Criminal justice client rehabs are available as being a far better option than prison time or heavy fines for individuals who have been convicted of any sort of drug or alcohol related crime. For instance, someone who has been in prison for driving while impaired of drugs or alcohol may be eligible to receive rehabilitation services because of their problem as opposed to serving time in jail. The judge could even order the individual receive treatment, either alone or along with other consequences. First time offenders in particular are often given the chance to select a criminal justice client rehab as opposed to other sentencing, and it is highly recommended they reap the benefits of it when it is a possibility. The theory behind criminal justice client rehabs is it is far more efficient and effective to invest time and effort into rehabilitation than punishment. Much research has been done to see how effective this method is on recidivism rates, i.e. if the criminal justice client returns or not to criminal justice system following rehabilitation. All indicators appear to be quite positive, and criminal justice clients who take part in rehab have a better chance of remaining out of the system following rehabilitation.
