Criminal justice client rehabs can be considered being a significantly better option than time in jail or heavy fines for individuals 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 under the influence of drugs or alcohol may be eligible to receive treatment services for problem instead of serving time in jail. The judge may even order the individual receive rehab, either alone or in addition to other sentencing. First time offenders in particular are often given the ability to select a criminal justice client rehab as opposed to other sentencing, and it is well-advised they make the most of it if it is an option. The theory behind criminal justice client rehabs is it is much more efficient and effective to invest time and effort into treatment than enforcement of other consequences. Much research has been done to observe how effective this strategy is on recidivism rates, i.e. if the individual returns or not to criminal justice system following rehabilitation. The signs and indicators appear to be quite positive, and criminal justice clients who take part in rehabilitation have a much better potential for remaining out of the judicial system after rehabilitation.
