Criminal justice client rehabs are available being a considerably better option than incarceration or significant fines for those who have already been convicted of any kind of drug or alcohol related crime. By way of example, a person who has been in prison for driving under the influence of drugs or alcohol may be eligible to receive treatment services for problem instead of serving time in prison. The judge might order the individual receive treatment, either alone or along with other consequences. New offenders specifically are often given the opportunity to choose a criminal justice client rehab as an alternative to other sentencing, and it is well-advised they take advantage of it when it is an option. The theory behind criminal justice client rehabs is that it is far more efficient and effective to invest effort and time into rehabilitation than punishment. Much research has been carried out to observe how effective this approach is on recidivism rates, i.e. if the individual returns or not to criminal justice system following rehab. All indicators appear to be quite positive, and criminal justice clients who take part in rehabilitation have a much better probability of remaining out of the judicial system following rehabilitation.
