Criminal justice client rehabs are available as being a significantly better option than time in jail or heavy fines for individuals who have already been convicted of any sort of alcohol or drug related crime. For example, anyone who has been found guilty of driving while impaired of alcohol or drugs may qualify for rehab services for problem as an alternative to serving time in jail. The judge might order the individual receive rehab, either alone or in addition to other sentencing. New offenders specifically in many cases are given the opportunity go with a criminal justice client rehab rather than other sentencing, and it is well-advised that they make the most of it if it is an option. The theory behind criminal justice client rehabs is it is much more effective and efficient to invest time and energy 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 treatment. All indicators seem to be quite positive, and criminal justice clients who take part in rehabilitation have a better chance of remaining out of the system following rehabilitation.
