Criminal justice client rehabs are available as being a significantly better option than time in jail or heavy fines for individuals who have already been convicted of any kind of drug or alcohol related crime. As an example, someone who has been in prison for driving drunk of alcohol or drugs may qualify to obtain rehab services because of their problem rather than serving time in jail. The judge may even order the individual receive treatment, either alone or along with other consequences. First time offenders specifically tend to be given the ability to select a criminal justice client rehab rather than other sentencing, and it is highly recommended they benefit from it when it is a choice. The concept behind criminal justice client rehabs is it is way more effective and efficient to invest time and effort into treatment than punishment. Much research has been done to find out how effective this method is on recidivism rates, i.e. if the individual returns or not to criminal justice system following treatment. All indicators appear to be quite positive, and criminal justice clients who do take part in rehabilitation have better probability of remaining out of the judicial system after rehabilitation.
