Criminal justice client rehabs are available as being a far better option than incarceration or heavy fines for individuals who have already been convicted of any sort of drug or alcohol related crime. As an example, anyone who has been found guilty of dui of alcohol or drugs may be eligible for treatment services for his or her problem as opposed to serving time in prison. The judge might even order the individual receive rehabilitation, either alone or together with other consequences. First-time offenders specifically in many cases are given the ability to choose a criminal justice client rehab rather than other sentencing, and it is well-advised that they take advantage of it if it's an option. The concept behind criminal justice client rehabs is it is far more efficient and effective to invest effort and time into rehab than enforcement of other consequences. Much research has been done to observe how effective this approach is on recidivism rates, i.e. if the individual returns or not to criminal justice system following rehabilitation. All indicators seem to be quite positive, and criminal justice clients who take part in rehabilitation have better potential for remaining out of the system following rehabilitation.
