Erick Turner, a psychiatry professor at the Oregon State Health and Sciences University, woke up one day and realized that he was acting as a shill for pharmaceutical corporations. Worse, he was promoting drugs that not only provide very little benefit, but also do great harm. In spite of the benefits paid to him, including accommodations and thousands of dollars, and the ego satisfaction of being recognized as a "Very Important Person" by his fellow physicians, his conscience wouldn't let him continue.
So, Dr. Turner turned on his pharmaceutical masters. He spoke out against the products he'd been promoting. In the January 2008 issue of the New England Journal of Medicine, he published an article telling the truth about one class of drugs, SSRI antidepressants, such as Prozac and Paxil. In interviews, he has spoken even more broadly, stating that the lack of efficacy of SSRIs is the "dirty little secret" of the psychiatric world.
