Criminal justice client rehabs can be considered being a far better option than incarceration or heavy fines for many who have been convicted of any type of drug or alcohol related crime. For instance, anyone who has been in prison for driving while impaired of drugs or alcohol may qualify to get rehab services for his or her problem rather than serving time in prison. The judge could even order that the individual receive treatment, either alone or as well as other sentencing. First time offenders in particular will often be given the chance to go with a criminal justice client rehab rather than other sentencing, and it is highly recommended they take advantage of it if it is an alternative. The theory behind criminal justice client rehabs is that it is far more effective and efficient to invest effort and time into rehabilitation than punishment. Much research has been completed to discover how effective this method is on recidivism rates, i.e. if the criminal justice client returns or not to criminal justice system following treatment. All indicators seem to be quite positive, and criminal justice clients who do experience rehabilitation have better probability of remaining out of the judicial system after rehab.
