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 drug or alcohol related crime. By way of example, a person who has been found guilty of driving drunk of alcohol or drugs may be eligible to get treatment services for their problem as an alternative to serving time in prison. The judge might even order that the individual receive treatment, either alone or together with other sentencing. First time offenders specifically are often given the opportunity select a criminal justice client rehab as opposed to other sentencing, and it is highly recommended that they take advantage of it when it is a choice. The theory behind criminal justice client rehabs is it is far more effective and efficient to invest effort and time into rehab than enforcement of other consequences. Much research has been completed to see how effective this method is on recidivism rates, i.e. if the individual returns or not to criminal justice system following treatment. All indicators seem to be quite positive, and criminal justice clients who do take part in treatment have a better chance of remaining out of the system following rehabilitation.
