Criminal justice client rehabs are available as being a considerably better option than incarceration or heavy fines for many who have already been convicted of any sort of drug or alcohol related crime. By way of example, someone who has been in prison for driving while impaired of drugs or alcohol may be eligible to receive rehabilitation services for problem instead of serving time in prison. The judge might order that the individual receive rehab, either alone or together with other sentencing. First-time offenders in particular tend to be given the ability to go with a criminal justice client rehab rather than other sentencing, and it is highly recommended they make the most of it if it is a possibility. The idea behind criminal justice client rehabs is it is way more effective and efficient to invest effort and time into rehabilitation than punishment. Much research has been carried out to discover how effective this method is on recidivism rates, i.e. if the individual returns or not to criminal justice system following treatment. The signs and indicators appear to be quite positive, and criminal justice clients that experience rehabilitation have better probability of remaining out of the system after rehabilitation.
