Criminal justice client rehabs are available as a considerably better option than incarceration or heavy fines for individuals who have been convicted of any kind of drug or alcohol related crime. By way of example, anyone who has been in prison for driving while impaired of alcohol or drugs may qualify to get treatment services for his or her problem rather than serving time in prison. The judge might order the individual receive rehabilitation, either alone or along with other sentencing. Very first time offenders in particular in many cases are given the ability to select a criminal justice client rehab as opposed to other sentencing, and it is well-advised they make the most of it when it is an option. The concept behind criminal justice client rehabs is that it is far more efficient and effective to invest effort and time into rehab than punishment. Much research has been carried out 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. All indicators seem to be quite positive, and criminal justice clients who do take part in rehab have better probability of remaining out of the judicial system after treatment.
