Criminal justice client rehabs are available being a significantly better option than time in jail or heavy fines for those who have already been convicted of any type of drug or alcohol related crime. By way of example, someone who has been found guilty of dui of drugs or alcohol may qualify to get rehabilitation services for his or her problem instead of serving time in prison. The judge could even order that the individual receive treatment, either alone or together with other sentencing. New offenders in particular are often given the opportunity to choose a criminal justice client rehab rather than other sentencing, and it is highly recommended that they take advantage of it if it is an option. The idea behind criminal justice client rehabs is it is way more efficient and effective to invest effort and time into treatment than enforcement of other consequences. Much research has been carried out to observe how effective this method is on recidivism rates, i.e. if the criminal justice client returns or not to criminal justice system following rehab. All indicators appear to be quite positive, and criminal justice clients who take part in treatment have a much better probability of remaining out of the judicial system following rehab.
