Criminal justice client rehabs can be considered being a significantly better option than incarceration or heavy fines for many who have already been convicted of any type of drug or alcohol related crime. As an example, a person who has been found guilty of driving while impaired of alcohol or drugs may be eligible to obtain rehabilitation services because of their problem as an alternative to serving time in prison. The judge may even order that the individual receive rehabilitation, either alone or as well as other sentencing. First time offenders in particular are often given the ability to pick a criminal justice client rehab as an alternative to other sentencing, and it is highly recommended they take advantage of it when it is an option. The theory behind criminal justice client rehabs is it is much more efficient and effective to invest commitment into treatment than enforcement of other consequences. Much research has been carried out to find out how effective this method is on recidivism rates, i.e. if the individual returns or not to criminal justice system following rehabilitation. All indicators seem to be quite positive, and criminal justice clients who experience rehab have a much better probability of remaining out of the judicial system following rehabilitation.
