Criminal justice client rehabs are available as a far better option than incarceration or heavy fines for those who have already been convicted of any type of alcohol or drug related crime. As an example, somebody who has been in prison for dui of alcohol or drugs may be eligible to receive treatment services because of their problem as opposed to serving time in prison. The judge could even order that the individual receive treatment, either alone or in addition to other sentencing. Very first time offenders in particular tend to be given the chance to choose a criminal justice client rehab as an alternative to other sentencing, and it is highly recommended that they reap the benefits of it when it is an option. The theory behind criminal justice client rehabs is that it is far more effective and efficient to invest time and energy into treatment than enforcement of other consequences. Much research has been done to discover how effective this process is on recidivism rates, i.e. if the criminal justice client returns or not to criminal justice system following treatment. All indicators appear to be quite positive, and criminal justice clients who do take part in rehabilitation have better possibility of remaining out of the system following rehabilitation.
