Musk touched on all manner of things in the interview, but he's drawing the most attention for taking a puff of a marijuana-tobacco joint handed to him by Rogan.
"There are so many rumors and problems about Tesla that we stay skeptical concerning the Tesla shares".
Marijuana is legal for medical and recreational use in California, where the interview took place.
Tesla sank more than 7% in early trading Friday, to $260 per share, after the electric-car maker revealed that its chief accountant, Dave Morton, resigned on September 4.
"I don't think you'd necessarily want to be me", he said.
"I mean, it's legal, right?" inquired a hesitant Musk.

In other women's action, No. 19 Anastasija Sevastova upset No. 7-seeded Elina Svitolina in three sets to reach the quarters. With the Spanish legend in her corner for the fortnight, Pliskova acquired another voice of positivity.
Morton, who is walking away from a $350,000 base salary and a $10 million new-hire stock grant that would vest over four years, said he believes "strongly" in Tesla and that he had no disagreements with the company's leadership or its financial reporting.
The company disclosed the departure in a regulatory filing. Musk has said he stands by his initial tweet about the company going private. "It's very hard to keep a auto company alive", Musk said. Musk floated a take-private price of $420 - roughly a 20 percent upside from the stock's levels at the time - and claimed he had the "funding secured".
Tesla shares, down just one percent after Musk's appearance on the Rogan podcast, fell another seven percent in the half hour after Morton's resignation.
And engineers are not the only culprits, Starship Technologies' food-delivery robots are sometimes kicked by members of the public, the company's cofounder told Business Insider in June.
Musk appeared on the "The Joe Rogan Experience" podcast. The report, which was published by electric car-themed news site InsideEVs, estimated that the Tesla Model 3, Model S, and Model X, were the Top 3 electric cars in the USA in August.
Musk's Twitter followers went into a frenzy following the podcast, with user @jkmcnk writing:"Elon getting high on weed and whiskey is the first reason to go long on $TSLA in a while". "It's probably not wise", said Musk discussing kicking a robot.
