Criminal justice client rehabs can be considered as being a significantly better option than prison time or significant fines for individuals who have already been convicted of any kind of drug or alcohol related crime. As an example, someone who has been found guilty of driving drunk of alcohol or drugs may qualify to obtain treatment services for their problem instead of serving time in prison. The judge may even order that the individual receive rehab, either alone or as well as other consequences. First-time offenders in particular will often be given the chance to choose a criminal justice client rehab as an alternative to other sentencing, and it is highly recommended that they make the most of it when it is a possibility. The idea behind criminal justice client rehabs is that it is far more efficient and effective to invest time and effort into treatment than enforcement of other consequences. Much research has been done to observe how effective this method is on recidivism rates, i.e. if the criminal justice client returns or not to criminal justice system following rehabilitation. The signs and indicators seem to be quite positive, and criminal justice clients that take part in rehabilitation have a better potential for remaining out of the system after treatment.
