Criminal justice client rehabs are available like a far better option than jail time or significant 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 obtain rehabilitation services for their problem as opposed to serving time in jail. The judge may even order the individual receive treatment, either alone or along with other sentencing. Very 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 take advantage of it if it is a choice. The concept behind criminal justice client rehabs is that it is far more efficient and effective to invest time and energy into treatment than enforcement of other consequences. Much research has been carried out to find out how effective this approach is on recidivism rates, i.e. if the individual returns or not to criminal justice system following rehabilitation. The signs and indicators seem to be quite positive, and criminal justice clients who do take part in rehab have a much better chance of remaining out of the judicial system following treatment.
