Criminal justice client rehabs are available as being a considerably better option than time in jail or significant fines for those who have been convicted of any sort of drug or alcohol related crime. For example, someone who has been found guilty of driving while impaired of drugs or alcohol may qualify for rehab services for problem as an alternative to serving time in jail. The judge might even order that the individual receive rehab, either alone or in addition to other sentencing. First time offenders in particular will often be given the opportunity pick a criminal justice client rehab as an alternative to other sentencing, and it is well-advised they make the most of it if it is an alternative. The concept behind criminal justice client rehabs is it is way more efficient and effective to invest effort and time into treatment than enforcement of other consequences. Much research has been carried out to find out how effective this method 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 that take part in rehab have better probability of remaining out of the system after rehab.
