Criminal justice client rehabs are available as being a considerably better option than prison time or heavy fines for those who have been convicted of any sort of alcohol or drug related crime. As an example, somebody who has been found guilty of driving under the influence of drugs or alcohol may qualify to get rehabilitation services for his or her problem as opposed to serving time in jail. The judge could even order that the individual receive rehabilitation, either alone or together with other consequences. First time offenders in particular are often given the ability to pick a criminal justice client rehab rather than other sentencing, and it is well-advised that they take advantage of it if it is an alternative. The idea behind criminal justice client rehabs is it is far more effective and efficient to invest effort and time into rehab than punishment. Much research has been done to find out how effective this approach is on recidivism rates, i.e. if the individual returns or not to criminal justice system following treatment. The signs and indicators seem to be quite positive, and criminal justice clients who take part in treatment have better chance of remaining out of the judicial system after rehab.
