Criminal justice client rehabs are available as being a far better option than incarceration or significant fines for many who have already been convicted of any type of drug or alcohol related crime. For instance, a person who has been in prison for dui of alcohol or drugs may be eligible for treatment services because of their problem rather than serving time in jail. The judge might order the individual receive rehab, either alone or in addition to other sentencing. New offenders specifically tend to be given the opportunity to go with a criminal justice client rehab as an alternative to other sentencing, and it is highly recommended they take advantage of it if it is an alternative. The theory behind criminal justice client rehabs is that it is way more effective and efficient to invest time and effort into rehabilitation than enforcement of other consequences. Much research has been done to observe how effective this strategy 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 take part in treatment have a much better potential for remaining out of the system following treatment.
