Criminal justice client rehabs can be considered as a considerably better option than time in jail or heavy fines for many who have already been convicted of any type of drug or alcohol related crime. For example, somebody who has been found guilty of driving under the influence of alcohol or drugs may qualify to receive treatment services for problem rather than serving time in jail. The judge might order the individual receive rehabilitation, either alone or in addition to other sentencing. First time offenders specifically tend to be given the opportunity to go with a criminal justice client rehab instead of other sentencing, and it is well-advised that they make the most of it when it is a choice. The theory behind criminal justice client rehabs is it is way more efficient and effective to invest time and effort into treatment than enforcement of other consequences. Much research has been carried out to see how effective this strategy 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 do experience rehab have better possibility of remaining out of the system after rehabilitation.
