Criminal justice client rehabs are available being a considerably better option than time in jail or significant fines for those who have been convicted of any kind of alcohol or drug related crime. As an example, a person who has been found guilty of driving drunk of alcohol or drugs may qualify to get rehabilitation services for his or her problem instead of serving time in jail. The judge may even order the individual receive rehab, either alone or in addition to other consequences. Very first time offenders specifically will often be given the opportunity to choose a criminal justice client rehab rather than other sentencing, and it is well-advised they benefit from it when it is an option. The theory behind criminal justice client rehabs is that it is much more effective and efficient to invest effort and time into rehab than punishment. Much research has been completed to see how effective this method is on recidivism rates, i.e. if the criminal justice client returns or not to criminal justice system following rehab. The signs and indicators seem to be quite positive, and criminal justice clients who take part in treatment have better chance of remaining out of the judicial system after treatment.
