Criminal justice client rehabs are available like a considerably better option than jail time or heavy fines for many who have been convicted of any kind of drug or alcohol related crime. For example, someone who has been found guilty of driving under the influence of alcohol or drugs may be eligible to receive rehabilitation services for problem instead of serving time in jail. The judge may even order that the individual receive rehabilitation, either alone or as well as other sentencing. Very first time offenders specifically will often be given the opportunity to pick a criminal justice client rehab instead of other sentencing, and it is highly recommended they take advantage of it when it is an option. The concept behind criminal justice client rehabs is it is far more efficient and effective to invest time and effort into treatment than enforcement of other consequences. Much research has been carried out 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 rehabilitation.
