Criminal justice client rehabs can be considered as a far better option than time in jail or significant fines for those who have already been convicted of any sort of alcohol or drug related crime. For example, anyone who has been found guilty of driving under the influence of alcohol or drugs may be eligible to get rehabilitation services for their problem as an alternative to serving time in jail. The judge may even order that the individual receive rehabilitation, either alone or as well as other sentencing. New offenders in particular in many cases are given the chance 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 theory behind criminal justice client rehabs is that it is much more efficient and effective to invest time and effort into treatment than enforcement of other consequences. Much research has been carried out to find out how effective this strategy is on recidivism rates, i.e. if the criminal justice client returns or not to criminal justice system following rehab. The signs and indicators seem to be quite positive, and criminal justice clients that experience treatment have a much better possibility of remaining out of the judicial system following rehab.
