Criminal justice client rehabs are available being a considerably better option than prison time or heavy fines for individuals who have already been convicted of any sort of alcohol or drug related crime. By way of example, someone who has been in prison for driving under the influence of drugs or alcohol may qualify to get rehabilitation services for their problem instead of serving time in jail. The judge might even order the individual receive treatment, either alone or along with other sentencing. First-time offenders specifically will often be given the opportunity select a criminal justice client rehab rather than other sentencing, and it is highly recommended they make the most of it if it is a possibility. The theory behind criminal justice client rehabs is it is way more efficient and effective to invest commitment into treatment than enforcement of other consequences. Much research has been carried out to find out how effective this method is on recidivism rates, i.e. if the individual returns or not to criminal justice system following rehab. The signs and indicators seem quite positive, and criminal justice clients that experience treatment have a much better potential for remaining out of the system after rehabilitation.
