Criminal justice client rehabs are available like a significantly better option than time in jail or significant fines for individuals who have already been convicted of any type of alcohol or drug related crime. As an example, a person who has been found guilty of driving drunk of alcohol or drugs may be eligible for treatment services because of their problem instead of serving time in prison. The judge might even order the individual receive rehabilitation, either alone or along with other consequences. Very first time offenders specifically tend to be given the ability to go with a criminal justice client rehab instead of other sentencing, and it is highly recommended that they make the most of it if it is a possibility. The theory behind criminal justice client rehabs is it is far more effective and efficient to invest time and energy into rehab than enforcement of other consequences. Much research has been done to see how effective this approach is on recidivism rates, i.e. if the individual returns or not to criminal justice system following rehab. The signs and indicators appear to be quite positive, and criminal justice clients who experience rehabilitation have a much better potential for remaining out of the system after rehabilitation.
