The "Social Media Public Service Announcement and Youth Mental Health Act" aims to address the mental health challenges faced by children and adolescents due to social media use in South Carolina. The bill mandates that social media platforms operating in the state display public service announcements (PSAs) created by the Office of Mental Health, which will inform users about the dangers of social media, including risks of anxiety, depression, and cyberbullying. Specifically, for every ten pieces of content displayed on a user's feed, one PSA must be shown. The Office of Mental Health is responsible for providing the PSA content and guidelines, and social media platforms are prohibited from altering this content.

Additionally, the bill establishes reporting requirements for social media platforms, which must submit annual compliance reports detailing user impressions of the PSA content and any challenges faced in implementation. Noncompliance can result in significant penalties, with fines of up to $25,000 per day for violations, which will be directed to a newly created Youth Mental Health Awareness Fund. The act also allows the Department of Behavioral Health and Developmental Disabilities to create necessary regulations for enforcement. The law is set to take effect on January 1, 2027.
