Criminal justice client rehabs can be considered as a significantly better option than time in jail or heavy fines for those who have already been convicted of any sort of drug or alcohol related crime. As an example, anyone who has been found guilty of driving under the influence of alcohol or drugs may be eligible to get rehab services because of their problem as opposed to serving time in jail. The judge might order the individual receive treatment, either alone or in addition to other sentencing. New offenders specifically tend to be given the chance to go with a criminal justice client rehab as an alternative to other sentencing, and it is highly recommended they reap the benefits of it when it is a choice. The theory behind criminal justice client rehabs is that it is way more effective and efficient to invest commitment into rehab than enforcement of other consequences. Much research has been carried out to discover how effective this method 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 who do experience rehab have a much better possibility of remaining out of the system following rehabilitation.
