of any sort of alcohol or drug related crime. For example, anyone who has been in prison for driving under the influence of alcohol or drugs may qualify to obtain treatment services for problem rather than serving time in prison. The judge might even order that the individual receive rehab, either alone or along with other sentencing. First time offenders specifically will often be given the opportunity to choose a criminal justice client rehab instead of other sentencing, and it is highly recommended they take advantage of it if it is a possibility. The idea behind criminal justice client rehabs is it is much more effective and efficient to invest effort and time into rehab than enforcement of other consequences. Much research has been done 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 rehabilitation. All indicators seem quite positive, and criminal justice clients who experience rehabilitation have a much better potential for remaining out of the judicial system following rehab.
