Criminal justice client rehabs are available like a significantly better option than time in jail or heavy fines for those who have already been convicted of any type of alcohol or drug related crime. As an example, somebody who has been found guilty of driving while impaired of alcohol or drugs may be eligible to obtain rehabilitation services for his or her problem as an alternative to serving time in jail. The judge could even order the individual receive treatment, either alone or as well as other consequences. First-time offenders specifically tend to be given the ability to select a criminal justice client rehab as an alternative to other sentencing, and it is highly recommended that they benefit from it if it is an option. The theory behind criminal justice client rehabs is that it is way more effective and efficient to invest time and effort into rehabilitation than punishment. Much research has been done to find out how effective this method is on recidivism rates, i.e. if the criminal justice client returns or not to criminal justice system following treatment. The signs and indicators seem to be quite positive, and criminal justice clients who take part in rehabilitation have better probability of remaining out of the judicial system after rehabilitation.
