Criminal justice client rehabs are available as being a considerably better option than prison time or heavy fines for individuals who have been convicted of any type of drug or alcohol related crime. As an example, somebody who has been found guilty of dui of alcohol or drugs may be eligible for treatment services because of their problem as opposed to serving time in jail. The judge could even order that the individual receive treatment, either alone or in addition to other sentencing. First time offenders in particular are often given the opportunity to choose a criminal justice client rehab rather than 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 effective and efficient to invest time and effort 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 criminal justice client returns or not to criminal justice system following rehab. The signs and indicators seem quite positive, and criminal justice clients who take part in rehab have a much better chance of remaining out of the judicial system following rehabilitation.
