Criminal justice client rehabs can be considered like a far better option than incarceration or significant fines for those who have already been convicted of any kind of alcohol or drug related crime. As an example, anyone who has been in prison for dui of alcohol or drugs may be eligible to get treatment services for their problem as an alternative to serving time in jail. The judge might order the individual receive rehabilitation, either alone or together with other sentencing. First time offenders specifically in many cases are given the ability to choose a criminal justice client rehab as opposed to other sentencing, and it is highly recommended they benefit from it if it's an option. The theory behind criminal justice client rehabs is that it is much more effective and efficient to invest time and energy into treatment 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. The signs and indicators appear to be quite positive, and criminal justice clients that do experience rehab have a better potential for remaining out of the judicial system following treatment.
