Criminal justice client rehabs can be considered as a significantly better option than prison time or heavy fines for those who have already been convicted of any kind of drug or alcohol related crime. For example, anyone who has been in prison for driving under the influence of drugs or alcohol may qualify to obtain rehabilitation services because of their problem instead of serving time in jail. The judge could even order the individual receive treatment, either alone or together with other sentencing. New offenders specifically tend to be given the ability to pick a criminal justice client rehab rather than other sentencing, and it is well-advised that they benefit from it if it is a possibility. The theory behind criminal justice client rehabs is that it is way more efficient and effective to invest time and energy into treatment than enforcement of other consequences. Much research has been carried out to see how effective this approach 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 experience treatment have better chance of remaining out of the judicial system after rehab.
