Elon Musk has frequently found himself in media headlines; of late, advertisers have pulled out of X as they try to distance themselves from Musk following his endorsement of an antisemitic post. Now, a Wall Street Journal report alleges that Musk has used illegal drugs at private parties for years, and it is concerning executives at SpaceX and Tesla.

As a 2018 clip of Musk legally smoking marijuana on Joe Rogan’s podcast, “the Joe Rogan Experience,” was viewed by millions of people, widespread criticism poured in.

NASA was not thrilled; the agency demanded to know if SpaceX, the only contractor given the green light to take astronauts to the International Space Station, was a drug-free workplace.

Musk wrote an apology and agreed to random drug testing.
