Criminal justice client rehabs can be considered as being a significantly better option than time in jail or heavy fines for those who have been convicted of any sort of alcohol or drug related crime. As an example, a person who has been found guilty of dui of alcohol or drugs may qualify for rehabilitation services for problem as an alternative to serving time in prison. The judge might even order that the individual receive rehab, either alone or as well as other sentencing. Very first time offenders in particular are often given the chance to select a criminal justice client rehab as opposed to other sentencing, and it is highly recommended that they take advantage of it if it is a choice. The theory behind criminal justice client rehabs is it is far more effective and efficient to invest time and effort into rehabilitation than enforcement of other consequences. Much research has been carried out to find out how effective this strategy is on recidivism rates, i.e. if the criminal justice client returns or not to criminal justice system following treatment. The signs and indicators appear to be quite positive, and criminal justice clients who take part in rehab have a much better chance of remaining out of the system following rehab.
