Criminal justice client rehabs are available being a far better option than time in jail or significant fines for individuals who have already been convicted of any sort of alcohol or drug related crime. For example, someone who has been in prison for driving under the influence of drugs or alcohol may qualify for rehabilitation services because of their problem instead of serving time in prison. The judge might order that the individual receive treatment, either alone or along with other sentencing. New offenders in particular in many cases are given the ability to choose a criminal justice client rehab instead of other sentencing, and it is well-advised they reap the benefits of it if it is a choice. 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 observe how effective this method is on recidivism rates, i.e. if the individual returns or not to criminal justice system following rehab. All indicators seem to be quite positive, and criminal justice clients that do take part in rehabilitation have better probability of remaining out of the system after rehabilitation.
