Criminal justice client rehabs are available being a far better option than incarceration or heavy fines for individuals who have already been convicted of any sort of alcohol or drug related crime. For example, someone who has been in prison for driving under the influence of alcohol or drugs may qualify to obtain rehab services for problem as an alternative to serving time in prison. The judge might even order the individual receive treatment, either alone or in addition to other sentencing. New offenders specifically will often be given the ability to go with a criminal justice client rehab as an alternative to other sentencing, and it is well-advised that they make the most of it if it is an alternative. The idea behind criminal justice client rehabs is that it is much more efficient and effective to invest effort and time into rehabilitation than enforcement of other consequences. Much research has been done to see how effective this strategy is on recidivism rates, i.e. if the individual returns or not to criminal justice system following treatment. The signs and indicators seem to be quite positive, and criminal justice clients who experience rehab have better probability of remaining out of the system after rehab.
