Criminal justice client rehabs can be considered as being a significantly better option than incarceration or significant fines for individuals who have already been convicted of any type of alcohol or drug related crime. For instance, a person who has been in prison for driving under the influence of alcohol or drugs may qualify to get rehab services for problem rather than serving time in prison. The judge might order that the individual receive rehab, either alone or together with other sentencing. New offenders specifically will often be given the opportunity to select a criminal justice client rehab rather than other sentencing, and it is highly recommended that they take advantage of it if it is a possibility. The concept behind criminal justice client rehabs is that it is way more efficient and effective to invest time and energy into rehab than enforcement of other consequences. Much research has been carried out to discover how effective this process is on recidivism rates, i.e. if the criminal justice client returns or not to criminal justice system following rehabilitation. All indicators appear to be quite positive, and criminal justice clients who do experience rehabilitation have better potential for remaining out of the system after rehab.
