Criminal justice client rehabs can be considered as a far better option than incarceration or significant fines for those who have been convicted of any sort of drug or alcohol related crime. For example, a person who has been in prison for driving drunk of alcohol or drugs may qualify to obtain treatment services because of their problem as an alternative to serving time in prison. The judge could even order that the individual receive rehabilitation, either alone or together with other consequences. New offenders in particular will often be given the chance to go with a criminal justice client rehab as opposed to other sentencing, and it is well-advised that they benefit from 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 rehab than punishment. Much research has been carried out to find out how effective this process is on recidivism rates, i.e. if the individual returns or not to criminal justice system following treatment. The signs and indicators appear to be quite positive, and criminal justice clients who experience treatment have a much better probability of remaining out of the judicial system after rehabilitation.
