Criminal justice client rehabs can be considered being a significantly better option than jail time or significant fines for individuals who have already been convicted of any sort of drug or alcohol related crime. As an example, anyone who has been in prison for driving under the influence of alcohol or drugs may be eligible to obtain rehabilitation services for his or her problem as an alternative to serving time in prison. The judge might even order the individual receive treatment, either alone or as well as other consequences. First-time offenders specifically are often given the chance to go with a criminal justice client rehab instead of other sentencing, and it is well-advised that they reap the benefits of it if it is an alternative. The theory behind criminal justice client rehabs is it is way more effective and efficient to invest time and effort into rehabilitation than enforcement of other consequences. Much research has been done to see how effective this approach is on recidivism rates, i.e. if the criminal justice client returns or not to criminal justice system following rehabilitation. All indicators appear to be quite positive, and criminal justice clients who do take part in rehab have a much better probability of remaining out of the system following rehabilitation.
