On January 12, Beijing time, in response to reports that SpaceX CEO Elon Musk had taken drugs, NASA responded on Thursday that, based on the agency’s knowledge, SpaceX did not violate workplace rules on alcohol and drugs. If it violates the rules, SpaceX could lose the government contracts it receives.

In early January this year, after the media reported Musk’s long-term drug abuse, the outside world became increasingly skeptical of SpaceX’s compliance.

NASA said in a statement on Thursday: "SpaceX complies with rules regarding employee drug and alcohol abuse and has found no evidence of violations.We expect our business partners to meet all workplace safety requirements as they perform these tasks and provide services to the American people. "

NASA also said in a statement that the agency enforced and verified compliance with contract provisions related to drug- and alcohol-free workplaces with contractors.The clauses require contractors to maintain a "robust and effective" corporate culture and safety program.
