Criminal justice client rehabs can be considered like a far better option than prison time or heavy fines for those who have been convicted of any sort of drug or alcohol related crime. For example, a person who has been in prison for driving under the influence of drugs or alcohol may be eligible to obtain rehabilitation 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 along with other sentencing. Very first time offenders in particular will often be given the ability to choose a criminal justice client rehab as an alternative to other sentencing, and it is highly recommended that they make the most of it if it is a choice. The theory behind criminal justice client rehabs is it is way more effective and efficient to invest time and energy into rehab than enforcement of other consequences. Much research has been carried out to see how effective this approach 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 take part in treatment have a better probability of remaining out of the judicial system following treatment.
