Criminal justice client rehabs are available as a far better option than prison time or significant fines for those who have already been convicted of any type of drug or alcohol related crime. As an example, a person who has been found guilty of driving while impaired of drugs or alcohol may qualify to obtain rehabilitation services for problem rather than serving time in prison. The judge could even order that the individual receive treatment, either alone or together with other consequences. First-time offenders specifically tend to be given the opportunity to select a criminal justice client rehab rather than other sentencing, and it is highly recommended they reap the benefits of it if it is a choice. The theory behind criminal justice client rehabs is it is far more efficient and effective to invest commitment into rehabilitation than punishment. Much research has been completed 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. The signs and indicators seem to be quite positive, and criminal justice clients who experience rehab have better potential for remaining out of the system following rehabilitation.
