Criminal justice client rehabs can be considered being a considerably better option than jail time or significant fines for those who have already been convicted of any type of drug or alcohol related crime. By way of example, somebody who has been found guilty of driving under the influence of drugs or alcohol may qualify to get treatment services for their problem as opposed to serving time in prison. The judge could even order the individual receive treatment, either alone or along with other sentencing. New offenders in particular in many cases are given the chance to select a criminal justice client rehab as an alternative to other sentencing, and it is highly recommended that they reap the benefits of it if it is an option. The theory behind criminal justice client rehabs is it is way more efficient and effective to invest time and effort into rehab than enforcement of other consequences. Much research has been done to observe how effective this approach is on recidivism rates, i.e. if the criminal justice client returns or not to criminal justice system following treatment. The signs and indicators appear to be quite positive, and criminal justice clients who do take part in rehab have a better possibility of remaining out of the system following treatment.
