Criminal justice client rehabs are available being a far better option than time in jail or heavy fines for those who have already been convicted of any kind of alcohol or drug related crime. For instance, somebody who has been in prison for driving while impaired of drugs or alcohol may qualify to get treatment services for problem as an alternative to serving time in jail. The judge might order the individual receive rehab, either alone or along with other sentencing. First time offenders in particular will often be given the ability to choose a criminal justice client rehab as opposed to other sentencing, and it is highly recommended that they reap the benefits of it when it is an alternative. The theory behind criminal justice client rehabs is it is much more effective and efficient to invest effort and time into treatment than enforcement of other consequences. Much research has been carried out to see how effective this method is on recidivism rates, i.e. if the individual returns or not to criminal justice system following treatment. The signs and indicators appear to be quite positive, and criminal justice clients that do take part in treatment have a much better chance of remaining out of the judicial system following rehabilitation.
