Criminal justice client rehabs are available as being a significantly better option than prison time or significant fines for those who have already been convicted of any sort of alcohol or drug related crime. By way of example, anyone who has been in prison for driving while impaired of drugs or alcohol may be eligible for rehabilitation services for problem rather than serving time in jail. The judge may even order that the individual receive treatment, either alone or as well as other sentencing. First time offenders specifically tend to be given the opportunity go with a criminal justice client rehab as opposed to other sentencing, and it is highly recommended that they make the most of it when it is an alternative. The idea behind criminal justice client rehabs is that it is much more efficient and effective to invest time and effort into rehabilitation than enforcement of other consequences. Much research has been done to discover 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 appear to be quite positive, and criminal justice clients that do experience treatment have a much better probability of remaining out of the judicial system following rehab.
