Criminal justice client rehabs can be considered as a far better option than jail time or heavy fines for individuals who have been convicted of any sort of alcohol or drug related crime. As an example, a person who has been in prison for driving under the influence of alcohol or drugs may qualify for rehabilitation services because of their problem as an alternative 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 specifically tend to be given the chance to go with a criminal justice client rehab as an alternative to other sentencing, and it is highly recommended that they benefit from it when it is an alternative. The theory behind criminal justice client rehabs is it is much more efficient and effective to invest time and effort into rehab than punishment. Much research has been done to see how effective this strategy is on recidivism rates, i.e. if the criminal justice client returns or not to criminal justice system following treatment. The signs and indicators seem quite positive, and criminal justice clients that do take part in rehabilitation have a better probability of remaining out of the judicial system following treatment.
