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 drug or alcohol related crime. By way of example, a person who has been in prison for driving under the influence of drugs or alcohol may be eligible to receive rehab services for their problem as opposed to serving time in prison. The judge might order the individual receive rehab, either alone or in addition to other sentencing. First time offenders specifically are often given the opportunity to go with a criminal justice client rehab rather than other sentencing, and it is well-advised they take advantage of it if it's a possibility. The idea behind criminal justice client rehabs is it is much more efficient and effective to invest commitment into treatment than enforcement of other consequences. Much research has been carried out to see how effective this method is on recidivism rates, i.e. if the individual returns or not to criminal justice system following rehabilitation. All indicators seem to be quite positive, and criminal justice clients that do take part in treatment have better probability of remaining out of the system following rehab.
