Criminal justice client rehabs are available like a significantly better option than prison time or heavy fines for those who have already been convicted of any kind of alcohol or drug related crime. By way of example, a person who has been found guilty of dui of alcohol or drugs may be eligible to obtain rehab services for his or her problem instead of serving time in prison. The judge could even order the individual receive rehabilitation, either alone or together with other consequences. New offenders specifically are often given the opportunity choose a criminal justice client rehab as opposed to other sentencing, and it is highly recommended they reap the benefits of it when it is an alternative. 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 done to see how effective this process is on recidivism rates, i.e. if the criminal justice client returns or not to criminal justice system following rehab. All indicators seem to be quite positive, and criminal justice clients who take part in rehab have better probability of remaining out of the system following treatment.
