Criminal justice client rehabs are available as being a far better option than prison time or significant fines for those who have already been convicted of any sort of alcohol or drug related crime. For instance, a person who has been in prison for driving drunk of drugs or alcohol may qualify to receive rehabilitation services for his or her problem rather than serving time in prison. The judge might even order that the individual receive rehabilitation, either alone or along with other consequences. First-time offenders specifically tend to be given the opportunity select a criminal justice client rehab as opposed to other sentencing, and it is well-advised they take advantage of it if it is an option. The idea behind criminal justice client rehabs is it is far more effective and efficient to invest effort and time into treatment than punishment. Much research has been carried out to see how effective this approach is on recidivism rates, i.e. if the individual returns or not to criminal justice system following treatment. All indicators appear to be quite positive, and criminal justice clients who do experience rehabilitation have a better probability of remaining out of the system after rehabilitation.
