He’s the only GOP presidential candidate on TikTok, but entrepreneur Vivek Ramaswamy is talking about teens staying away from “addictive social media.”

In a question about security, Ramaswamy pivoted to a discussion of border security, talking about teens turning to social media like Snapchat to procure pharmaceuticals.

“If you’re 16 years old or under, you should not be using an addictive social media product, period,” he said.

Ramaswamy, who at 38 is the youngest candidate on stage, has referred to TikTok as “digital fentanyl” but earlier this month joined the platform, with his campaign saying he was angling to appeal to younger voters.

The platform has been met with bipartisan criticism that it is a potential spy mechanism for China.
