We have no evidence of drug use at Musk's SpaceX: NASA

US space agency NASA responded to reports claiming that billionaire Elon Musk uses drugs, saying, "[We don't] have evidence of non-compliance from SpaceX on how [it] addresses drug and alcohol free workforce regulations." This comes after The Wall Street Journal's report said Musk used drugs like LSD, cocaine and psychedelic mushrooms. Musk said he's passed several of NASA's drug tests.
