Criminal justice client rehabs are available as a significantly better option than prison time or heavy fines for many who have already been convicted of any kind of alcohol or drug related crime. As an example, a person who has been in prison for driving while impaired of drugs or alcohol may be eligible to receive rehabilitation services for his or her problem as an alternative to serving time in jail. The judge could even order that the individual receive rehabilitation, either alone or along with other sentencing. First time offenders in particular are often given the ability to pick a criminal justice client rehab as an alternative to other sentencing, and it is well-advised that they take advantage of it when it is a possibility. The idea behind criminal justice client rehabs is that it is far more effective and efficient to invest time and energy into rehabilitation than enforcement of other consequences. Much research has been completed to see how effective this approach is on recidivism rates, i.e. if the criminal justice client returns or not to criminal justice system following rehabilitation. All indicators seem to be quite positive, and criminal justice clients that experience rehab have a much better probability of remaining out of the system following rehabilitation.
