Criminal justice client rehabs can be considered like a far better option than time in jail or heavy fines for individuals who have already been convicted of any kind of alcohol or drug related crime. As an example, someone who has been found guilty of driving drunk of drugs or alcohol may qualify for treatment services for problem rather than serving time in prison. The judge might even order the individual receive rehab, either alone or in addition to other consequences. First time offenders in particular tend to be given the chance to go with a criminal justice client rehab as opposed to other sentencing, and it is highly recommended that they take advantage of it if it is an alternative. The theory behind criminal justice client rehabs is that it is way more efficient and effective to invest commitment into rehab than enforcement of other consequences. 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 rehab. All indicators appear to be quite positive, and criminal justice clients that do take part in rehab have a better probability of remaining out of the system after rehab.
