Criminal justice client rehabs can be considered like a far better option than prison time or significant fines for individuals who have been convicted of any kind of drug or alcohol related crime. For instance, a person who has been in prison for driving while impaired of drugs or alcohol may qualify to receive rehabilitation services because of their problem instead of serving time in prison. The judge may even order that the individual receive rehabilitation, either alone or along with other sentencing. First time offenders specifically tend to be given the chance to choose a criminal justice client rehab as an alternative to other sentencing, and it is well-advised that they take advantage of it if it is an alternative. The theory behind criminal justice client rehabs is it is far more effective and efficient to invest time and energy into rehabilitation than enforcement of other consequences. Much research has been carried out to discover how effective this approach is on recidivism rates, i.e. if the individual returns or not to criminal justice system following rehab. The signs and indicators appear to be quite positive, and criminal justice clients that take part in rehabilitation have better possibility of remaining out of the judicial system following rehab.
