Social media platforms must display black box warnings when users first access the platform, exit, and after three hours of use (then hourly), with warnings covering 25-75% of the screen and lasting 10-90 seconds depending on the trigger.

Platforms must monitor users for "problematic behaviors" including more than three hours of daily use, accessing the platform within 10 minutes of waking, or making 10+ posts per day, and provide mental health resources when detected.

All warnings must include text stating the Surgeon General has warned that social media "is associated with significant mental health harms and has not been proven safe for young users."

Advertisements for social media platforms must be factual, not misleading, and include disclaimers about potential negative mental health impacts based on federal and state health department findings.

Violations carry civil penalties up to $250,000 per offense, with the law taking effect six months after enactment.
