Criminal justice client rehabs are available like a considerably better option than prison time or heavy fines for those who have already been convicted of any type of alcohol or drug related crime. For instance, a person who has been found guilty of driving drunk of alcohol or drugs may qualify to obtain treatment services for his or her problem instead of serving time in prison. The judge might even order the individual receive rehabilitation, either alone or in addition to other consequences. Very first time offenders in particular are often given the opportunity to select a criminal justice client rehab as opposed to other sentencing, and it is well-advised that they take advantage of it if it is a choice. The concept behind criminal justice client rehabs is that it is much more efficient and effective to invest effort and time into treatment than enforcement of other consequences. Much research has been done to discover 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 appear to be quite positive, and criminal justice clients who take part in treatment have better chance of remaining out of the judicial system following treatment.
