Criminal justice client rehabs are available being a significantly better option than jail time or heavy fines for many who have already been convicted of any kind of alcohol or drug related crime. For example, someone who has been found guilty of dui of drugs or alcohol may be eligible to receive rehab services for their problem as an alternative to serving time in prison. The judge may even order that the individual receive rehabilitation, either alone or together with other sentencing. First-time offenders in particular will often be given the ability to choose a criminal justice client rehab as an alternative to other sentencing, and it is highly recommended that they benefit from it when it is a choice. The idea behind criminal justice client rehabs is it is much more efficient and effective to invest effort and time into treatment than enforcement of other consequences. Much research has been completed to observe how effective this method is on recidivism rates, i.e. if the individual returns or not to criminal justice system following rehab. The signs and indicators seem quite positive, and criminal justice clients that do experience rehab have better probability of remaining out of the system after rehab.
