Criminal justice client rehabs are available being a significantly better option than prison time or significant fines for many who have already been convicted of any type of alcohol or drug related crime. For instance, someone who has been in prison for driving while impaired of alcohol or drugs may qualify to receive rehab services for their problem as an alternative to serving time in prison. 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 opportunity select a criminal justice client rehab as an alternative to other sentencing, and it is well-advised they reap the benefits of it when it is an alternative. The theory behind criminal justice client rehabs is it is way 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 approach 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 who take part in treatment have a better potential for remaining out of the judicial system following treatment.
