Criminal justice client rehabs are available like a significantly better option than prison time or significant fines for many who have been convicted of any sort of alcohol or drug related crime. For example, somebody who has been in prison for driving under the influence of alcohol or drugs may be eligible to obtain rehab services for his or her problem as opposed to serving time in prison. The judge might order the individual receive rehab, either alone or as well as other consequences. New offenders in particular tend to be given the opportunity to choose a criminal justice client rehab rather than other sentencing, and it is highly recommended they reap the benefits 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 effort and time into rehab than enforcement of other consequences. Much research has been done to observe how effective this method 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 quite positive, and criminal justice clients who do take part in treatment have better chance of remaining out of the system after rehab.
