Elon Musk said the federal government drug tested him back in 2018 after he smoked a blunt with Joe Rogan during a podcast episode.

The 2018 appearance on “The Joe Rogan Experience” led the federal government to drug test Musk, the billionaire said Thursday while on the Canadian-American “Full Send” podcast with the NELK Boys.

“Remember when you smoked weed on Joe Rogan, did you get like a lot of backlash for that?” host Kyle Forgeard asked.

“I did get a lot of backlash cause it’s like still federally illegal,” Musk said.

“It was pretty nutty actually. I had to – well, because, you know, uh, so I had to have like random drug tests and stuff after that to prove that I’m not like a drug addict.”

“Really?” Forgeard asked.

“By who though? Who gives you the random drug tests?” co-host Aaron Steinberg asked.

“The federal government,” Musk said. “Like, because SpaceX has a federal government contract, so. And it’s still illegal federally. So like – like the SpaceX, you know, competitors were like, ‘Hey, look at – why aren’t you doing anything?’ You know, ‘Look at him smoking – just like brazenly smoking weed on Joe Rogan’s podcast.'” (RELATED: Elon Musk’s Father Has Harsh Words For His Billionaire Son)

“So they even drug test you for weed?” Forgeard asked.

“Yeah, they drug tested me for everything. Randomly. It wasn’t like ‘pick a day.’ It was like a whole year of random drug tests.”
