Criminal justice client rehabs are available being a significantly better option than time in jail or heavy fines for those who have been convicted of any type of drug or alcohol related crime. By way of example, anyone who has been found guilty of driving while impaired of drugs or alcohol may be eligible to obtain treatment services for his or her problem instead of serving time in prison. The judge may even order the individual receive rehab, either alone or along with other sentencing. First-time offenders specifically tend to be given the opportunity select a criminal justice client rehab rather than other sentencing, and it is well-advised that they reap the benefits of it when it is a possibility. The theory behind criminal justice client rehabs is that it is much more efficient and effective to invest commitment into rehabilitation than enforcement of other consequences. Much research has been done to observe how effective this method is on recidivism rates, i.e. if the criminal justice client returns or not to criminal justice system following rehab. The signs and indicators seem to be quite positive, and criminal justice clients that do take part in rehabilitation have better probability of remaining out of the judicial system following rehabilitation.
