Criminal justice client rehabs are available as a far better option than time in jail or significant fines for those who have been convicted of any kind of drug or alcohol related crime. For example, a person who has been in prison for driving under the influence of drugs or alcohol may qualify to obtain 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 consequences. New offenders specifically in many cases are given the chance to pick a criminal justice client rehab as opposed to other sentencing, and it is well-advised they benefit from it if it's an option. The concept behind criminal justice client rehabs is it is much more effective and efficient to invest time and effort into rehab than punishment. Much research has been carried out to find out how effective this strategy is on recidivism rates, i.e. if the criminal justice client returns or not to criminal justice system following treatment. All indicators seem to be quite positive, and criminal justice clients who do take part in rehab have better chance of remaining out of the judicial system following rehab.
