Criminal justice client rehabs are available as a considerably better option than incarceration or heavy fines for many who have already been convicted of any sort of drug or alcohol related crime. For example, someone who has been found guilty of driving while impaired of drugs or alcohol may qualify for rehabilitation services for his or her problem rather than serving time in prison. The judge could even order the individual receive treatment, either alone or along with other consequences. Very first time offenders specifically in many cases are given the ability to pick a criminal justice client rehab rather than other sentencing, and it is well-advised they benefit from it if it is an alternative. The theory behind criminal justice client rehabs is it is far more efficient and effective to invest effort and time into rehabilitation 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 individual returns or not to criminal justice system following rehab. The signs and indicators seem to be quite positive, and criminal justice clients who experience treatment have better probability of remaining out of the system after rehabilitation.
