Musk's rip on Joe Rogan's show is still making news because he keeps talking about it.
According to the billionaire, the federal government began to administer random drug tests on him after he was filmed smoking a fatjoint.
Musk said that he had to have random drug tests after that to prove that he wasn't a drug user.
According to Musk, it was his companies' competitors that put the government up to it.
The competitors were asking why they weren't doing something. "Look at him smoking weed on Joe Rogan's show," Musk said.
He claimed that the entire company had to have random drug tests.
It's not unusual for a company with large grants from the US government to maintain a drug-free workplace.
The law that requires random drug testing is enforced by the Department of Health's Substance Abuse and Mental Health Services Administration.
Musk said in the interview that people shouldn't be imprisoned for cannabis or other non-violent drug crimes, and joked about how bad he was at smoking pot.
He did not know how to smoke a joint. I don't have smoking skills.
There was no argument from us there.
There are rumors that Musk is building his own airport.
