Criminal justice client rehabs are available being a far better option than time in jail or heavy fines for individuals who have already been convicted of any sort of drug or alcohol related crime. By way of example, someone who has been in prison for driving while impaired of drugs or alcohol may qualify for rehab services for problem instead of serving time in prison. The judge could even order the individual receive treatment, either alone or together with other consequences. First time offenders in particular are often given the opportunity pick a criminal justice client rehab as opposed to other sentencing, and it is highly recommended they reap the benefits of it when it is an alternative. The theory behind criminal justice client rehabs is it is much more efficient and effective to invest effort and time into rehabilitation than enforcement of other consequences. Much research has been carried out to see how effective this approach 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 quite positive, and criminal justice clients that do take part in treatment have a much better potential for remaining out of the judicial system following rehab.
