But even the notion of a marijuana-smoking chief executive seemed less disturbing to Tesla watchers than the departure of Dave Morton, the accounting chief, whose immediate resignation was reported Friday in a securities filing.
And the stock dropped more than 6 per cent Friday to close at $263.24 a share - its lowest point since April.
Musk stunned investors a month ago with tweets saying he had funding to take the company private for $420 per share. "As a result, this caused me to reconsider my future", Morton said in the filing.
Overall, Morton appears to have parted ways with Tesla amicably, stating that he still believes in the company's overall mission, as well as its future prospects.
"I think you have a responsibility as a CEO to be a role model to young kids and kids in college and young executives, to your employees", Sun Microsystems co-founder Scott McNealy said on Friday during an interview on FOX Business' "Cavuto: Coast to Coast". "I don't actually notice any effect. I don't find that it is very good for productivity".
Tesla did not immediately respond to a request for comment. She wouldn't give a reason for her departure, which she said has been in the works for two months. "Maybe he is the best Chief Marketing Officer and Tesla needs a strong new CEO", analyst Frank Schwope at NORD/LB said.

Federal prosecutors with the special counsel's office had asked Judge Randolph Moss for a sentence of up to six months in prison. CNN plans to air the full interview with Papadopoulos at 11 pm on Friday. "We don't talk politics", he said.
Musk told Rogan that running Tesla is the hardest of his several endeavors.
Long a polarizing figure because of his swashbuckling style, Musk is seen by his champions as an entrepreneurial genius with the potential to remake the transportation system, while his detractors see him as an egotistical blowhard whose outsized promises have driven unjustified gains in the company's values.
The turnover among top executives should concern investors who wanted more stability at Tesla, said John Wilson, head of research and corporate governance at Cornerstone Capital Group.
Late Wednesday night, Musk smoked marijuana and drank whiskey on a livestreamed podcast interview with comedian Joe Rogan in Los Angeles, where marijuana is legal. Guillen, whom Musk says was a key player in the construction of an additional Model 3 assembly line in a tent adjacent to the factory, will report directly to Musk and oversee all automotive and supply chain operations.
Tesla is under extreme pressure to turn a sustained net profit starting this quarter, as promised by Mr Musk.
"It's marijuana inside of tobacco", Rogan replied, and he asked if Musk had ever had it.
