Morton, a former chief financial officer for computer-drive maker Seagate Technology Plc, joined Tesla one day before Musk tweeted that he was considering buying out some investors at US$420 a share and taking the company private.
This time, the Tesla billionaire puffed on a marijuana joint during the recording of the Joe Rogan Experience podcast. It said Morton had no disagreements with Tesla's leadership or financial reporting.
Rogan asks if he wants some, but adds that Musk probably can't because of stockholders, nearly daring him.

Musk said he had come up with preliminary designs for a supersonic, electric plane that would take off and land vertically.
"Totally legal", Rogan responded, handing Musk the joint.

Tesla Chief Accounting Officer Dave Morton resigned Tuesday, according to a Tesla public filing Friday morning.
Today it was revealed that two top executives have left Tesla, and its plummeting stock fell even lower. The stock has plunged 31 percent since Musk floated the idea of taking the vehicle maker off the public market, lopping billions of dollars off the company's market value.
