Criminal justice client rehabs are available as being a far better option than jail time or significant fines for many who have already been convicted of any sort of alcohol or drug related crime. For example, a person who has been found guilty of dui of drugs or alcohol may be eligible to obtain rehabilitation services for problem as an alternative to serving time in prison. The judge might order that the individual receive rehabilitation, either alone or as well as other consequences. First time offenders specifically in many cases are given the chance to choose a criminal justice client rehab as an alternative to other sentencing, and it is highly recommended they take advantage of it when it is an option. The theory behind criminal justice client rehabs is that it is much more efficient and effective to invest effort and time into treatment than punishment. Much research has been carried out to find out 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 appear to be quite positive, and criminal justice clients that experience rehabilitation have a better potential for remaining out of the system after rehabilitation.
