Criminal justice client rehabs are available as being a considerably better option than incarceration or heavy fines for those who have been convicted of any kind of drug or alcohol related crime. As an example, anyone who has been in prison for driving under the influence of alcohol or drugs may qualify to receive treatment services for their problem instead of serving time in jail. The judge may even order that the individual receive treatment, either alone or along with other consequences. First-time offenders specifically will often be given the ability to pick a criminal justice client rehab instead of other sentencing, and it is highly recommended they take advantage of it if it's an alternative. The theory behind criminal justice client rehabs is that it is far more effective and efficient to invest time and effort into treatment than enforcement of other consequences. Much research has been completed to observe how effective this strategy is on recidivism rates, i.e. if the individual returns or not to criminal justice system following rehabilitation. The signs and indicators seem to be quite positive, and criminal justice clients that do experience rehabilitation have a better chance of remaining out of the system following rehab.
