Criminal justice client rehabs can be considered being a far better option than jail time or significant fines for those who have been convicted of any sort of alcohol or drug related crime. For example, a person who has been found guilty of driving under the influence of alcohol or drugs may qualify to receive rehab services for his or her problem rather than serving time in prison. The judge might order that the individual receive treatment, either alone or along with other sentencing. First time offenders specifically tend to be given the ability to pick a criminal justice client rehab rather than other sentencing, and it is well-advised that they make the most of it if it is a possibility. The theory behind criminal justice client rehabs is it is far more effective and efficient to invest commitment into rehabilitation than enforcement of other consequences. Much research has been done to see how effective this approach is on recidivism rates, i.e. if the criminal justice client returns or not to criminal justice system following rehabilitation. All indicators seem to be quite positive, and criminal justice clients who experience rehab have better potential for remaining out of the judicial system following rehab.
