Criminal justice client rehabs are available like a far better option than jail time or significant fines for those who have already been convicted of any kind of alcohol or drug related crime. By way of example, a person who has been in prison for dui of alcohol or drugs may be eligible to get rehabilitation services for their problem as an alternative to serving time in jail. The judge might order that the individual receive rehab, either alone or together with other consequences. New offenders in particular will often be given the chance to go with a criminal justice client rehab instead of other sentencing, and it is highly recommended they reap the benefits of it if it is an alternative. The theory behind criminal justice client rehabs is that 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 treatment. The signs and indicators seem quite positive, and criminal justice clients that experience treatment have a much better possibility of remaining out of the judicial system following rehab.
