Criminal justice client rehabs are available as being a far better option than prison time or significant fines for those who have been convicted of any sort of alcohol or drug related crime. By way of example, someone who has been in prison for driving while impaired of drugs or alcohol may qualify to get rehab services for their problem instead of serving time in prison. The judge could even order that the individual receive treatment, either alone or as well as other sentencing. First time offenders in particular are often given the opportunity to choose a criminal justice client rehab as opposed to other sentencing, and it is highly recommended they benefit from it if it is a possibility. The idea behind criminal justice client rehabs is it is way more effective and efficient to invest time and effort into treatment than enforcement of other consequences. Much research has been done 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 rehab. All indicators appear to be quite positive, and criminal justice clients who do take part in rehabilitation have better potential for remaining out of the judicial system following rehabilitation.
