Criminal justice client rehabs can be considered as being a considerably better option than incarceration or significant fines for individuals who have already been convicted of any sort of drug or alcohol related crime. For example, a person who has been in prison for driving under the influence of alcohol or drugs may qualify to receive rehab services because of their problem rather than serving time in prison. The judge could even order that the individual receive rehabilitation, either alone or together with other consequences. New offenders in particular in many cases are given the ability to pick a criminal justice client rehab as an alternative to other sentencing, and it is well-advised they make the most of it when it is an option. The theory behind criminal justice client rehabs is that it is way more effective and efficient to invest effort and time into rehabilitation than enforcement of other consequences. Much research has been done to discover how effective this approach is on recidivism rates, i.e. if the criminal justice client returns or not to criminal justice system following rehabilitation. All indicators appear to be quite positive, and criminal justice clients who experience rehab have a much better chance of remaining out of the judicial system following rehab.
