Criminal justice client rehabs are available as a considerably better option than prison time or significant fines for those who have been convicted of any kind of alcohol or drug related crime. As an example, anyone who has been in prison for driving while impaired of alcohol or drugs may qualify for rehab services for his or her problem rather than serving time in prison. The judge may even order the individual receive rehab, either alone or along with other consequences. First-time offenders specifically will often be given the chance 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's an option. The concept behind criminal justice client rehabs is that it is far more efficient and effective to invest commitment into rehabilitation than enforcement of other consequences. Much research has been done to observe how effective this process is on recidivism rates, i.e. if the criminal justice client returns or not to criminal justice system following rehab. The signs and indicators seem to be quite positive, and criminal justice clients that do take part in rehabilitation have a much better chance of remaining out of the system after rehab.
