Purification Rundown, a program used by Scientology for drug rehab purposes, was investigated by the New York Press, who found that there was no peer-reviewed research about it.
Scientologists consider it the only effective way to deal with the long-term effects of drug abuse or toxic exposure. It forms the basis for drug rehabilitation and detoxification programs operated by church-affiliated groups such as Narconon, Criminon, Second Chance, and the International Academy of Detoxification Specialists. An investigation by the New York Press asked a number of independent doctors about the evidence for the Purification Rundown. Several said that no peer-reviewed research on the rundown had been published in any medical journal. The Church of Scientology is a group of interconnected corporate entities and other organizations devoted to the practice, administration and dissemination of Scientology, which is variously defined as a cult, a business or a new religious movement.
