Criminal justice client rehabs are available as being a far better option than jail time or significant fines for many who have already been convicted of any sort of alcohol or drug related crime. For instance, a person who has been found guilty of driving under the influence of alcohol or drugs may qualify for rehabilitation services for his or her problem as an alternative to serving time in prison. The judge might order the individual receive rehabilitation, either alone or in addition to other consequences. Very first time offenders in particular in many cases are given the opportunity to select a criminal justice client rehab as an alternative to other sentencing, and it is well-advised they benefit from it if it's an alternative. The theory behind criminal justice client rehabs is it is far more effective and efficient to invest time and effort into treatment than enforcement of other consequences. Much research has been done to find out how effective this approach 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 quite positive, and criminal justice clients who experience rehab have a better chance of remaining out of the system following rehabilitation.
