Musk has spoken about his prescription ketamine use in the past. Last March, he told journalist Don Lemon that he uses a “small amount” of ketamine about once every other week. The ketamine, he said, is prescribed by “an actual, real doctor.”

The New York Times defended its reporting on Elon Musk ‘s drug use, after he claimed that the publication was “lying” in its article that claimed he was, among other things, “taking so much ketamine, a powerful anesthetic, that it was affecting his bladder, a known effect of chronic use. He took Ecstasy and psychedelic mushrooms.”
