Criminal justice client rehabs are available being a significantly better option than prison time or significant fines for individuals who have been convicted of any sort of alcohol or drug related crime. For instance, a person who has been in prison for dui of alcohol or drugs may qualify for rehab services for their problem rather than serving time in jail. The judge could even order that the individual receive rehabilitation, either alone or in addition to other sentencing. First time offenders in particular tend to be given the ability to choose a criminal justice client rehab as an alternative to other sentencing, and it is highly recommended they make the most of it when it is a choice. The theory behind criminal justice client rehabs is that it is way more effective and efficient to invest effort and time into rehab than enforcement of other consequences. Much research has been done to see 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 that do experience rehab have better potential for remaining out of the judicial system after treatment.
