Criminal justice client rehabs are available as being a considerably better option than incarceration or significant fines for many who have already been convicted of any sort of alcohol or drug related crime. For instance, someone who has been in prison for driving drunk of alcohol or drugs may qualify for rehab services for their problem instead of serving time in jail. The judge might order that the individual receive rehab, either alone or along with other consequences. New offenders specifically will often be given the opportunity to pick a criminal justice client rehab instead of other sentencing, and it is well-advised they benefit from it if it is a possibility. The theory behind criminal justice client rehabs is that it is much more effective and efficient to invest time and energy into rehab than punishment. Much research has been done to find out how effective this process 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 who do take part in rehab have a better probability of remaining out of the system following rehab.
