Tesla CEO Elon Musk has smoked marijuana live on the web don a live web show with comedian Joe Rogan.
Musk, 47, spent two-and-a-half hours on a podcast discussing everything from artificial intelligence and its impact on humankind to flame throwers and social media.
The exchange began when Rogan told Musk about a small container he bought in Mexico which he hoped would hold joints. He then took out a large joint and lit up.
Musk said he is no fan of the drug. He said: “Weed is not helpful for productivity. There’s a reason for the word ‘stoned.’ You just sit there like a stone on weed.”
Tesla was not immediately available for comment — but investors apparently weren’t giddy over the Musk toke.
Shares of Tesla dropped 8.2 per cent in pre-market trading, to $258.40.
