Criminal justice client rehabs are available being a far better option than incarceration or heavy fines for individuals who have already been convicted of any sort of alcohol or drug related crime. For instance, somebody who has been in prison for driving drunk of alcohol or drugs may be eligible to receive rehab services for their problem rather than serving time in jail. The judge could even order the individual receive treatment, either alone or in addition to other consequences. New offenders specifically are often given the chance to choose a criminal justice client rehab instead of other sentencing, and it is well-advised they take advantage of it if it is a possibility. The concept behind criminal justice client rehabs is it is far more efficient and effective to invest time and effort into rehabilitation than enforcement of other consequences. Much research has been done to observe how effective this approach is on recidivism rates, i.e. if the criminal justice client returns or not to criminal justice system following treatment. The signs and indicators seem quite positive, and criminal justice clients that do take part in treatment have a better probability of remaining out of the judicial system following rehabilitation.
