Criminal justice client rehabs are available as a considerably better option than incarceration or heavy fines for individuals who have already been convicted of any type of drug or alcohol related crime. As an example, a person who has been in prison for driving drunk of drugs or alcohol may qualify to receive rehabilitation services for their problem as opposed to serving time in jail. The judge might order that the individual receive treatment, either alone or together with other consequences. First time offenders in particular are often given the chance to select a criminal justice client rehab instead of other sentencing, and it is well-advised they make the most of it if it's an option. The theory behind criminal justice client rehabs is it is way more effective and efficient to invest time and effort into treatment than enforcement of other consequences. Much research has been carried out 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 rehab have better possibility of remaining out of the system after rehabilitation.
