Criminal justice client rehabs can be considered as a far better option than jail time or heavy fines for those who have already been convicted of any type of drug or alcohol related crime. As an example, anyone who has been found guilty of driving drunk of alcohol or drugs may be eligible for rehabilitation services for their problem instead of serving time in prison. The judge may even order that the individual receive rehabilitation, either alone or as well as other sentencing. New offenders in particular tend to be given the chance to select a criminal justice client rehab as opposed to other sentencing, and it is well-advised they make the most of it if it is an alternative. The concept behind criminal justice client rehabs is that it is far more efficient and effective to invest time and energy into rehab than enforcement of other consequences. Much research has been carried out to find out how effective this approach is on recidivism rates, i.e. if the criminal justice client returns or not to criminal justice system following rehabilitation. The signs and indicators appear to be quite positive, and criminal justice clients that experience rehab have better probability of remaining out of the judicial system following rehab.
