Criminal justice client rehabs can be considered as being a far better option than time in jail or significant fines for individuals who have been convicted of any kind of drug or alcohol related crime. As an example, somebody who has been found guilty of driving drunk of alcohol or drugs may be eligible to obtain rehab services because of their problem rather than serving time in prison. The judge could even order that the individual receive rehabilitation, either alone or along with other sentencing. First time offenders in particular are often given the opportunity to select a criminal justice client rehab rather than other sentencing, and it is highly recommended they take advantage of it when it is an alternative. The theory behind criminal justice client rehabs is that it is much more efficient and effective to invest commitment into rehabilitation than punishment. Much research has been done to find out how effective this method is on recidivism rates, i.e. if the criminal justice client returns or not to criminal justice system following rehab. All indicators seem to be quite positive, and criminal justice clients that take part in rehabilitation have a better probability of remaining out of the judicial system following treatment.
