Criminal justice client rehabs are available as a far better option than time in jail or heavy fines for those who have already been convicted of any type of alcohol or drug related crime. For example, somebody who has been in prison for driving under the influence of alcohol or drugs may qualify to get treatment services for their problem rather than serving time in jail. The judge could even order that the individual receive rehabilitation, either alone or in addition to other sentencing. First time offenders in particular in many cases are given the ability to go with a criminal justice client rehab instead of other sentencing, and it is highly recommended that they benefit from it when it is an alternative. The idea behind criminal justice client rehabs is that it is way more effective and efficient to invest time and effort into rehab than punishment. Much research has been done to observe how effective this method is on recidivism rates, i.e. if the criminal justice client returns or not to criminal justice system following rehab. The signs and indicators seem to be quite positive, and criminal justice clients who experience treatment have a better probability of remaining out of the system following rehabilitation.
