Criminal justice client rehabs can be considered as a considerably better option than incarceration or heavy fines for many who have been convicted of any type of drug or alcohol related crime. As an example, someone who has been found guilty of driving drunk of alcohol or drugs may be eligible for rehabilitation services for his or her problem as an alternative to serving time in jail. The judge could even order the individual receive rehab, either alone or together with other consequences. New offenders in particular will often be given the chance to select a criminal justice client rehab rather than other sentencing, and it is highly recommended that they take advantage of it when it is a possibility. The theory behind criminal justice client rehabs is it is much more effective and efficient to invest time and effort into rehabilitation than punishment. Much research has been carried out 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. The signs and indicators seem to be quite positive, and criminal justice clients who do take part in treatment have better probability of remaining out of the judicial system following rehab.
