Criminal justice client rehabs are available as being a significantly better option than time in jail or heavy fines for many who have already been convicted of any type of alcohol or drug related crime. For instance, somebody who has been in prison for driving while impaired of alcohol or drugs may be eligible for rehab services for his or her problem as an alternative to serving time in prison. The judge might order the individual receive treatment, either alone or along with other consequences. First-time offenders specifically are often given the opportunity to choose a criminal justice client rehab rather than other sentencing, and it is highly recommended that they reap the benefits of it when it is a choice. The concept behind criminal justice client rehabs is that it is much more efficient and effective to invest effort and time into rehabilitation than enforcement of other consequences. Much research has been completed to observe how effective this approach is on recidivism rates, i.e. if the criminal justice client returns or not to criminal justice system following rehabilitation. The signs and indicators seem to be quite positive, and criminal justice clients that do experience rehab have a much better probability of remaining out of the system following rehab.
