Criminal justice client rehabs can be considered being a significantly better option than incarceration or significant fines for individuals who have already been convicted of any sort 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 qualify to obtain treatment services because of their problem instead of serving time in prison. The judge could even order the individual receive rehab, either alone or together with other sentencing. Very first time offenders in particular tend to be given the ability to select a criminal justice client rehab as an alternative to other sentencing, and it is highly recommended they reap the benefits of it if it is a possibility. The idea behind criminal justice client rehabs is it is far more efficient and effective to invest effort and time into rehabilitation than punishment. Much research has been carried out to find out 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 quite positive, and criminal justice clients who do take part in treatment have a much better possibility of remaining out of the judicial system after rehab.
