Criminal justice client rehabs can be considered like a significantly better option than incarceration or heavy fines for many who have been convicted of any type of alcohol or drug related crime. For instance, somebody who has been in prison for driving while impaired of alcohol or drugs may qualify to obtain rehab services for his or her problem rather than serving time in jail. The judge may even order that the individual receive rehab, either alone or in addition to other sentencing. First-time offenders in particular tend to be given the ability to go with a criminal justice client rehab as an alternative to other sentencing, and it is well-advised they make the most of it if it is a choice. The idea 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 carried out 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 treatment. The signs and indicators seem quite positive, and criminal justice clients who experience treatment have better probability of remaining out of the system after rehabilitation.
