The U.S. surgeon general has called on Congress to require warning labels on social media platforms similar to those now mandatory on cigarette boxes.

In a Monday opinion piece in the The New York Times, Dr. Vivek Murthy said that social media is a contributing factor in the mental health crisis among young people.

“It is time to require a surgeon general’s warning label on social media platforms, stating that social media is associated with significant mental health harms for adolescents. A surgeon general’s warning label, which requires congressional action, would regularly remind parents and adolescents that social media has not been proved safe,” Murthy said. “Evidence from tobacco studies show that warning labels can increase awareness and change behavior.”
