Criminal justice client rehabs can be considered like a considerably better option than jail time or heavy fines for individuals who have already been convicted of any kind of drug or alcohol related crime. As an example, someone who has been found guilty of driving while impaired of drugs or alcohol may be eligible to get rehab services for his or her problem as opposed to serving time in prison. The judge could even order the individual receive rehab, either alone or as well as other consequences. First time offenders in particular will often be given the ability to select a criminal justice client rehab rather than other sentencing, and it is well-advised they benefit from it if it is a choice. The theory behind criminal justice client rehabs is that it is much more effective and efficient to invest effort and time into rehabilitation than punishment. Much research has been done to find out how effective this process is on recidivism rates, i.e. if the individual returns or not to criminal justice system following rehab. All indicators seem to be quite positive, and criminal justice clients who take part in treatment have a better probability of remaining out of the judicial system following treatment.
