Criminal justice client rehabs are available being a significantly better option than time in jail or significant fines for those who have already been convicted of any type of alcohol or drug related crime. By way of example, a person who has been in prison for driving under the influence of drugs or alcohol may qualify to get rehab services for problem as an alternative to serving time in prison. The judge could even order that the individual receive treatment, either alone or together with other consequences. Very first time offenders in particular are often given the chance to go with a criminal justice client rehab as opposed to other sentencing, and it is well-advised they take advantage of it when it is an alternative. The concept behind criminal justice client rehabs is that it is way more effective and efficient to invest time and energy into rehabilitation than enforcement of other consequences. Much research has been done to find out how effective this strategy 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 that take part in rehabilitation have a better chance of remaining out of the judicial system after rehabilitation.
