Criminal justice client rehabs can be considered as a significantly better option than prison time or significant fines for those who have been convicted of any type of alcohol or drug related crime. As an example, a person who has been found guilty of driving while impaired of drugs or alcohol may qualify to obtain treatment services because of their problem rather than serving time in jail. The judge may even order the individual receive treatment, either alone or in addition to other consequences. First time offenders in particular will often be given the chance to pick a criminal justice client rehab rather than other sentencing, and it is well-advised that they reap the benefits of it if it is a choice. The theory behind criminal justice client rehabs is it is far more efficient and effective to invest time and effort into rehabilitation than enforcement of other consequences. Much research has been done to observe how effective this method is on recidivism rates, i.e. if the individual returns or not to criminal justice system following rehabilitation. The signs and indicators appear to be quite positive, and criminal justice clients that take part in rehab have a better potential for remaining out of the system after rehab.
