Criminal justice client rehabs are available like a far better option than prison time or heavy fines for those who have already been convicted of any type of drug or alcohol related crime. As an example, anyone who has been found guilty of driving drunk of drugs or alcohol may be eligible to receive rehab services for their problem as opposed to serving time in jail. The judge might even order that the individual receive rehabilitation, either alone or along with other sentencing. New offenders specifically are often given the ability to choose a criminal justice client rehab rather than other sentencing, and it is well-advised that they reap the benefits of it if it's a possibility. The theory behind criminal justice client rehabs is it is much more efficient and effective to invest effort and time into rehabilitation than enforcement of other consequences. Much research has been carried out to see how effective this process is on recidivism rates, i.e. if the individual returns or not to criminal justice system following rehab. The signs and indicators seem to be quite positive, and criminal justice clients that do experience rehab have better chance of remaining out of the system after rehabilitation.
