Tesla shares sank 6.3 to close at $263.24 after the latest events that heightened concerns over Musk's erratic management style at the electric carmaker.
He said: I think the future in where we are a space-faring civilisation out there among the stars, that is very exciting.
While sipping whisky and smoking what Rogan called a joint containing a mix of tobacco and marijuana (which is legal in California) throughout the two and a half hour podcast, Musk discussed Telsa, flame throwers, and artificial intelligence.
Later he says he does not notice any effect from the joint and claims he rarely smokes. What I'm saying is that when Musk is bad the tweets are good, and here are the best ones from today's well-deserved social media dogpile. In the first quarter of this year, the company lost Morton's predecessor, Eric Branderiz, and Susan Repo, who was treasurer and vice president of finance.
Separately, Tesla revealed that its chief accounting officer has resigned after less than a month on the job, raising further concerns about the company's leadership stability.

The boss and the player seem to have gotten their worries behind them, and have settled last seasons's tension already. After an underwhelming summer transfer window, Manchester United are looking to shake up their recruitment process.
"You probably can't do this because of stockholders, right?", Rogan asked, to which Musk nonchalantly shrugged.
"This caused me to reconsider my future", Morton said.
The company's stock was down by roughly 7 percent in early-morning trading.
Shares in Tesla fell by as much as 9% on the same day the electric vehicle maker lost two executives and its boss was filmed smoking cannabis during an interview.
The blunt usage began near the end of the interview when Rogan produced it and Musk responded by asking, "I mean, it's legal, right?"
With Tesla's stock falling to its lowest level since April, short sellers added 810,000 shares to their positions, bringing the total as of Thursday to about 32.6 million shares, according to S3 Partners, a financial technology and analytics firm. While there is no sign of such a move, Tesla released a long list of executive appointments late Friday, including that of Jerome Guillen, an eight-year Tesla veteran with experience at the German automaker Daimler, to oversee all automotive operations.
At one point, Musk described the constant barrage of ideas in his mind as a "never-ending explosion", and said he wondered as a young boy whether he might be insane because it didn't seem to happen to other people.
