The CEO of Tesla and Space X smoked marijuana toward the end of a more than two-and-half-hour live interview Thursday on comedian Joe Rogan's podcast, the Joe Rogan Experience.
The conversation touched on everything from flamethrowers to artificial intelligence.
"I think I tried one once," said Musk, when asked if he had ever smoked a mix of weed and tobacco.
"I mean, it's legal right?"
Musk then took a single puff from the joint offered by Rogan.
The interview was filmed in Los Angeles, where marijuana is legal under state law.
