Criminal justice client rehabs can be considered like a significantly better option than time in jail or heavy fines for those who have already been convicted of any kind of alcohol or drug related crime. For example, someone who has been in prison for driving while impaired of drugs or alcohol may qualify to get rehab services because of their problem as opposed to serving time in jail. The judge could even order that the individual receive rehabilitation, either alone or in addition to other consequences. New offenders specifically tend to be given the opportunity to go with a criminal justice client rehab as an alternative to other sentencing, and it is well-advised they reap the benefits of it if it is a choice. The concept behind criminal justice client rehabs is it is way more effective and efficient to invest time and effort into treatment than enforcement of other consequences. Much research has been carried out to discover how effective this strategy 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 take part in rehab have a much better chance of remaining out of the judicial system following rehabilitation.
