Criminal justice client rehabs can be considered like a far better option than incarceration or significant fines for individuals who have already been convicted of any kind of alcohol or drug related crime. By way of example, anyone who has been found guilty of driving under the influence of drugs or alcohol may qualify for rehabilitation services for problem rather than serving time in prison. The judge could even order the individual receive rehab, either alone or in addition to other sentencing. First time offenders specifically in many cases are given the opportunity to select a criminal justice client rehab as an alternative to other sentencing, and it is well-advised that they reap the benefits of it when it is a choice. The theory behind criminal justice client rehabs is that it is much more effective and efficient to invest time and effort into rehab than punishment. Much research has been done to discover 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 seem quite positive, and criminal justice clients that experience rehab have a much better probability of remaining out of the system following rehab.
