Criminal justice client rehabs are available being a far better option than prison time or significant fines for those who have already been convicted of any kind of alcohol or drug related crime. For example, somebody who has been in prison for dui of drugs or alcohol may qualify to get rehab services for his or her problem as opposed to serving time in prison. The judge may even order the individual receive rehab, either alone or together with other consequences. New offenders in particular in many cases are given the ability to choose a criminal justice client rehab as an alternative to other sentencing, and it is well-advised they reap the benefits of it if it's an option. The theory behind criminal justice client rehabs is that it is far more efficient and effective to invest time and effort into rehab than enforcement of other consequences. Much research has been completed to discover how effective this strategy 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 to be quite positive, and criminal justice clients that do experience treatment have a better probability of remaining out of the system following treatment.
