Criminal justice client rehabs are available being a far better option than time in jail or heavy fines for individuals who have already been convicted of any kind of drug or alcohol related crime. For example, a person who has been in prison for driving drunk of alcohol or drugs may qualify to obtain treatment services for his or her problem as opposed to serving time in prison. The judge might order the individual receive treatment, either alone or together with other sentencing. New 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 reap the benefits of it if it's an alternative. The concept behind criminal justice client rehabs is that it is far more efficient and effective to invest time and effort into rehab than enforcement of other consequences. Much research has been done to find out how effective this approach is on recidivism rates, i.e. if the individual returns or not to criminal justice system following treatment. The signs and indicators appear to be quite positive, and criminal justice clients that do take part in treatment have a better chance of remaining out of the judicial system following rehabilitation.
