Criminal justice client rehabs can be considered being a significantly 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, anyone who has been in prison for dui of drugs or alcohol may qualify to obtain rehabilitation services for his or her problem as opposed to serving time in jail. The judge could even order the individual receive treatment, either alone or along with other sentencing. New offenders specifically in many cases are given the chance to choose a criminal justice client rehab instead of other sentencing, and it is highly recommended they make the most of it when it is an alternative. The theory behind criminal justice client rehabs is it is way more effective and efficient to invest effort and time into treatment than enforcement of other consequences. Much research has been completed to see 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 appear to be quite positive, and criminal justice clients who experience rehabilitation have a better possibility of remaining out of the system after treatment.
