Criminal justice client rehabs are available as being a far better option than incarceration or heavy fines for those who have been convicted of any kind of alcohol or drug related crime. As an example, somebody who has been in prison for driving under the influence of drugs or alcohol may be eligible to obtain rehab services for their problem as opposed to serving time in jail. The judge might even order the individual receive rehab, either alone or together with other consequences. New offenders specifically in many cases are given the chance to select a criminal justice client rehab as an alternative to other sentencing, and it is highly recommended that they take advantage of it if it is an option. The theory behind criminal justice client rehabs is it is way more efficient and effective to invest effort and time into rehab than enforcement of other consequences. Much research has been completed to find out how effective this method is on recidivism rates, i.e. if the individual returns or not to criminal justice system following treatment. The signs and indicators appear to be quite positive, and criminal justice clients who do experience treatment have better possibility of remaining out of the system following rehabilitation.
