Criminal justice client rehabs are available like a significantly better option than incarceration or heavy fines for those who have already been convicted of any sort of drug or alcohol related crime. By way of example, someone who has been found guilty of driving while impaired of drugs or alcohol may qualify to get rehab services for problem rather than serving time in prison. The judge could even order that the individual receive rehabilitation, either alone or together with other sentencing. First-time offenders in particular are often given the chance to select a criminal justice client rehab as opposed to other sentencing, and it is highly recommended they reap the benefits of it when it is an option. The idea behind criminal justice client rehabs is that it is way more effective and efficient to invest effort and time into rehab than enforcement of other consequences. Much research has been done to see how effective this process is on recidivism rates, i.e. if the criminal justice client returns or not to criminal justice system following rehab. All indicators seem to be quite positive, and criminal justice clients that do take part in rehab have a much better possibility of remaining out of the system following rehabilitation.
