Criminal justice client rehabs can be considered like a considerably better option than time in jail or heavy fines for those who have been convicted of any kind of drug or alcohol related crime. For instance, someone who has been found guilty of driving while impaired of alcohol or drugs may qualify to receive rehab services for problem instead of 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 opportunity select a criminal justice client rehab instead of other sentencing, and it is highly recommended they reap the benefits of it when it is an option. The theory behind criminal justice client rehabs is that it is way more effective and efficient to invest effort and time into rehab than enforcement of other consequences. Much research has been done to observe how effective this approach is on recidivism rates, i.e. if the criminal justice client returns or not to criminal justice system following rehab. The signs and indicators appear to be quite positive, and criminal justice clients that experience rehabilitation have a much better potential for remaining out of the judicial system after rehabilitation.
