Criminal justice client rehabs are available like a considerably better option than time in jail or heavy fines for those who have already been convicted of any sort of alcohol or drug related crime. For instance, a person who has been found guilty of dui of alcohol or drugs may be eligible to receive rehab services for their problem rather than serving time in prison. The judge may even order the individual receive treatment, either alone or as well as other consequences. First time offenders in particular in many cases are given the opportunity to pick a criminal justice client rehab as an alternative to other sentencing, and it is highly recommended they reap the benefits of it when it is a possibility. The concept behind criminal justice client rehabs is it is way more efficient and effective to invest effort and time into treatment than enforcement of other consequences. Much research has been done to find out how effective this process 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 take part in rehabilitation have a better potential for remaining out of the system after treatment.
