Elon Musk said he had to take drug tests for a year after smoking weed on Joe Rogan's podcast in 2018. "I don't even know how to smoke a joint," the tech billionaire told the "Full Send" podcast Thursday. "I had to have like random drug tests and stuff after that, to prove that I'm not like a drug addict," Musk said, adding that the tests were required by the federal government. I had like a whole year of random drug tests." "Unfortunately, it wasn't just me but the whole company, the whole of SpaceX had to have random drug tests," Musk continued.
