Criminal justice client rehabs can be considered as being a significantly better option than prison time or significant fines for individuals who have been convicted of any kind of alcohol or drug related crime. As an example, a person who has been found guilty of driving under the influence of alcohol or drugs may qualify to receive treatment services because of their problem as opposed to serving time in jail. The judge may even order that the individual receive rehabilitation, either alone or as well as other sentencing. First-time offenders specifically will often be given the ability to pick a criminal justice client rehab instead of other sentencing, and it is highly recommended that they take advantage of it if it's a possibility. The theory behind criminal justice client rehabs is that it is far more effective and efficient to invest time and effort into rehabilitation than enforcement of other consequences. Much research has been carried out to see how effective this process is on recidivism rates, i.e. if the criminal justice client returns or not to criminal justice system following rehabilitation. The signs and indicators appear to be quite positive, and criminal justice clients that do take part in rehabilitation have better chance of remaining out of the system after rehabilitation.
