Criminal justice client rehabs are available as a significantly better option than time in jail or significant fines for individuals who have already been convicted of any type of drug or alcohol related crime. As an example, somebody who has been found guilty of driving while impaired of alcohol or drugs may qualify to obtain rehab services for his or her problem rather than serving time in prison. The judge might even order the individual receive treatment, either alone or in addition to other sentencing. New offenders specifically are often given the chance to choose a criminal justice client rehab as opposed to other sentencing, and it is well-advised they make the most of it if it's a choice. The concept behind criminal justice client rehabs is that it is far more effective and efficient to invest time and effort into treatment than punishment. Much research has been carried out to find out how effective this approach is on recidivism rates, i.e. if the criminal justice client returns or not to criminal justice system following rehabilitation. The signs and indicators seem quite positive, and criminal justice clients who do take part in rehab have a much better potential for remaining out of the system after rehabilitation.
