Criminal justice client rehabs are available like a significantly better option than time in jail or heavy fines for individuals who have been convicted of any sort of alcohol or drug related crime. As an example, a person who has been found guilty of driving while impaired of alcohol or drugs may be eligible to obtain rehab services because of their problem rather than serving time in jail. The judge could even order that the individual receive rehab, either alone or as well as other sentencing. First-time offenders specifically tend to be given the ability to go with a criminal justice client rehab rather than other sentencing, and it is well-advised that they take advantage of it when it is an option. The concept behind criminal justice client rehabs is that it is much more efficient and effective to invest time and effort into treatment than punishment. Much research has been carried out to find out how effective this approach is on recidivism rates, i.e. if the individual returns or not to criminal justice system following rehabilitation. The signs and indicators appear to be quite positive, and criminal justice clients that experience rehab have a much better probability of remaining out of the judicial system after treatment.
