Elon Musk tells staff smoking weed with Joe Rogan was 'not wise'
Elon Musk, who very publicly smoked cannabis on Joe Rogan's podcast last year, has told employees at his Space X project to just say no to drugs at work.
The Tesla billionaire has told employees that smoking pot on one of the world's most popular podcasts "was not wise" before reminding them "SpaceX maintains a drug free workplace".
"SpaceX personnel may not use or possess any controlled substance while in the workplace, and also may not be under the influence of legal or illegal drugs while at work," Musk wrote in an email to staff obtained by The Washington Post.
Musk said the way he smoked on the podcast - "with no skill" - demonstrated his lack of experience with the drug, while also making it clear that recreational marijuana use is legal in California, where the Joe Rogan Experience is based.
The email didn't mention any restrictions on smoking marijuana outside of work hours, but said anyone high at work could be disciplined.
"Anyone who appears to be inebriated or under the influence while at work is subject to drug testing and potentially other employment actions," he wrote.
The email came as NASA launched a review of SpaceX, interviewing employees at every level of the company about training, drug policies and safety procedures.
SpaceX's president and chief operating officer Gwynne Shotwell said the review was wrapping up, with the results positive overall.
"I can tell you, it has gone very well," she said. "Not that we haven't learned things, but it's gone very well."
After Musk smoked cannabis on the podcast in September last year, Tesla shares fell more than 6 per cent.
Musk looked at his phone and laughed shortly after smoking on the podcast, telling Rogan he was getting texts from friends asking why he was smoking drugs during the interview.
"I'm not a regular smoker of weed," he said.
