Point 4 is untrue. > Where does that leave me? According to reputable studies, ketamine can be life-changing for a significant majority — as much as three-quarters — of those who take it for depression. That leaves 25 percent, like me, who are not so fortunate. > I asked John Krystal, chief of psychiatry and behavioral health at Yale-New Haven Hospital and a leading authority on ketamine use for depression, about my experience. “There is a risk that some patients will have extremely upsetting experiences during treatment [with] ketamine or psychedelics,” he said. “The experience of losing control of the form and content of their thought processes and the altered sensory experiences are, themselves, potentially traumatic experiences.”
