Criminal justice client rehabs are available being a far better option than incarceration or heavy fines for individuals who have been convicted of any kind of drug or alcohol related crime. As an example, a person who has been found guilty of driving while impaired of drugs or alcohol may qualify to obtain rehab services for their problem instead of serving time in prison. The judge may even order the individual receive treatment, either alone or together with other consequences. First time offenders specifically in many cases are given the ability to go with a criminal justice client rehab rather than other sentencing, and it is well-advised they make the most of it when it is a choice. The theory behind criminal justice client rehabs is it is way more efficient and effective to invest effort and time into rehabilitation than enforcement of other consequences. 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 who do take part in treatment have a better possibility of remaining out of the judicial system after treatment.
