Criminal justice client rehabs are available as a considerably better option than incarceration or heavy fines for many who have already been convicted of any type of alcohol or drug related crime. For instance, someone who has been found guilty of driving while impaired of drugs or alcohol may qualify to receive rehab services because of their problem instead of serving time in prison. The judge may even order the individual receive rehabilitation, either alone or as well as other consequences. First-time offenders in particular in many cases are given the ability to select a criminal justice client rehab rather than other sentencing, and it is well-advised they make the most of it if it is an option. The idea behind criminal justice client rehabs is it is much more efficient and effective to invest effort and time into rehabilitation than enforcement of other consequences. Much research has been carried out to discover how effective this process is on recidivism rates, i.e. if the individual returns or not to criminal justice system following rehab. The signs and indicators appear to be quite positive, and criminal justice clients who do take part in rehabilitation have a better possibility of remaining out of the system following rehabilitation.
