Criminal justice client rehabs are available as a far better option than incarceration or significant fines for those who have already been convicted of any type of drug or alcohol related crime. By way of example, anyone who has been found guilty of driving under the influence of alcohol or drugs may qualify to obtain rehab services because of their problem instead of serving time in prison. The judge might order that the individual receive rehab, either alone or in addition to other sentencing. New offenders specifically in many cases are given the opportunity to pick a criminal justice client rehab instead of other sentencing, and it is well-advised they make the most of it when it is a choice. The idea behind criminal justice client rehabs is that it is far more effective and efficient to invest time and energy into rehab than punishment. Much research has been carried out to find out how effective this method is on recidivism rates, i.e. if the individual returns or not to criminal justice system following rehabilitation. All indicators appear to be quite positive, and criminal justice clients that do experience rehabilitation have a better chance of remaining out of the judicial system after rehabilitation.
