Criminal justice client rehabs are available as a far better option than time in jail or heavy fines for many who have already been convicted of any sort of alcohol or drug related crime. By way of example, anyone who has been found guilty of dui of drugs or alcohol may be eligible to receive rehab services for his or her problem instead of serving time in jail. The judge might even order that the individual receive rehabilitation, either alone or along with other sentencing. First time offenders in particular tend to be given the opportunity to go with a criminal justice client rehab as an alternative to other sentencing, and it is highly recommended they reap the benefits of it if it's an option. The theory behind criminal justice client rehabs is it is way more efficient and effective to invest time and effort into rehab than punishment. Much research has been completed to observe how effective this approach is on recidivism rates, i.e. if the criminal justice client returns or not to criminal justice system following rehab. The signs and indicators appear to be quite positive, and criminal justice clients that do experience rehabilitation have better potential for remaining out of the system after treatment.
