Criminal justice client rehabs are available being a significantly better option than time in jail or heavy fines for many who have been convicted of any type of drug or alcohol related crime. For example, somebody who has been in prison for dui of drugs or alcohol may be eligible to obtain treatment services because of their problem rather than 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 in particular are often given the chance to pick a criminal justice client rehab as opposed to other sentencing, and it is highly recommended that they make the most of it if it is an option. The theory behind criminal justice client rehabs is that it is far more effective and efficient to invest time and effort into rehab than punishment. Much research has been carried out to see how effective this method is on recidivism rates, i.e. if the individual returns or not to criminal justice system following rehabilitation. All indicators seem to be quite positive, and criminal justice clients who take part in treatment have better chance of remaining out of the judicial system following rehabilitation.
