Criminal justice client rehabs are available as being a significantly better option than jail time or significant fines for individuals who have been convicted of any type of drug or alcohol related crime. For example, anyone who has been in prison for driving under the influence of drugs or alcohol may qualify to obtain rehab services for their problem as opposed to serving time in prison. The judge might order the individual receive rehab, either alone or along with other consequences. First-time offenders in particular are often given the chance to go with a criminal justice client rehab as opposed to other sentencing, and it is highly recommended they benefit from it when it is an option. The theory behind criminal justice client rehabs is that it is much more efficient and effective to invest effort and time into treatment than enforcement of other consequences. Much research has been done to see how effective this approach is on recidivism rates, i.e. if the individual returns or not to criminal justice system following rehab. All indicators seem quite positive, and criminal justice clients that take part in treatment have better possibility of remaining out of the judicial system after treatment.
