A bipartisan group of U.S. lawmakers sent a letter to Meta CEO Mark Zuckerberg expressing concern over the company's failure to prevent illicit drug advertisements on Facebook and Instagram. The letter cites reports from The Wall Street Journal and the Tech Transparency Project that revealed numerous ads directing users to third-party services selling illegal drugs. The company continues to run these ads despite an ongoing federal investigation into Meta for facilitating drug sales. Meta commented that it works with law enforcement to combat illegal drug activity on its platforms, rejecting hundreds of thousands of ads and continuously improving its enforcement efforts.
