Criminal justice client rehabs are available as being a far better option than prison time or significant fines for many who have already been convicted of any sort of drug or alcohol related crime. For example, anyone who has been found guilty of driving under the influence of drugs or alcohol may qualify for rehab services because of their problem instead of serving time in prison. The judge might even order the individual receive rehabilitation, either alone or along with other consequences. New offenders in particular are often given the chance to pick a criminal justice client rehab as an alternative to other sentencing, and it is highly recommended they take advantage of it if it is a choice. The theory behind criminal justice client rehabs is that it is way more effective and efficient to invest effort and time into rehabilitation than enforcement of other consequences. Much research has been carried out 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 seem to be quite positive, and criminal justice clients that do experience rehab have a much better probability of remaining out of the system after treatment.
