Criminal justice client rehabs are available being a considerably better option than jail time or significant fines for many who have already been convicted of any type of alcohol or drug related crime. As an example, someone who has been in prison for dui of drugs or alcohol may qualify for rehabilitation services for their problem instead of serving time in jail. The judge could even order that the individual receive treatment, either alone or as well as other consequences. Very first time offenders specifically in many cases are given the chance to select a criminal justice client rehab instead of other sentencing, and it is well-advised they make the most of it if it is a possibility. The theory behind criminal justice client rehabs is that it is much more efficient and effective to invest effort and time into treatment than punishment. Much research has been carried out to discover 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 take part in rehab have a much better chance of remaining out of the judicial system after treatment.
