Criminal justice client rehabs are available as being a far better option than incarceration or significant fines for those who have already been convicted of any sort of alcohol or drug related crime. For example, a person who has been in prison for driving while impaired of alcohol or drugs may qualify to get treatment services because of their problem as opposed to serving time in jail. The judge may even order that the individual receive rehab, either alone or together with other sentencing. First time offenders specifically tend to be given the ability to go with a criminal justice client rehab rather than other sentencing, and it is highly recommended that they make the most of it when it is a possibility. The idea behind criminal justice client rehabs is it is way more effective and efficient to invest effort and time into rehabilitation than enforcement of other consequences. Much research has been completed to observe how effective this approach 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 take part in treatment have better possibility of remaining out of the judicial system following treatment.
