Criminal justice client rehabs are available as being a far better option than jail time or heavy fines for individuals who have already been convicted of any kind of alcohol or drug related crime. As an example, a person who has been found guilty of driving under the influence of alcohol or drugs may be eligible to get rehab services for their problem as an alternative to serving time in jail. The judge might order the individual receive rehab, either alone or as well as other sentencing. First time offenders in particular are often given the opportunity to go with 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 theory behind criminal justice client rehabs is it is much more efficient and effective to invest time and effort into treatment than enforcement of other consequences. Much research has been done 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. All indicators seem quite positive, and criminal justice clients that experience rehab have a much better possibility of remaining out of the judicial system following treatment.
