Criminal justice client rehabs are available like a far 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, a person who has been found guilty of driving while impaired of alcohol or drugs may qualify to receive rehab services for his or her problem instead of serving time in prison. The judge could even order that the individual receive rehab, either alone or together with other consequences. Very first time offenders specifically are often given the opportunity to pick a criminal justice client rehab as opposed to other sentencing, and it is well-advised that they reap the benefits of it if it is an option. The theory behind criminal justice client rehabs is that it is far more effective and efficient to invest effort and time into treatment than punishment. Much research has been carried out to observe how effective this method is on recidivism rates, i.e. if the individual returns or not to criminal justice system following treatment. All indicators appear to be quite positive, and criminal justice clients that do experience rehab have a much better possibility of remaining out of the system following treatment.
