Criminal justice client rehabs can be considered as being a significantly better option than prison time or heavy fines for individuals who have been convicted of any kind of alcohol or drug related crime. For example, anyone who has been found guilty of driving while impaired of alcohol or drugs may be eligible to obtain rehabilitation services for problem instead of serving time in jail. The judge could even order that the individual receive treatment, either alone or as well as other sentencing. First-time offenders specifically are often given the ability to choose a criminal justice client rehab as an alternative to other sentencing, and it is well-advised they take advantage of it if it is an alternative. The theory behind criminal justice client rehabs is that it is far 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 method is on recidivism rates, i.e. if the individual returns or not to criminal justice system following treatment. The signs and indicators seem quite positive, and criminal justice clients who do experience treatment have a much better potential for remaining out of the system after rehabilitation.
