Criminal justice client rehabs can be considered like a significantly better option than jail time or heavy fines for many who have been convicted of any type of drug or alcohol related crime. As an example, a person who has been in prison for driving under the influence of alcohol or drugs may qualify to receive 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 sentencing. New offenders in particular in many cases are given the opportunity to go with a criminal justice client rehab rather than other sentencing, and it is well-advised that they benefit from it when it is an option. The concept behind criminal justice client rehabs is it is far more effective and efficient to invest time and effort into treatment than enforcement of other consequences. Much research has been done to see how effective this method is on recidivism rates, i.e. if the individual returns or not to criminal justice system following rehab. All indicators seem quite positive, and criminal justice clients who do take part in rehab have a much better chance of remaining out of the judicial system after treatment.
