Criminal justice client rehabs can be considered as a considerably better option than incarceration or heavy fines for individuals who have already been convicted of any sort of alcohol or drug related crime. For instance, someone who has been found guilty of driving while impaired of drugs or alcohol may be eligible to receive rehabilitation services for their problem as opposed to serving time in jail. The judge might even order the individual receive rehabilitation, 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 opposed to other sentencing, and it is well-advised that they benefit from it when it is a choice. The concept behind criminal justice client rehabs is that it is far more effective and efficient to invest time and energy into treatment than enforcement of other consequences. Much research has been done to find out how effective this method is on recidivism rates, i.e. if the criminal justice client returns or not to criminal justice system following rehabilitation. The signs and indicators appear to be quite positive, and criminal justice clients who do experience rehab have better chance of remaining out of the judicial system after rehab.
