Criminal justice client rehabs are available as being a considerably 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 found guilty of driving while impaired of drugs or alcohol may qualify to obtain treatment services for his or her problem instead of serving time in prison. The judge may even order that the individual receive treatment, either alone or together with other sentencing. Very first time offenders in particular will often be given the chance to pick a criminal justice client rehab as opposed to other sentencing, and it is well-advised they benefit from it if it is an option. The theory behind criminal justice client rehabs is it is much more effective and efficient to invest effort and time into rehabilitation than enforcement of other consequences. Much research has been done 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 seem to be quite positive, and criminal justice clients that take part in rehab have a better possibility of remaining out of the judicial system after rehabilitation.
