Criminal justice client rehabs can be considered being a considerably better option than prison time or significant fines for those who have already been convicted of any sort of alcohol or drug related crime. For instance, anyone who has been found guilty of driving while impaired of drugs or alcohol may qualify to get rehab services for his or her problem rather than serving time in prison. The judge could even order the individual receive treatment, either alone or in addition to other consequences. First time offenders specifically will often be given the opportunity go with a criminal justice client rehab instead of other sentencing, and it is highly recommended they benefit from it if it is an option. The theory behind criminal justice client rehabs is it is much more efficient and effective to invest effort and time into treatment than enforcement of other consequences. Much research has been carried out to discover how effective this method is on recidivism rates, i.e. if the individual returns or not to criminal justice system following rehabilitation. All indicators appear to be quite positive, and criminal justice clients who experience rehab have a better probability of remaining out of the system following rehabilitation.
