Criminal justice client rehabs can be considered like a far better option than incarceration or heavy fines for those who have been convicted of any type of drug or alcohol related crime. By way of example, a person who has been in prison for driving while impaired of alcohol or drugs may qualify to receive rehabilitation services because of their problem instead of serving time in prison. The judge may even order the individual receive rehab, either alone or in addition to other consequences. First-time offenders in particular tend to be given the opportunity to pick a criminal justice client rehab as opposed to other sentencing, and it is highly recommended that they benefit from it when it is an option. The theory behind criminal justice client rehabs is that it is much more effective and efficient to invest time and energy into treatment than enforcement of other consequences. Much research has been completed to see how effective this approach is on recidivism rates, i.e. if the criminal justice client returns or not to criminal justice system following treatment. The signs and indicators seem to be quite positive, and criminal justice clients that experience rehab have a much better potential for remaining out of the judicial system following rehab.
