Criminal justice client rehabs can be considered as being a far better option than prison time or significant fines for individuals who have been convicted of any type of alcohol or drug related crime. By way of example, somebody who has been in prison for driving under the influence of drugs or alcohol may be eligible to receive rehabilitation services because of their problem as an alternative to serving time in jail. The judge might order that the individual receive rehab, either alone or together with other consequences. New offenders in particular are often given the ability to choose a criminal justice client rehab as opposed to other sentencing, and it is well-advised they take advantage of it when it is an option. The concept behind criminal justice client rehabs is that it is far more effective and efficient to invest effort and time into rehabilitation than enforcement of other consequences. Much research has been done to find out how effective this method is on recidivism rates, i.e. if the criminal justice client returns or not to criminal justice system following rehabilitation. All indicators seem quite positive, and criminal justice clients who do take part in treatment have better possibility of remaining out of the judicial system after rehabilitation.
