Tesla and SpaceX CEO Elon Musk, known for his often erratic behavior, is under scrutiny following recent reports alleging drug use and its possible effects on his companies. In his recent interview with journalist Don Lemon, Musk defended his use of ketamine, a prescription anaesthetic and a hallucinogen, saying he takes only a small amount every week on advice of a doctor. "There are times when I have sort of a ... negative chemical state in my brain, like depression I guess, or depression that's not linked to any negative news, and ketamine is helpful for getting one out of the negative frame of mind," Musk told Lemon.
The billionaire entrepreneur said he used only "a small amount once every other week or something like that" under medical supervision and has a prescription from "an actual, real doctor."
