Criminal justice client rehabs are available as being a far better option than jail time or significant fines for those who have already been convicted of any kind of alcohol or drug related crime. As an example, anyone who has been in prison for driving under the influence of drugs or alcohol may qualify to receive rehab services for his or her problem as an alternative to serving time in prison. The judge may even order that the individual receive rehabilitation, either alone or together with other consequences. Very first time offenders in particular tend to be given the opportunity to select a criminal justice client rehab as an alternative to other sentencing, and it is well-advised that they take advantage of it if it is a choice. The concept behind criminal justice client rehabs is that it is far more efficient and effective to invest time and energy into treatment than enforcement of other consequences. Much research has been carried out 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 seem to be quite positive, and criminal justice clients that experience rehabilitation have a much better potential for remaining out of the judicial system after rehabilitation.
