The judge might even order the individual receive rehab, either alone or in addition to other sentencing. First time offenders specifically will often be given the chance to go with a criminal justice client rehab as opposed to other sentencing, and it is well-advised they make the most of it when it is a choice. The concept behind criminal justice client rehabs is that it is much more efficient and effective to invest effort and time into rehabilitation than punishment. Much research has been done 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 treatment. The signs and indicators seem to be quite positive, and criminal justice clients who take part in rehab have a much better probability of remaining out of the system after rehab.
