Criminal justice client rehabs can be considered as a far better option than incarceration or heavy fines for those who have already been convicted of any sort of drug or alcohol related crime. As an example, anyone who has been found guilty of driving under the influence of drugs or alcohol may be eligible to receive treatment services for his or her problem as opposed to serving time in prison. The judge might even order the individual receive rehab, either alone or as well as other sentencing. New offenders specifically in many cases are given the ability to pick a criminal justice client rehab as opposed to other sentencing, and it is highly recommended they make the most of it if it's a choice. The theory behind criminal justice client rehabs is that it is far more effective and efficient to invest time and energy into treatment than punishment. Much research has been carried out to observe how effective this approach is on recidivism rates, i.e. if the criminal justice client returns or not to criminal justice system following treatment. All indicators seem to be quite positive, and criminal justice clients who take part in rehab have a much better potential for remaining out of the system following treatment.
