Criminal justice client rehabs are available as a far better option than time in jail or significant fines for individuals who have already been convicted of any kind of alcohol or drug related crime. By way of example, someone who has been found guilty of driving drunk of alcohol or drugs may qualify to receive rehab services for their problem rather than serving time in prison. The judge might order that the individual receive rehabilitation, either alone or as well as other sentencing. First time offenders in particular in many cases are given the ability to choose a criminal justice client rehab as an alternative to other sentencing, and it is well-advised that they make the most of it when it is a possibility. The concept behind criminal justice client rehabs is it is way more efficient and effective to invest time and effort into treatment than enforcement of other consequences. Much research has been done to find out how effective this approach is on recidivism rates, i.e. if the individual returns or not to criminal justice system following rehab. All indicators appear to be quite positive, and criminal justice clients that do take part in treatment have a better probability of remaining out of the judicial system following rehabilitation.
