Criminal justice client rehabs are available as a far better option than incarceration or significant fines for individuals who have already been convicted of any type of alcohol or drug related crime. As an example, anyone who has been in prison for driving under the influence of alcohol or drugs may be eligible for treatment services for his or her problem as an alternative to serving time in jail. The judge might order the individual receive rehab, either alone or together with other sentencing. Very first time offenders specifically in many cases are given the ability to select a criminal justice client rehab as an alternative to other sentencing, and it is highly recommended that they benefit from it if it's an option. The concept behind criminal justice client rehabs is it is much more efficient and effective to invest time and energy into rehab than enforcement of other consequences. Much research has been done to discover how effective this approach is on recidivism rates, i.e. if the criminal justice client returns or not to criminal justice system following rehab. The signs and indicators seem to be quite positive, and criminal justice clients who do experience rehabilitation have a much better chance of remaining out of the system after rehabilitation.
