Criminal justice client rehabs are available as a considerably better option than incarceration or heavy fines for many who have been convicted of any sort of alcohol or drug related crime. For instance, someone who has been found guilty of driving under the influence of drugs or alcohol may be eligible for rehabilitation services for their problem as an alternative to serving time in prison. The judge may even order the individual receive treatment, either alone or together with other consequences. First time offenders in particular tend to be given the opportunity select 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 a choice. The theory behind criminal justice client rehabs is that it is far more efficient and effective to invest time and effort into treatment than enforcement of other consequences. Much research has been done to find out how effective this approach is on recidivism rates, i.e. if the individual returns or not to criminal justice system following rehabilitation. The signs and indicators seem quite positive, and criminal justice clients that do take part in treatment have a better potential for remaining out of the system after treatment.
