Criminal justice client rehabs can be considered like a far better option than incarceration or heavy fines for those who have been convicted of any sort of drug or alcohol related crime. As an example, a person who has been found guilty of driving under the influence of drugs or alcohol may qualify to get rehabilitation services because of their problem as an alternative to serving time in jail. The judge may even order that the individual receive rehab, either alone or together with other consequences. First-time offenders specifically are often given the opportunity to select a criminal justice client rehab as an alternative to other sentencing, and it is well-advised they take advantage of it when it is a choice. The idea behind criminal justice client rehabs is that it is far more efficient and effective to invest effort and time into rehabilitation than punishment. Much research has been completed to see 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 seem quite positive, and criminal justice clients that do take part in treatment have a better possibility of remaining out of the system after treatment.
