Criminal justice client rehabs are available like a far better option than incarceration or heavy fines for many who have been convicted of any sort of alcohol or drug related crime. As an example, somebody who has been found guilty of driving under the influence of alcohol or drugs may qualify for rehab services for his or her problem rather than serving time in jail. The judge may even order that the individual receive rehab, either alone or together with other sentencing. First-time offenders in particular in many cases are given the chance to choose a criminal justice client rehab rather than other sentencing, and it is highly recommended they take advantage of it if it is an alternative. The concept behind criminal justice client rehabs is that it is much more effective and efficient to invest time and effort into rehab than punishment. Much research has been carried out to find out how effective this approach is on recidivism rates, i.e. if the criminal justice client returns or not to criminal justice system following treatment. All indicators seem to be quite positive, and criminal justice clients who do experience rehab have a better chance of remaining out of the system after treatment.
