Criminal justice client rehabs are available being a considerably better option than jail time or heavy fines for those who have already been convicted of any sort of alcohol or drug related crime. For example, somebody who has been in prison for driving under the influence of drugs or alcohol may qualify to obtain rehab services for their problem instead of serving time in prison. The judge could even order that the individual receive rehabilitation, either alone or as well as other consequences. New offenders specifically will often be given the ability to go with a criminal justice client rehab as opposed to other sentencing, and it is highly recommended that they benefit from it if it is an alternative. The concept behind criminal justice client rehabs is that it is far more effective and efficient to invest commitment into treatment than enforcement of other consequences. Much research has been done to find out how effective this process is on recidivism rates, i.e. if the criminal justice client returns or not to criminal justice system following rehab. The signs and indicators seem to be quite positive, and criminal justice clients that do experience rehab have a better probability of remaining out of the system following rehab.
