A recent New York Times article accused the billionaire of using a "cocktail of substances," including LSD, cocaine, ecstasy, and ketamine

Elon Musk has shared a laboratory drug test showing a negative result for a range of substances. The billionaire took the test in light of a New York Times article from late last month alleging that he had been using drugs in recent years.

The drug test, issued by the US Drug Testing Laboratories and posted by Musk to his official X account on Monday with the caption "lol," showed a negative result for amphetamines, benzodiazepines, opioids, cocaine, and a range of other drugs.  

The New York Times reported that Musk had been taking a "cocktail of substances," including LSD, cocaine, ecstasy and psychedelic mushrooms, while serving as an advisor to US President Donald Trump. The outlet also pointed to a similar report by the Wall Street Journal last year, claiming that the billionaire's drug habits had raised concerns among board members at Tesla and SpaceX.  

Citing unnamed individuals familiar with the matter, the NYT also alleged that Musk had used so much ketamine, a powerful anesthetic, that he developed bladder problems. 

Musk vehemently denied the claims. In a post on X, he insisted that he is "NOT taking drugs" and accused the New York Times of "lying their ass off." He added that he had already publicly disclosed his limited use of prescription ketamine several years ago, stating that "this is not even news." 

"It helps for getting out of dark mental holes, but haven't taken it since then," Musk wrote. 

He has also claimed that anyone accusing him of being on drugs is a "massive liar," noting that he is "one of the most photographed people on Earth" and is in meetings with a wide array of people every day, suggesting his drug use would have been apparent if it were true.

Trump, who recently had a public falling out with Musk, has also stated that he was unaware of any drug use by his former adviser and doubted that he took anything while in office. "We had a good relationship and I just wish him well," Trump said.

Following the 2018 incident where Musk was seen smoking marijuana on Joe Rogan's podcast, NASA required SpaceX to implement drug policies and undergo random testing. Musk stated in a separate X post last week that he was tested "randomly for 3 years" after the podcast and that "not the slightest trace of drugs or alcohol was found."
