Criminal justice client rehabs are available as being a considerably better option than time in jail or significant fines for those who have already been convicted of any sort of drug or alcohol related crime. By way of example, someone who has been found guilty of driving drunk of alcohol or drugs may be eligible to obtain rehabilitation services for his or her problem instead of serving time in prison. The judge might even order the individual receive rehab, either alone or along with other sentencing. New offenders in particular in many cases are given the chance to choose a criminal justice client rehab as an alternative to other sentencing, and it is highly recommended they benefit from it when it is an alternative. The idea behind criminal justice client rehabs is it is way more effective and efficient to invest effort and time into treatment than punishment. Much research has been done to find out how effective this method is on recidivism rates, i.e. if the individual returns or not to criminal justice system following rehabilitation. The signs and indicators appear to be quite positive, and criminal justice clients who experience treatment have a much better possibility of remaining out of the judicial system following treatment.
