Criminal justice client rehabs are available being a significantly better option than time in jail or heavy fines for those who have already been convicted of any type of alcohol or drug related crime. As an example, a person who has been in prison for driving under the influence of drugs or alcohol may be eligible for rehabilitation services for his or her problem as opposed to serving time in prison. The judge may even order that the individual receive rehabilitation, either alone or in addition to other consequences. First-time offenders specifically are often given the chance to pick a criminal justice client rehab as an alternative to other sentencing, and it is highly recommended that they make the most of it if it is a possibility. The concept behind criminal justice client rehabs is it is way more efficient and effective to invest time and effort 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 rehab. All indicators seem to be quite positive, and criminal justice clients that do take part in rehabilitation have better chance of remaining out of the judicial system after rehab.
