As Mr. Musk entered President Trump’s orbit, his private life grew increasingly tumultuous and his drug use was more intense than previously known.

Ketamine, ecstasy, magic mushrooms, and Adderall are said to be among the cocktail of drugs the billionaire was using.

Although Musk had previously mentioned using a "small amount once every other week," the billionaire X owner may have been using ketamine frequently enough on President Donald Trump 's campaign trail for the drug to start causing some health issues, according to reporting from The New York Times.
