Criminal justice client rehabs are available as being a considerably better option than time in jail or significant fines for individuals who have been convicted of any kind of drug or alcohol related crime. For example, anyone who has been in prison for driving while impaired of drugs or alcohol may qualify to obtain rehabilitation services for his or her problem rather than serving time in prison. The judge may even order that the individual receive rehab, either alone or in addition to other sentencing. First-time offenders in particular are often given the opportunity to pick a criminal justice client rehab as opposed to other sentencing, and it is well-advised they make the most of it when it is a choice. The concept behind criminal justice client rehabs is it is far more effective and efficient to invest time and energy into rehabilitation than punishment. Much research has been done to see how effective this approach is on recidivism rates, i.e. if the individual returns or not to criminal justice system following rehabilitation. All indicators appear to be quite positive, and criminal justice clients that do experience rehabilitation have a much better probability of remaining out of the system after rehab.
