Criminal justice client rehabs are available being a far better option than prison time or significant fines for individuals who have already been convicted of any kind of drug or alcohol related crime. By way of example, a person who has been found guilty of dui of drugs or alcohol may be eligible for rehabilitation services for problem rather than serving time in prison. The judge could even order that the individual receive rehabilitation, either alone or along with other consequences. New offenders specifically in many cases are given the opportunity to pick a criminal justice client rehab instead of other sentencing, and it is highly recommended that they take advantage of it when it is a choice. The theory behind criminal justice client rehabs is that it is much more efficient and effective to invest time and effort into rehab 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 treatment. All indicators seem to be quite positive, and criminal justice clients that take part in treatment have a better chance of remaining out of the judicial system following treatment.
