Criminal justice client rehabs are available as being a significantly better option than time in jail or significant fines for those who have already been convicted of any type of drug or alcohol related crime. As an example, somebody who has been in prison for driving drunk of drugs or alcohol may be eligible to receive rehabilitation services for his or her problem as opposed to serving time in prison. The judge could even order that the individual receive rehabilitation, either alone or along with other sentencing. Very first time offenders in particular are often given the chance to select a criminal justice client rehab as opposed to other sentencing, and it is well-advised they make the most of it if it is an alternative. The idea behind criminal justice client rehabs is it is far more effective and efficient to invest time and energy into rehabilitation than punishment. Much research has been carried out to see how effective this method is on recidivism rates, i.e. if the individual returns or not to criminal justice system following treatment. The signs and indicators seem to be quite positive, and criminal justice clients who take part in rehab have better probability of remaining out of the system following rehabilitation.
