There is no available information to confirm that Elon Musk used ketamine while in the Oval Office. It is true that he was present in the Oval Office during his role as a special government adviser under Donald Trump, there is no evidence he used ketamine there. A New York Times report alleged Musk used ketamine frequently during the 2024 campaign, sometimes daily, and that it affected his bladder. Musk responded by saying he had tried prescription ketamine years ago for depression but denied current use. No credible sources confirm drug use inside the Oval Office itself.
