Criminal justice client rehabs are available as a significantly better option than jail time or heavy fines for individuals who have already been convicted of any kind of alcohol or drug related crime. For example, somebody who has been in prison for driving while impaired of drugs or alcohol may be eligible to obtain rehabilitation services for their problem as an alternative to serving time in prison. The judge might order that the individual receive treatment, either alone or along with other consequences. First time offenders specifically are often given the opportunity choose a criminal justice client rehab instead of other sentencing, and it is well-advised they make the most of it when it is an option. The idea behind criminal justice client rehabs is that it is much more effective and efficient to invest time and energy into rehab than enforcement of other consequences. Much research has been carried out to discover how effective this method is on recidivism rates, i.e. if the criminal justice client returns or not to criminal justice system following rehab. The signs and indicators appear to be quite positive, and criminal justice clients who take part in rehabilitation have a better possibility of remaining out of the judicial system following rehabilitation.
