Criminal justice client rehabs are available as being a considerably better option than time in jail or heavy fines for individuals who have already been convicted of any sort of alcohol or drug related crime. For instance, a person who has been in prison for driving while impaired of drugs or alcohol may qualify to receive rehab services for his or her problem rather than serving time in prison. The judge might even order the individual receive rehab, either alone or in addition to other sentencing. First time offenders in particular tend to be given the opportunity to go with a criminal justice client rehab as opposed to other sentencing, and it is highly recommended they take advantage of it if it's an option. The idea behind criminal justice client rehabs is that it is much more effective and efficient to invest time and energy into rehab than enforcement of other consequences. Much research has been done to discover how effective this approach is on recidivism rates, i.e. if the criminal justice client returns or not to criminal justice system following rehabilitation. All indicators appear to be quite positive, and criminal justice clients who take part in rehab have a better probability of remaining out of the judicial system following rehabilitation.
