Criminal justice client rehabs are available as being a far better option than time in jail or significant fines for those who have been convicted of any sort of alcohol or drug related crime. As an example, a person who has been found guilty of driving while impaired of alcohol or drugs may be eligible for treatment services for his or her problem rather than serving time in jail. The judge could even order that the individual receive treatment, either alone or together with other sentencing. First time offenders in particular are often given the opportunity to select a criminal justice client rehab instead of other sentencing, and it is highly recommended they take advantage of it when it is a possibility. The idea behind criminal justice client rehabs is that it is way more effective and efficient to invest time and energy into treatment than enforcement of other consequences. Much research has been done to find out how effective this approach is on recidivism rates, i.e. if the criminal justice client returns or not to criminal justice system following rehab. All indicators seem quite positive, and criminal justice clients that do take part in rehab have a much better probability of remaining out of the system following rehabilitation.
