Criminal justice client rehabs are available as being a significantly better option than jail time or heavy fines for individuals who have already been convicted of any kind of alcohol or drug related crime. For example, a person who has been in prison for driving drunk of alcohol or drugs may qualify to get treatment services for their problem instead of serving time in prison. The judge could even order the individual receive treatment, either alone or along with other consequences. First time offenders specifically will often be given the chance to choose a criminal justice client rehab rather than other sentencing, and it is well-advised that they reap the benefits of it if it is a possibility. The concept behind criminal justice client rehabs is it is much more efficient and effective to invest time and energy 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 do take part in rehab have a much better chance of remaining out of the system after rehabilitation.
