Criminal justice client rehabs are available being a significantly better option than time in jail or heavy fines for those who have been convicted of any type of alcohol or drug related crime. For instance, anyone who has been found guilty of driving under the influence of alcohol or drugs may qualify to get treatment services because of their problem rather than serving time in prison. The judge might even order the individual receive rehab, either alone or as well as other consequences. First time offenders in particular in many cases are given the opportunity to select a criminal justice client rehab instead of other sentencing, and it is well-advised they take advantage of it if it is an alternative. The theory behind criminal justice client rehabs is that it is far more effective and efficient to invest time and energy into treatment than enforcement of other consequences. Much research has been carried out to discover how effective this strategy is on recidivism rates, i.e. if the individual returns or not to criminal justice system following rehabilitation. The signs and indicators appear to be quite positive, and criminal justice clients that take part in rehab have a better potential for remaining out of the judicial system after treatment.
