Criminal justice client rehabs can be considered as a considerably better option than incarceration or heavy fines for those who have already been convicted of any type of drug or alcohol related crime. For example, somebody who has been found guilty of dui of alcohol or drugs may be eligible to receive rehabilitation services because of their problem instead of serving time in prison. The judge may even order the individual receive rehab, either alone or as well as other consequences. First time offenders in particular in many cases are given the ability to pick a criminal justice client rehab instead of other sentencing, and it is well-advised they take advantage of it when it is a choice. The theory behind criminal justice client rehabs is it is much more effective and efficient to invest time and energy into treatment than enforcement of other consequences. Much research has been completed to find out how effective this method is on recidivism rates, i.e. if the individual returns or not to criminal justice system following rehab. The signs and indicators seem to be quite positive, and criminal justice clients who take part in treatment have a better potential for remaining out of the system after treatment.
