Criminal justice client rehabs are available as a considerably better option than prison time or heavy fines for many who have been convicted of any type of alcohol or drug related crime. As an example, a person who has been in prison for driving drunk of drugs or alcohol may be eligible for rehab services for his or her problem as an alternative to serving time in jail. The judge might even order that the individual receive treatment, either alone or along with other sentencing. First time offenders specifically in many cases are given the chance to select a criminal justice client rehab as opposed to other sentencing, and it is highly recommended that they reap the benefits of it when it is a choice. The theory behind criminal justice client rehabs is that it is far more efficient and effective to invest time and energy into rehabilitation than enforcement of other consequences. Much research has been carried out to see how effective this strategy is on recidivism rates, i.e. if the individual returns or not to criminal justice system following rehabilitation. The signs and indicators appear to be quite positive, and criminal justice clients that do take part in rehabilitation have better possibility of remaining out of the system following rehab.
