Criminal justice client rehabs can be considered being a considerably better option than time in jail or significant fines for those who have already been convicted of any kind of alcohol or drug related crime. By way of example, anyone who has been in prison for driving drunk of alcohol or drugs may be eligible for rehabilitation services because of their problem rather than serving time in prison. The judge may even order the individual receive rehab, either alone or along with other sentencing. New offenders specifically will often be given the opportunity select a criminal justice client rehab instead of other sentencing, and it is well-advised that they benefit from it when it is a choice. The theory behind criminal justice client rehabs is that it is much more effective and efficient to invest time and energy into rehab than punishment. Much research has been carried out to see how effective this approach is on recidivism rates, i.e. if the criminal justice client returns or not to criminal justice system following rehabilitation. The signs and indicators seem quite positive, and criminal justice clients that take part in rehab have a better possibility of remaining out of the system following treatment.
