Criminal justice client rehabs are available as a far better option than prison time or heavy fines for individuals who have already been convicted of any kind of alcohol or drug related crime. For instance, somebody who has been found guilty of dui of alcohol or drugs may be eligible to receive rehab services because of their problem instead of serving time in jail. The judge might even order the individual receive rehabilitation, either alone or together with other consequences. First time offenders specifically will often be given the ability to pick a criminal justice client rehab as opposed to other sentencing, and it is highly recommended that they make the most of it when it is a possibility. The theory behind criminal justice client rehabs is that it is way more efficient and effective to invest time and effort into rehabilitation than punishment. Much research has been carried out 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 seem to be quite positive, and criminal justice clients who do take part in rehab have a better chance of remaining out of the judicial system after rehabilitation.
