For example, someone who has been in prison for dui of drugs or alcohol may be eligible to obtain treatment services for his or her problem instead of serving time in prison. The judge might even order the individual receive rehabilitation, either alone or together with other consequences. First time offenders specifically in many cases are given the opportunity select a criminal justice client rehab instead of other sentencing, and it is well-advised that they make the most of it if it is a choice. The theory behind criminal justice client rehabs is it is way more efficient and effective to invest commitment into rehab than enforcement of other consequences. Much research has been completed to find out 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 better chance of remaining out of the system following rehab.
