    What to Know About the Effects of Ketamine

    Elon Musk has said that he used ketamine as a treatment in the past, but he denied reports that he was taking it frequently and recreationally.News reports detailing Elon Musk’s drug use have prompted renewed attention to ketamine, a powerful anesthetic that has become increasingly popular as a therapy for treatment-resistant depression and other mental health issues.Although Mr. Musk has acknowledged using ketamine in the past to treat depression, he has denied suggestions that he is currently using ketamine — or any other drug.“I am NOT taking drugs!” he wrote last week in a social media post following the publication of an article in The New York Times that described reports of his use of drugs on the campaign trail last year. Those drugs included ketamine and other psychedelic compounds, among them MDMA and psilocybin mushrooms.Mr. Musk left the White House last week. Since then, he and President Trump have traded barbs on social media over the president’s domestic policy bill and have mentioned government contracts with Mr. Musk’s companies and Mr. Musk’s relationship to the White House.Mr. Trump, who was briefed on the article in The Times, has been telling associates in the last day or so that Musk’s “crazy” behavior is linked to his drug use, according to a Times report citing two people with knowledge of Mr. Trump’s private conversations. But later on Friday, Mr. Trump told reporters he did not want to comment on Mr. Musk’s drug use.The very public feud between the two men has once again drawn unflattering attention to ketamine, a drug that has become increasingly available at legal clinics across the country. It is also used recreationally and can be dangerous when misused.We are having trouble retrieving the article content.Please enable JavaScript in your browser settings.Thank you for your patience while we verify access.

    Trump Has Options to Punish Musk Even if His Federal Contracts Continue

    The president could tighten federal oversight of the tech titan’s businesses, even if heavy reliance by the Pentagon and NASA on them makes terminating Mr. Musk’s contracts less feasible.After the relationship between President Trump and Elon Musk exploded into warfare Thursday, Mr. Trump suggested that he might eliminate the tech titan’s federal contracts.“The easiest way to save money in our Budget, Billions and Billions of Dollars, is to terminate Elon’s Governmental Subsidies and Contracts. I was always surprised that Biden didn’t do it,” Mr. Trump posted on his social media platform.That’s not as easy as Mr. Trump implies. The Pentagon and NASA remain intensely reliant on SpaceX, Mr. Musk’s rocket launch and space-based communications company, to get to orbit and move government data across the world.But there are options available to the president that could make Mr. Musk’s relationship with the federal government much more difficult than it has been so far in Mr. Trump’s second administration.Mr. Trump’s most accessible weapon to punish Mr. Musk is the ability to instruct federal regulators to intensify oversight of his business operations, reversing a slowdown in regulatory actions that benefited Mr. Musk’s businesses after Mr. Trump was elected.“In an administration that has defined itself by reducing regulation and oversight, it would not be difficult to selectively ramp up oversight again,” said Steven L. Schooner, a former White House contracts lawyer who is now a professor at George Washington University.We are having trouble retrieving the article content.Please enable JavaScript in your browser settings.Thank you for your patience while we verify access.

    If Elon Musk and Donald Trump Make Up, Don’t Be Surprised

    For all the insults that Mr. Musk and Mr. Trump traded on Thursday, don’t be surprised if they make up again days from now. In the meantime, they both benefit.Elon Musk was once known for doing things. The entrepreneur reached a new peak of fame on Thursday for saying things. It was mostly bad things about President Trump.The spat was revelatory, it was epic, it was historic, at least according to the thousands of earnest and excited commentaries that were instantly published.It was also a well-timed outburst.Mr. Musk and Mr. Trump did not have a feud five days ago and might not have a feud five days from now. Until proven otherwise, all of this is theater. Think of it as the political version of professional wrestling. For a few hours, everyone was diverted by the spectacle of a brawl between the world’s richest man and its most powerful person.Mr. Trump took a break from tariffs and deportations. For Mr. Musk, the episode was even more valuable. His wealth comes from the promise that Tesla, his electric car company, will own a significant slice of the self-driving future. The launch of Tesla’s robotaxi business is next week in Austin. Skepticism abounds. The more attention it gets, the bigger a disappointment it could be.Mr. Musk’s SpaceX business is even more problematic. For all its promise to set up colonies on Mars, it is having trouble with the basics. The ninth flight test of SpaceX’s Starship program a few days ago saw both the reusable booster exploding and, 40 minutes later, the rocket itself blowing up. It wasn’t the first such failure either.SpaceX, which is owned by Mr. Musk, left, is having trouble with the basics of spaceflight.

    How NASA Would Struggle Without SpaceX if Trump Cancels Musk’s Contracts

    If President Trump cancels the contracts for Elon Musk’s private spaceflight company, the federal government would struggle to achieve many goals in orbit and beyond.In 2006, a small, little-known company named Space Exploration Technologies Corporation — SpaceX, for short — won a NASA contract to ferry cargo and supplies to the International Space Station.At that moment, SpaceX had not yet launched anything to orbit and would not succeed until two years later with its tiny Falcon 1 rocket. But since then, the Elon Musk-founded company has become the linchpin of all American civilian and military spaceflight.It started in 2010 with the launch of the first Falcon 9 rocket. By 2012 the launcher was sending cargo to the space station.NASA money helped finance the development of the Falcon 9, and SpaceX capitalized on the NASA seal of approval to entice companies to launch their satellites with SpaceX.It became the Southwest Airlines of the rocket industry, selling launches and hauling satellites into orbit at a lower price than most other rockets then available.That story repeated during the Obama administration when SpaceX won a contract to take astronauts to the space station, which it did for the first time in May 2020 during the first administration of President Trump.We are having trouble retrieving the article content.Please enable JavaScript in your browser settings.Thank you for your patience while we verify access.

    Donald Trump and Elon Musk’s Fight Brings the Memes Out in Full Force

    What happens when two billionaires with huge followings on social media start a public feud? Great memes.It was a messy divorce, and the internet was watching from the sidelines. So of course, the memes were out in full force.As the relationship between President Trump and Elon Musk unraveled publicly on Thursday, bystanders flooded social media with memes comparing them to the main figures in some of the most legendary feuds, including the teenage frenemies of “Mean Girls” and the rappers Drake and Kendrick Lamar.“The big beautiful bill led to the big beautiful breakup,” one person observed on X, Mr. Musk’s social media platform, referring to the disagreement over Mr. Trump’s domestic policy bill that set off the clash. An X account devoted to political jokes posted a doctored image of an iPhone emergency alert: “THE GIRLS ARE CRASHING OUTTTTT,” it announced.It’s “like Kendrick v. Drake but with two Drakes,” another X user posted, comparing Mr. Trump and Mr. Musk to the rapper who was perceived as having definitively lost his feud with Mr. Lamar after Mr. Lamar performed a diss track at the Super Bowl in February.Other scenarios recast Mr. Trump and Mr. Musk as a divorced couple sharing custody of their child, Vice President JD Vance; supermarket lobsters being egged on to fight; and two monkeys engaged in a knife fight surrounded by cheering spectators clutching fistfuls of money — a scene from a 2000 episode of “The Simpsons.”We are having trouble retrieving the article content.Please enable JavaScript in your browser settings.Thank you for your patience while we verify access.

    Germans Are Buying More Electric Cars, but Not Teslas

    Drivers in the country, Europe’s largest car market, are avoiding vehicles from Tesla, which has seen a drop in sales in other countries as well.Tesla sales in Germany dropped in May for the fifth month in a row, as demand for the electric vehicle maker continued to slide across much of Europe, despite Elon Musk’s efforts to turn his focus away from his U.S. government activities and back to his companies.Registrations of new Tesla cars in Germany, Europe’s largest car market, dropped more than a third from the same month last year, data released by the country’s Federal Motor Transport Authority, K.B.A., showed on Wednesday.Tesla sales in other European countries have also remained depressed, falling more than 67 percent in France and 29 percent in Spain in May.Only Norway stood out as an exception, with Tesla selling 2,600 cars in May, more than triple the number sold a year earlier. Sales were led by deliveries of Tesla’s newly revamped version of its most popular vehicle, the Model Y.In neighboring Sweden, Volkswagen sold nearly twice as many of its latest electric model, the ID.7, as the new Model Y from Tesla, whose overall sales in the country dropped 53 percent.Mr. Musk has tried to downplay the extent of Tesla’s losses in Europe, telling Bloomberg News in an interview at the Qatar Economic Forum that although it was the region where the brand faces its greatest challenges, “the European car market is quite weak.”But data from European markets does not support that claim. In Germany, sales of battery-powered cars grew nearly 45 percent in May, compared with a year earlier. In Spain, overall sales of electric cars grew 72 percent, while Tesla sales slid 19 percent.In Germany, demand for BYD, Tesla’s main E.V. rival, rose ninefold, the strongest showing of an electric vehicle producer from China. The company, which overtook Tesla as the world’s top seller of electric cars this year, has been making inroads in Europe, despite facing tariffs of 17 percent imposed by the European Union in 2024.Although Mr. Musk has left his role at the White House, Tesla sales have been affected by his foray into politics. In April, the company reported that its vehicle sales fell 13 percent in the first quarter from a year earlier, as profit plunged to its lowest level in four years.The company has been hurt by protests against Mr. Musk’s support for President Trump and several far-right parties in France, Germany and Italy.

    Some House Republicans Have Regrets After Passing Trump’s Domestic Policy Bill

    The sprawling legislation carrying President Trump’s domestic agenda squeaked through the House with one vote to spare, but some Republicans now say they didn’t realize what they voted for.When Republicans muscled their sweeping domestic policy bill through the House by a single vote after an overnight debate, they breathed a sigh of relief, enjoyed a celebratory moment at sunrise and then retreated to their districts for a weeklong recess.Not even two weeks later, the victory has, for some, given way to regret.It turns out that the sprawling legislation to advance tax and spending cuts and to cement much of President Trump’s domestic agenda included a raft of provisions that drew little notice or debate on the House floor. And now, Republicans who rallied behind the bill are claiming buyer’s remorse about measures they swear they did not know were included.Last week, Representative Mike Flood of Nebraska admitted during a town hall meeting in his district that he did not know that the bill would limit judges’ power to hold people in contempt for violating court orders. He would not have voted for the measure, he said, if he had realized.And as lawmakers returned to Washington on Tuesday after their weeklong break, Representative Marjorie Taylor Greene of Georgia said that she had been unaware that the mega-bill she voted for would block states from regulating artificial intelligence for a decade.“Full transparency, I did not know about this section,” Ms. Greene posted on social media, calling it a violation of states’ rights and adding that she “would have voted NO if I had known this was in there.”The remorseful statements highlighted the realities of legislating in the modern age. Members of Congress, divided bitterly along partisan lines and often working against self-imposed political deadlines, have become accustomed to having their leaders throw together huge pieces of legislation at the very last moment — and often do not read the entirety of the bill they are voting on, if they read any of it at all. At the same time, the polarization of Congress means that few pieces of legislation make it to the floor or to enactment — and the few “must pass” bills that do are almost always stuffed full of unrelated policy measures that would otherwise have little hope of passing on their own.We are having trouble retrieving the article content.Please enable JavaScript in your browser settings.Thank you for your patience while we verify access.
