The Stop the Scroll Act would require social media platforms to display a mental health warning label every time a user accesses the site from a U.S. server. The warning must alert users to potential mental health risks associated with social media use and provide access to resources like the 988 Suicide and Crisis Lifeline. The label cannot be hidden in terms and conditions, must remain visible until a user exits the platform or acknowledges the risks, and cannot be disabled by users. The Federal Trade Commission, working with the Surgeon General, has 180 days after the bill becomes law to create detailed regulations for the warning labels and must review them every three years. Social media platforms that violate the law would face enforcement by both the FTC and state attorneys general, with civil penalties based on either the number of days of non-compliance or the number of users who did not see the required label. The bill becomes effective one year after enactment.
