Criminal justice client rehabs are available being a far better option than jail time or significant fines for many who have already been convicted of any kind of drug or alcohol related crime. As an example, someone who has been found guilty of driving while impaired of alcohol or drugs may be eligible for rehabilitation services for his or her problem as opposed to serving time in prison. The judge may even order that the individual receive treatment, either alone or together with other consequences. New offenders in particular tend to be given the ability to choose a criminal justice client rehab as opposed to other sentencing, and it is well-advised that they reap the benefits of it if it is a choice. The theory behind criminal justice client rehabs is that it is much more efficient and effective to invest time and effort into treatment than enforcement of other consequences. Much research has been done to discover how effective this process 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 take part in rehab have a much better possibility of remaining out of the system following rehab.
