Criminal justice client rehabs are available as being a considerably better option than incarceration or heavy fines for those who have already been convicted of any type of alcohol or drug related crime. For example, someone who has been in prison for driving under the influence of drugs or alcohol may qualify to receive rehabilitation services for problem as an alternative to serving time in prison. The judge might even order the individual receive treatment, either alone or together with other consequences. New offenders specifically are often given the opportunity to go with a criminal justice client rehab rather than other sentencing, and it is highly recommended that they reap the benefits of it when it is a possibility. The theory behind criminal justice client rehabs is it is far more efficient and effective to invest time and energy into treatment than punishment. Much research has been completed to find out how effective this process is on recidivism rates, i.e. if the criminal justice client returns or not to criminal justice system following rehabilitation. All indicators seem to be quite positive, and criminal justice clients who take part in rehabilitation have a better potential for remaining out of the judicial system after rehab.
