Criminal justice client rehabs can be considered being a significantly better option than prison time or significant fines for many who have been convicted of any sort of alcohol or drug related crime. By way of example, someone who has been in prison for driving while impaired of drugs or alcohol may qualify to receive rehabilitation services because of their problem as an alternative to serving time in jail. The judge might even order that the individual receive treatment, either alone or together with other sentencing. First-time offenders in particular tend to be given the opportunity to select a criminal justice client rehab as opposed to other sentencing, and it is highly recommended that they make the most of it if it is a possibility. The theory behind criminal justice client rehabs is it is far more efficient and effective to invest time and energy into rehabilitation than enforcement of other consequences. Much research has been carried out to see how effective this process 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 quite positive, and criminal justice clients that experience rehabilitation have a much better potential for remaining out of the judicial system after rehabilitation.
