Criminal justice client rehabs can be considered as being a considerably better option than jail time or heavy fines for those who have already been convicted of any kind of alcohol or drug related crime. For example, someone who has been in prison for dui of alcohol or drugs may be eligible to get rehab services for their problem as opposed to serving time in jail. The judge may even order that the individual receive rehabilitation, either alone or in addition to other sentencing. New offenders specifically will often be given the ability to choose a criminal justice client rehab as opposed to other sentencing, and it is well-advised that they take advantage of it if it's a choice. The concept behind criminal justice client rehabs is that it is way more efficient and effective to invest time and effort into rehabilitation than enforcement of other consequences. Much research has been carried out to see how effective this process 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 to be quite positive, and criminal justice clients that take part in rehabilitation have a much better probability of remaining out of the judicial system following rehabilitation.
