Criminal justice client rehabs are available as a considerably better option than incarceration or significant fines for many who have already been convicted of any kind of drug or alcohol related crime. For instance, a person who has been found guilty of driving while impaired of alcohol or drugs may be eligible to receive rehabilitation services because of their problem as an alternative to serving time in jail. The judge might even order that the individual receive rehab, either alone or together with other sentencing. Very first time offenders specifically are often given the opportunity go with a criminal justice client rehab instead of other sentencing, and it is well-advised they take advantage of it if it is a possibility. The idea behind criminal justice client rehabs is it is way more effective and efficient to invest time and effort into rehabilitation 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 rehab. The signs and indicators appear to be quite positive, and criminal justice clients that take part in rehabilitation have a better chance of remaining out of the system after rehabilitation.
