Criminal justice client rehabs are available being a far better option than jail time or heavy fines for individuals who have been convicted of any sort of drug or alcohol related crime. As an example, anyone who has been found guilty of driving while impaired of drugs or alcohol may qualify to obtain rehabilitation services because of their problem as an alternative to serving time in prison. The judge might even order the individual receive rehab, either alone or together with other consequences. First-time offenders specifically tend to be given the opportunity to choose a criminal justice client rehab instead of other sentencing, and it is highly recommended that they make the most of it when it is a possibility. The theory behind criminal justice client rehabs is that it is far more effective and efficient to invest time and effort into rehabilitation than enforcement of other consequences. Much research has been carried out to discover how effective this process is on recidivism rates, i.e. if the criminal justice client returns or not to criminal justice system following rehab. All indicators seem to be quite positive, and criminal justice clients that do experience rehab have a better potential for remaining out of the system following rehab.
