Criminal justice client rehabs can be considered as a considerably better option than time in jail or significant fines for those who have already been convicted of any kind of alcohol or drug related crime. As an example, a person who has been found guilty of driving under the influence of drugs or alcohol may qualify to obtain rehab services for problem rather than serving time in jail. The judge might order that the individual receive rehabilitation, either alone or together with other consequences. First time offenders specifically will often be given the opportunity to choose a criminal justice client rehab as opposed to other sentencing, and it is well-advised that 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 rehab than punishment. Much research has been carried out to discover how effective this strategy is on recidivism rates, i.e. if the criminal justice client returns or not to criminal justice system following rehab. The signs and indicators appear to be quite positive, and criminal justice clients that take part in treatment have a much better possibility of remaining out of the system after rehabilitation.
