Criminal justice client rehabs are available as a significantly better option than time in jail or significant fines for individuals who have already been convicted of any sort of alcohol or drug related crime. For instance, anyone who has been in prison for driving under the influence of alcohol or drugs may qualify to receive rehab services for their problem instead of serving time in jail. The judge could even order that the individual receive treatment, either alone or in addition to other consequences. First-time offenders in particular are often given the ability to pick a criminal justice client rehab as an alternative to other sentencing, and it is well-advised that they reap the benefits of it if it is a possibility. The idea behind criminal justice client rehabs is it is much more efficient and effective to invest time and effort into treatment than enforcement of other consequences. Much research has been completed to see how effective this approach is on recidivism rates, i.e. if the criminal justice client returns or not to criminal justice system following rehabilitation. All indicators seem to be quite positive, and criminal justice clients who do take part in treatment have a better chance of remaining out of the system after rehabilitation.
