Criminal justice client rehabs are available like a considerably better option than incarceration or heavy fines for those who have been convicted of any kind of alcohol or drug related crime. For example, a person who has been in prison for driving drunk of alcohol or drugs may qualify to obtain rehab services for problem as an alternative to serving time in prison. The judge may even order that the individual receive rehab, either alone or together with other consequences. First time offenders in particular will often be given the opportunity to choose a criminal justice client rehab as opposed to other sentencing, and it is highly recommended they take advantage of it when it is an alternative. The concept behind criminal justice client rehabs is that it is way more effective and efficient to invest commitment into rehabilitation than punishment. Much research has been carried out to find out how effective this process is on recidivism rates, i.e. if the criminal justice client returns or not to criminal justice system following rehabilitation. The signs and indicators seem to be quite positive, and criminal justice clients that experience rehabilitation have better potential for remaining out of the judicial system following treatment.
