Criminal justice client rehabs can be considered like a far better option than prison time or significant fines for many who have been convicted of any sort of alcohol or drug related crime. As an example, a person who has been in prison for driving under the influence of alcohol or drugs may be eligible for treatment services for their problem rather than serving time in prison. The judge might even order that the individual receive treatment, either alone or together with other sentencing. New offenders in particular are often given the opportunity to select a criminal justice client rehab instead of other sentencing, and it is highly recommended that they make the most of it if it is an option. The concept behind criminal justice client rehabs is it is far more effective and efficient to invest time and energy into treatment than enforcement of other consequences. Much research has been carried out to find out how effective this process 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 who do experience rehab have a much better chance of remaining out of the system following rehabilitation.
