Criminal justice client rehabs can be considered like a far better option than incarceration or significant fines for individuals who have already been convicted of any type of alcohol or drug related crime. For example, anyone who has been in prison for driving under the influence of drugs or alcohol may qualify for rehab services because of their problem instead of serving time in prison. The judge might even order that the individual receive rehab, either alone or in addition to other consequences. First time offenders specifically tend to be given the ability to select 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 concept behind criminal justice client rehabs is it is far more efficient and effective to invest time and energy into treatment than punishment. Much research has been completed to find out how effective this approach is on recidivism rates, i.e. if the individual returns or not to criminal justice system following treatment. The signs and indicators appear to be quite positive, and criminal justice clients that do take part in rehabilitation have better probability of remaining out of the system after treatment.
