Criminal justice client rehabs can be considered being a far better option than jail time or significant fines for many who have already been convicted of any type of alcohol or drug related crime. As an example, anyone who has been in prison for driving under the influence of drugs or alcohol may be eligible to receive rehab services because of their problem as an alternative to serving time in prison. The judge could even order the individual receive rehab, either alone or in addition to other sentencing. New offenders in particular are often given the opportunity to choose a criminal justice client rehab instead of other sentencing, and it is highly recommended that they reap the benefits of it if it is a choice. The theory behind criminal justice client rehabs is that it is way more effective and efficient to invest time and energy into rehab than punishment. Much research has been carried out to discover how effective this method is on recidivism rates, i.e. if the individual 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 much better possibility of remaining out of the judicial system following treatment.
