Criminal justice client rehabs are available as a considerably better option than prison time or heavy fines for those who have been convicted of any sort of drug or alcohol related crime. As an example, someone who has been in prison for dui of alcohol or drugs may qualify to obtain treatment services for problem rather than serving time in prison. The judge might even order the individual receive treatment, either alone or together with other sentencing. New offenders specifically will often be given the ability to go with a criminal justice client rehab instead of other sentencing, and it is well-advised they take advantage of it when it is an option. The idea behind criminal justice client rehabs is it is way more effective and efficient to invest time and energy into rehabilitation than punishment. Much research has been carried out to discover how effective this method is on recidivism rates, i.e. if the individual returns or not to criminal justice system following rehabilitation. The signs and indicators appear to be quite positive, and criminal justice clients who do experience rehab have better probability of remaining out of the system following rehabilitation.
