Criminal justice client rehabs are available like a far better option than incarceration or heavy fines for individuals who have already been convicted of any sort of drug or alcohol related crime. For instance, somebody who has been in prison for driving while impaired of alcohol or drugs may be eligible to receive rehabilitation services for his or her problem rather than serving time in prison. The judge could even order that the individual receive rehab, either alone or as well as other sentencing. First-time offenders specifically tend to be given the chance to select a criminal justice client rehab instead of other sentencing, and it is well-advised that they benefit from it if it is an option. The theory behind criminal justice client rehabs is that it is far more efficient and effective to invest time and energy into rehab than punishment. Much research has been completed to discover how effective this method is on recidivism rates, i.e. if the individual returns or not to criminal justice system following rehabilitation. The signs and indicators appear to be quite positive, and criminal justice clients that experience rehabilitation have better chance of remaining out of the system after treatment.
