Criminal justice client rehabs are available as a significantly better option than jail time or heavy fines for many who have been convicted of any kind of alcohol or drug related crime. As an example, a person who has been found guilty of driving drunk of drugs or alcohol may qualify for rehab services for his or her problem as opposed to serving time in prison. The judge might even order that the individual receive rehabilitation, either alone or as well as other sentencing. Very first time offenders specifically tend to be given the opportunity to choose a criminal justice client rehab as an alternative to other sentencing, and it is well-advised that they make the most of it when it is an option. The theory behind criminal justice client rehabs is that it is much more effective and efficient to invest effort and time into treatment than enforcement of other consequences. Much research has been carried out to see how effective this method is on recidivism rates, i.e. if the criminal justice client returns or not to criminal justice system following rehabilitation. The signs and indicators appear to be quite positive, and criminal justice clients who do take part in rehab have better potential for remaining out of the judicial system after rehab.
