Criminal justice client rehabs can be considered like a significantly better option than prison time or significant fines for those who have already been convicted of any kind of drug or alcohol related crime. For instance, a person who has been found guilty of driving under the influence of drugs or alcohol may be eligible to receive treatment services for problem rather than serving time in prison. The judge might even order the individual receive rehabilitation, either alone or as well as other consequences. New offenders specifically are often given the opportunity to go with a criminal justice client rehab as opposed to other sentencing, and it is well-advised they take advantage of it if it is an option. The theory behind criminal justice client rehabs is that it is much more effective and efficient to invest commitment into treatment than punishment. Much research has been carried out 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. The signs and indicators seem quite positive, and criminal justice clients who take part in treatment have better probability of remaining out of the system after rehab.
