Tesla founder Elon Musk hit back at claims made in a shocking Wall Street Journal report over the weekend that alleged board members at his companies were alarmed by his drug use.

Early Monday, Musk responded to the report in a post on his social media platform, X.

‘TMZ has vastly higher standards than the WSJ (actually),’ Musk wrote, an apparent jab at the broadsheet Wall Street Journal by comparing it to TMZ, a website that specializes in salacious gossip.

Speaking to the Journal, Musk’s attorney, Alex Spiro, said that the South African was ‘regularly and randomly drug tested at SpaceX and has never failed a test.’

The article alleges that Musk’s drug of choice is ketamine, a dissociative anesthetic that can produce hallucinogenic effects.

In 2018, Musk is believed to have caused shares in Tesla to crash when he openly smoked marijuana with controversial podcaster Joe Rogan during an appearance on his show. The show was recorded in California, where cannabis is legal.

However, witnesses told the Journal that the X owner has also used LSD, cocaine, ecstasy and psychedelic mushrooms, often at private exclusive parties around the world where guests have to sign NDAs and hand in their phones to avoid photos being taken.

In 2018, for example, he took multiple tabs of acid at a party he hosted in Los Angeles, the Journal reported.

The next year he allegedly consumed magic mushrooms at an event in Mexico and in 2021 took ketamine recreationally with his brother at a house party in Miami.

The billionaire has even taken drugs with current SpaceX and former Tesla board member Steve Jurvetson, according to the Journal.

Those close to the 52-year-old are now reportedly concerned that the extent of his drug taking could cause of health crisis or a crisis for his businesses.

SpaceX is the only U.S. company now approved to transport NASA astronauts to and from the International Space Station.

However, illegal drug use would likely be a violation of federal policies that could jeopardize SpaceX’s billions of dollars in government contracts.

Musk’s drug use and the volatile behavior it can exacerbate has already led to resignations at the top of Musk’s businesses, the Journal reports.

Linda Johnson Rice, a former Tesla director, allegedly became increasingly concerned with Musk’s drug taking and so frustrated with his behavior that she didn’t stand for re-election to the company’s board in 2019, people familiar with the matter told the publication.

Serious concerns over Musk’s drug taking were raised in 2017 when at a SpaceX meeting about the Big Falcon Rocket prototype Musk was slurring his words and rambled somewhat incomprehensibly for fifteen minutes, according the the Journal’s sources.

SpaceX President Gwynne Shotwell reportedly stepped in and took over the meeting.

After the meeting SpaceX executives reportedly talked privately about their concerns that Musk was on drugs.

One described told the Journal the event was ‘nonsensical,’ ‘unhinged’ and ‘cringeworthy.’

Just last week a US labor agency accused SpaceX of unlawfully firing employees who penned an open letter critical of CEO Elon Musk and creating an impression that worker activities were under surveillance by the rocket ship company.

A Los Angeles-based regional director for the National Labor Relations Board on Wednesday filed a complaint that consolidates eight unfair labor practice charges against SpaceX.

The cases stem from the company’s alleged actions following the circulation of the employees’ letter back in June 2022.

The letter, among other workplace concerns, called on executives to condemn Musk’s public behavior on X — the platform then-known as Twitter — and hold everyone accountable for unacceptable conduct.

Musk’s actions included making light of sexual harassment allegations against him, which the billionaire denied.

‘As our CEO and most prominent spokesperson, Elon is seen as the face of SpaceX — every tweet that Elon sends is a de facto public statement by the company,’ the open letter said at the time.

The letter also referred to Musk’s actions as a ‘frequent source of distraction and embarrassment.’

A total of nine employees were soon terminated for their involvement in the letter, according to a November 2022 filing made on behalf of one of the employees to the NLRB, although only eight are included in Wednesday’s complaint.
