Criminal justice client rehabs are available being a far better option than prison time or significant fines for individuals who have already 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 qualify for treatment services for problem instead of serving time in jail. The judge might order the individual receive rehab, either alone or along with other sentencing. First time offenders in particular in many cases are given the ability to go with a criminal justice client rehab as opposed to other sentencing, and it is well-advised they benefit from it when it is a choice. The theory behind criminal justice client rehabs is it is much more efficient and effective to invest commitment into rehabilitation than enforcement of other consequences. Much research has been carried out to find out how effective this approach 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 much better chance of remaining out of the judicial system following rehabilitation.
