Criminal justice client rehabs can be considered like a far better option than time in jail or heavy fines for many who have already been convicted of any type of alcohol or drug related crime. As an example, someone who has been found guilty of driving under the influence of alcohol or drugs may qualify to obtain rehab services for his or her problem rather than serving time in prison. The judge could even order the individual receive rehab, either alone or together with other consequences. First time offenders specifically tend to be given the ability to select a criminal justice client rehab as an alternative to other sentencing, and it is well-advised they reap the benefits of it when it is an alternative. The theory behind criminal justice client rehabs is it is much more effective and efficient to invest time and effort into rehabilitation than enforcement of other consequences. Much research has been done to discover how effective this approach is on recidivism rates, i.e. if the criminal justice client returns or not to criminal justice system following treatment. All indicators appear to be quite positive, and criminal justice clients that experience rehabilitation have a much better possibility of remaining out of the judicial system after rehab.
