A study published in the prestigious medical journal The Lancet, which concluded that taking painkillers could protect against oral cancer, has been exposed as being based entirely on fabricated data. "He faked everything: names, diagnosis, gender, weight, age, drug use. There is no real data whatsoever, just figures he made up himself. Every patient in this paper is a fake," Stein Vaaler, the director of strategy at the hospital, told the Guardian.
