Criminal justice client rehabs are available as a considerably better option than prison time or heavy fines for those who have already been convicted of any type of alcohol or drug related crime. As an example, anyone who has been found guilty of driving while impaired of drugs or alcohol may be eligible for rehabilitation services for his or her problem as opposed to serving time in prison. The judge might order the individual receive treatment, either alone or together with other sentencing. First-time offenders specifically tend to be given the ability to choose a criminal justice client rehab instead of other sentencing, and it is well-advised that they reap the benefits of it when it is a possibility. The idea behind criminal justice client rehabs is that it is way more efficient and effective to invest time and effort into treatment than punishment. Much research has been carried out to discover how effective this process is on recidivism rates, i.e. if the individual returns or not to criminal justice system following treatment. The signs and indicators appear to be quite positive, and criminal justice clients that experience treatment have better chance of remaining out of the judicial system after rehabilitation.
