Criminal justice client rehabs are available as a considerably better option than prison time or significant fines for those who have been convicted of any sort of alcohol or drug related crime. For example, somebody who has been in prison for driving while impaired of drugs or alcohol may qualify for rehabilitation services for their problem as an alternative to serving time in prison. The judge may even order that the individual receive rehabilitation, either alone or along with other sentencing. First-time offenders specifically are often given the chance 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 efficient and effective to invest time and effort into rehab than punishment. Much research has been done to find out how effective this process is on recidivism rates, i.e. if the criminal justice client returns or not to criminal justice system following rehabilitation. All indicators seem quite positive, and criminal justice clients who take part in rehabilitation have a better possibility of remaining out of the judicial system after rehabilitation.
