Criminal justice client rehabs are available as a far better option than incarceration or heavy fines for those who have already been convicted of any kind of alcohol or drug related crime. For instance, a person who has been found guilty of driving under the influence of alcohol or drugs may qualify to receive treatment services for their problem instead of serving time in prison. The judge might even order the individual receive rehab, either alone or along with other consequences. New offenders specifically in many cases are given the chance to choose 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 an option. The theory behind criminal justice client rehabs is that it is much more efficient and effective to invest time and effort into rehabilitation than punishment. Much research has been done to see how effective this approach is on recidivism rates, i.e. if the individual returns or not to criminal justice system following rehabilitation. All indicators seem to be quite positive, and criminal justice clients that take part in rehabilitation have a better chance of remaining out of the system after rehab.
