Criminal justice client rehabs can be considered as being a significantly better option than incarceration or heavy fines for those who have already been convicted of any sort of alcohol or drug related crime. For example, anyone who has been found guilty of dui of alcohol or drugs may qualify for treatment services because of their problem as opposed to serving time in jail. The judge might order the individual receive rehabilitation, either alone or along with other sentencing. First time offenders specifically will often be given the chance to select a criminal justice client rehab as an alternative to other sentencing, and it is well-advised that they benefit from it if it is an option. The theory behind criminal justice client rehabs is that it is way more efficient and effective to invest effort and time into rehabilitation than punishment. Much research has been completed to find out how effective this strategy is on recidivism rates, i.e. if the criminal justice client returns or not to criminal justice system following treatment. The signs and indicators appear to be quite positive, and criminal justice clients who experience rehabilitation have better probability of remaining out of the judicial system after treatment.
