Criminal justice client rehabs are available like a far better option than incarceration or heavy fines for those who have already been convicted of any kind of alcohol or drug related crime. For instance, a person who has been found guilty of driving while impaired of alcohol or drugs may qualify to receive rehab services for his or her problem as opposed to serving time in jail. The judge might order the individual receive rehabilitation, either alone or in addition to other sentencing. First-time offenders in particular in many cases are given the ability to 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 alternative. The concept behind criminal justice client rehabs is it is far more effective and efficient to invest time and effort into treatment than enforcement of other consequences. Much research has been carried out to discover how effective this method is on recidivism rates, i.e. if the individual returns or not to criminal justice system following rehab. All indicators appear to be quite positive, and criminal justice clients who take part in rehabilitation have better potential for remaining out of the judicial system after rehabilitation.
