Criminal justice client rehabs are available as a far better option than jail 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 to receive rehab services for their problem as an alternative to serving time in jail. The judge may even order that the individual receive rehab, either alone or along with other sentencing. First time offenders specifically tend to be given the ability to select a criminal justice client rehab as an alternative to other sentencing, and it is highly recommended that they take advantage of it if it's a choice. The theory behind criminal justice client rehabs is it is way more effective and efficient to invest commitment into rehabilitation than enforcement of other consequences. Much research has been carried out to find out how effective this process is on recidivism rates, i.e. if the criminal justice client returns or not to criminal justice system following treatment. The signs and indicators appear to be quite positive, and criminal justice clients who experience rehabilitation have better potential for remaining out of the system following rehabilitation.
