Criminal justice client rehabs are available as a far better option than jail time or heavy fines for those who have already been convicted of any sort of alcohol or drug related crime. As an example, anyone who has been in prison for driving drunk of alcohol or drugs may qualify for rehab services for their problem as an alternative to serving time in jail. The judge might even order that the individual receive rehab, either alone or together with other sentencing. First-time offenders specifically will often be given the chance to select a criminal justice client rehab rather than other sentencing, and it is well-advised that they make the most of it when it is a possibility. The concept behind criminal justice client rehabs is that it is far more efficient and effective to invest commitment into treatment than enforcement of other consequences. Much research has been carried out 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. The signs and indicators appear to be quite positive, and criminal justice clients who experience treatment have a better chance of remaining out of the judicial system after rehabilitation.
