Criminal justice client rehabs are available as being a considerably better option than jail time or heavy fines for individuals who have already been convicted of any kind of drug or alcohol related crime. For example, someone who has been found guilty of driving while impaired of drugs or alcohol may be eligible for rehabilitation services for their problem instead of serving time in jail. The judge might order the individual receive treatment, either alone or together with other sentencing. Very first time offenders specifically are often given the opportunity select a criminal justice client rehab as an alternative to other sentencing, and it is well-advised they take advantage of it when it is a possibility. The theory behind criminal justice client rehabs is it is way more efficient and effective to invest time and energy into treatment than enforcement of other consequences. Much research has been done to find out how effective this method is on recidivism rates, i.e. if the criminal justice client returns or not to criminal justice system following rehab. The signs and indicators seem to be quite positive, and criminal justice clients that do experience rehabilitation have a better probability of remaining out of the judicial system after treatment.
