Criminal justice client rehabs are available as being a significantly better option than jail time or heavy fines for individuals who have been convicted of any sort of alcohol or drug related crime. For instance, anyone who has been found guilty of driving under the influence of drugs or alcohol may qualify to obtain rehab services for his or her problem as opposed to serving time in jail. The judge may even order the individual receive rehab, either alone or as well as other sentencing. First-time offenders specifically will often be given the opportunity to go with a criminal justice client rehab as an alternative to other sentencing, and it is well-advised they reap the benefits of it if it is an option. The concept behind criminal justice client rehabs is it is far more effective and efficient to invest time and energy into treatment than punishment. 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 take part in rehab have a better probability of remaining out of the system after treatment.
