Criminal justice client rehabs can be considered as being a considerably better option than prison time or significant fines for individuals who have already been convicted of any sort of alcohol or drug related crime. For instance, a person who has been found guilty of driving drunk of drugs or alcohol may be eligible to get treatment services for his or her problem as an alternative to serving time in jail. The judge might even order that the individual receive rehabilitation, either alone or as well as 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 highly recommended they make the most of it if it is an alternative. The theory behind criminal justice client rehabs is that it is much more efficient and effective to invest time and effort into treatment than punishment. Much research has been carried out to observe how effective this method is on recidivism rates, i.e. if the individual returns or not to criminal justice system following rehabilitation. All indicators seem quite positive, and criminal justice clients that do take part in rehab have a much better chance of remaining out of the judicial system following rehabilitation.
