Criminal justice client rehabs are available as a far better option than time in jail or significant fines for individuals who have already been convicted of any sort of alcohol or drug related crime. As an example, somebody who has been found guilty of driving under the influence of alcohol or drugs may be eligible for treatment services for their problem rather than serving time in jail. The judge might even order the individual receive rehab, either alone or together with other sentencing. 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 highly recommended that they take advantage of it if it's a choice. The theory behind criminal justice client rehabs is it is way more efficient and effective to invest time and effort into rehabilitation than enforcement of other consequences. Much research has been done to observe how effective this process is on recidivism rates, i.e. if the criminal justice client 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 much better probability of remaining out of the system after rehabilitation.
