Criminal justice client rehabs are available being a significantly better option than jail time or heavy fines for those who have been convicted of any kind of drug or alcohol related crime. For instance, somebody who has been in prison for driving while impaired of alcohol or drugs may be eligible to get rehabilitation services for his or her problem as opposed to serving time in prison. The judge might even order that the individual receive rehab, either alone or together with other sentencing. Very first time offenders specifically tend to be given the ability to choose a criminal justice client rehab as an alternative to other sentencing, and it is well-advised that they take advantage of it when it is a choice. The theory behind criminal justice client rehabs is it is way more efficient and effective to invest effort and time into rehabilitation 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 individual returns or not to criminal justice system following treatment. The signs and indicators seem to be quite positive, and criminal justice clients who do experience rehabilitation have better potential for remaining out of the system after treatment.
