Criminal justice client rehabs are available as being a far better option than time in jail or significant fines for those who have already been convicted of any kind of alcohol or drug related crime. As an example, a person who has been found guilty of dui of drugs or alcohol may qualify to receive rehab services for their problem rather than serving time in prison. The judge may even order the individual receive rehabilitation, either alone or together with other sentencing. First time offenders specifically will often be given the opportunity select a criminal justice client rehab as opposed to other sentencing, and it is well-advised that they reap the benefits of it if it is a choice. The theory behind criminal justice client rehabs is that it is much 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. All indicators appear to be quite positive, and criminal justice clients that do take part in rehab have a much better possibility of remaining out of the judicial system following rehabilitation.
