Criminal justice client rehabs are available as being a far better option than prison time or significant fines for those who have been convicted of any type of alcohol or drug related crime. As an example, somebody who has been in prison for driving drunk of drugs or alcohol may qualify to get treatment services because of their problem rather than serving time in prison. The judge could even order the individual receive treatment, either alone or along with other sentencing. New offenders in particular tend to be given the ability to choose a criminal justice client rehab rather than other sentencing, and it is highly recommended they make the most of it if it is a choice. The theory behind criminal justice client rehabs is that it is far more efficient and effective to invest effort and time into treatment than punishment. Much research has been done to discover how effective this approach is on recidivism rates, i.e. if the individual returns or not to criminal justice system following rehabilitation. 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 system after treatment.
