Criminal justice client rehabs are available like a significantly better option than incarceration or heavy fines for those who have already been convicted of any sort of drug or alcohol related crime. For instance, anyone who has been in prison for driving drunk of drugs or alcohol may qualify for treatment services for their problem as an alternative to serving time in jail. The judge might even order the individual receive treatment, either alone or together with other sentencing. Very first time offenders specifically are often given the opportunity to select a criminal justice client rehab as opposed to other sentencing, and it is well-advised they benefit from it if it is an option. The theory behind criminal justice client rehabs is it is much more effective and efficient to invest commitment into treatment than enforcement of other consequences. Much research has been carried out to see how effective this method 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 take part in rehabilitation have a better possibility of remaining out of the judicial system after rehab.
