That ignores the fact that the percentage of the population who smokes has dropped drastically from when measures were put in place. Yeah, those warnings don't stop addicts, but they totally changed the public discourse about smoking, and societal attitudes toward the habit. I don't see a reason why that wouldn't work for other harmful behaviors like social media addiction.
