Criminal justice client rehabs can be considered as a significantly better option than incarceration or significant fines for those who have already been convicted of any type of alcohol or drug related crime. For instance, someone who has been in prison for driving drunk of drugs or alcohol may be eligible to receive rehabilitation services because of their problem as opposed to serving time in prison. The judge may even order that the individual receive rehab, either alone or along with other consequences. New 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 they take advantage of it when it is an option. The theory behind criminal justice client rehabs is it is much more effective and efficient to invest time and effort into treatment than enforcement of other consequences. Much research has been done to observe how effective this approach is on recidivism rates, i.e. if the individual returns or not to criminal justice system following rehab. The signs and indicators seem to be quite positive, and criminal justice clients that do take part in treatment have a better probability of remaining out of the system following rehabilitation.
