Criminal justice client rehabs can be considered as a significantly better option than incarceration or significant fines for those who have already been convicted of any type of drug or alcohol related crime. For instance, someone who has been found guilty of driving while impaired of alcohol or drugs may be eligible to get treatment services for his or her problem rather than serving time in prison. The judge may even order the individual receive treatment, either alone or in addition to other sentencing. First-time offenders specifically are often given the chance to choose a criminal justice client rehab instead of other sentencing, and it is highly recommended they make the most of it when it is a possibility. The theory behind criminal justice client rehabs is that it is much more effective and efficient to invest effort and time into treatment than punishment. Much research has been done to find out how effective this process is on recidivism rates, i.e. if the individual returns or not to criminal justice system following rehabilitation. The signs and indicators appear to be quite positive, and criminal justice clients that experience treatment have better chance of remaining out of the judicial system after rehabilitation.
