Criminal justice client rehabs are available as a considerably better option than jail time or significant fines for those who have been convicted of any kind of alcohol or drug related crime. By way of example, anyone who has been in prison for driving drunk of drugs or alcohol may be eligible to obtain treatment services because of their 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 sentencing. First time offenders in particular tend to be given the opportunity to choose a criminal justice client rehab as an alternative to other sentencing, and it is well-advised that they benefit from it when it is an option. The theory behind criminal justice client rehabs is that it is far more effective and efficient to invest commitment into treatment than punishment. Much research has been carried out to see how effective this process is on recidivism rates, i.e. if the individual returns or not to criminal justice system following rehab. The signs and indicators seem to be quite positive, and criminal justice clients who do take part in rehabilitation have better probability of remaining out of the system following rehabilitation.
