Criminal justice client rehabs can be considered being a significantly better option than jail time or heavy fines for individuals who have been convicted of any type of alcohol or drug related crime. By way of example, a person who has been found guilty of dui of drugs or alcohol may be eligible to obtain rehabilitation services for their problem instead of serving time in prison. The judge could even order the individual receive treatment, either alone or along with other consequences. First time offenders specifically will often be given the opportunity choose a criminal justice client rehab rather than other sentencing, and it is well-advised they take advantage of it if it is an alternative. The theory behind criminal justice client rehabs is that it is far more efficient and effective to invest time and energy into rehabilitation than enforcement of other consequences. Much research has been done to find out how effective this method 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 do take part in rehab have a much better potential for remaining out of the system following treatment.
