Criminal justice client rehabs are available as a far better option than jail time or heavy fines for individuals who have been convicted of any sort of alcohol or drug related crime. As an example, anyone who has been found guilty of driving under the influence of alcohol or drugs may be eligible to get treatment services for his or her problem instead of serving time in jail. The judge could even order the individual receive rehab, either alone or in addition to other sentencing. First time offenders specifically are often given the ability to pick a criminal justice client rehab as opposed to other sentencing, and it is highly recommended that they reap the benefits of it if it is a choice. The theory behind criminal justice client rehabs is that it is far more effective and efficient to invest effort and time into rehab than punishment. Much research has been done 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 experience rehab have better chance of remaining out of the system following rehab.
