Criminal justice client rehabs can be considered as being a significantly better option than time in jail or significant fines for many who have already been convicted of any kind of alcohol or drug related crime. For instance, anyone who has been in prison for driving while impaired of alcohol or drugs may qualify to obtain rehab services for his or her problem instead of serving time in prison. The judge may even order that the individual receive rehabilitation, either alone or in addition to other consequences. First time offenders in particular will often be given the opportunity to choose a criminal justice client rehab instead of other sentencing, and it is well-advised they reap the benefits of it if it's a possibility. The concept behind criminal justice client rehabs is that it is much more effective and efficient to invest time and effort into treatment than enforcement of other consequences. Much research has been done to observe how effective this approach is on recidivism rates, i.e. if the criminal justice client returns or not to criminal justice system following rehab. All indicators appear to be quite positive, and criminal justice clients who experience treatment have a much better chance of remaining out of the system after rehabilitation.
