Criminal justice client rehabs can be considered like a considerably better option than prison time or heavy fines for those who have already been convicted of any type of alcohol or drug related crime. For example, somebody who has been in prison for driving while impaired of drugs or alcohol may be eligible to obtain rehab services for their problem as an alternative to serving time in jail. The judge could even order that the individual receive rehab, either alone or along with other sentencing. New offenders specifically tend to be given the opportunity to pick a criminal justice client rehab as an alternative to other sentencing, and it is well-advised they make the most of it if it is a choice. The theory behind criminal justice client rehabs is that it is way more effective and efficient to invest commitment into rehab than enforcement of other consequences. Much research has been done to discover how effective this process is on recidivism rates, i.e. if the individual returns or not to criminal justice system following rehab. All indicators seem to be quite positive, and criminal justice clients who do take part in rehabilitation have better possibility of remaining out of the system following rehabilitation.
