Criminal justice client rehabs can be considered like a significantly better option than prison time or heavy fines for those who have been convicted of any type of alcohol or drug related crime. For example, anyone who has been found guilty of driving under the influence of alcohol or drugs may qualify for treatment services for their problem rather than serving time in jail. The judge might even order that the individual receive rehab, either alone or together with other sentencing. First-time offenders in particular will often be given the ability to select 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 an alternative. The concept behind criminal justice client rehabs is that it is far more efficient and effective to invest time and energy into rehabilitation than punishment. Much research has been completed to observe how effective this process is on recidivism rates, i.e. if the individual returns or not to criminal justice system following rehab. The signs and indicators appear to be quite positive, and criminal justice clients who take part in rehab have better chance of remaining out of the judicial system following rehab.
