Criminal justice client rehabs can be considered as a far better option than jail time or heavy fines for those who have already been convicted of any type of alcohol or drug related crime. By way of example, anyone who has been in prison for driving drunk of drugs or alcohol may qualify to get rehab services because of their problem rather than serving time in jail. The judge may even order the individual receive rehab, either alone or together with other sentencing. First time offenders in particular tend to be given the ability to choose a criminal justice client rehab rather than other sentencing, and it is well-advised that they reap the benefits of it when it is an alternative. The theory behind criminal justice client rehabs is that it is far more effective and efficient to invest time and effort into treatment than enforcement of other consequences. Much research has been completed to discover how effective this strategy is on recidivism rates, i.e. if the criminal justice client returns or not to criminal justice system following rehab. The signs and indicators appear to be quite positive, and criminal justice clients that do take part in rehabilitation have a much better probability of remaining out of the judicial system after rehab.
