Criminal justice client rehabs can be considered as being a considerably better option than prison time or significant fines for those who have been convicted of any kind of alcohol or drug related crime. As an example, someone who has been found guilty of driving under the influence of drugs or alcohol may be eligible for treatment services because of their problem as opposed to serving time in prison. The judge may even order that the individual receive rehab, either alone or together with other sentencing. New offenders specifically tend to be given the chance to go with a criminal justice client rehab as an alternative to other sentencing, and it is well-advised they take advantage of it when it is an option. The idea behind criminal justice client rehabs is that it is much more efficient and effective to invest commitment into rehab than punishment. Much research has been carried out to find out how effective this method is on recidivism rates, i.e. if the criminal justice client returns or not to criminal justice system following treatment. The signs and indicators seem quite positive, and criminal justice clients who do take part in treatment have a better probability of remaining out of the system following rehabilitation.
