Criminal justice client rehabs can be considered like a significantly better option than incarceration or heavy fines for those who have already been convicted of any type of alcohol or drug related crime. As an example, a person who has been found guilty of driving under the influence of alcohol or drugs may be eligible for rehab services for their problem rather than serving time in jail. The judge may even order that the individual receive treatment, either alone or as well as other consequences. First time offenders specifically will often be given the ability to choose 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 far more efficient and effective to invest time and energy into rehab than enforcement of other consequences. Much research has been done to find out how effective this method is on recidivism rates, i.e. if the individual returns or not to criminal justice system following rehabilitation. The signs and indicators seem to be quite positive, and criminal justice clients who do take part in rehabilitation have a much better possibility of remaining out of the judicial system following treatment.
