Criminal justice client rehabs are available as a significantly better option than time in jail or heavy fines for those who have been convicted of any sort of alcohol or drug related crime. By way of example, somebody who has been found guilty of dui of alcohol or drugs may be eligible to receive rehabilitation services for his or her problem rather than serving time in prison. The judge could even order the individual receive rehab, either alone or as well as other sentencing. First-time offenders specifically in many cases are given the opportunity to choose a criminal justice client rehab rather than other sentencing, and it is well-advised that they reap the benefits of it if it is an option. The concept behind criminal justice client rehabs is it is much more efficient and effective to invest effort and time into rehab than punishment. Much research has been carried out to discover 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 seem to be quite positive, and criminal justice clients that do experience rehab have better chance of remaining out of the judicial system after treatment.
