> If we step back and look at this rationally though, can anybody point me to any peer reviewed studies (the actual studies, not clickbait articles written based off the studies) showing that social media is anywhere near as physically harmful or addictive as cigarettes?

First thing that comes to mind, not exactly what you're asking for but still pretty clearly "physical harm": Facebook enabled the Rohingya genocide with their algorithm fueling the hatred's spread. They knew it's happening and ignored it. Yes, genocidal hatred can be spread via other means just as well (like radio in Germany, Rwanda), but that doesn't absolve Facebook from the blame, like you wouldn't be absolved if you started a radio station to spread hateful propaganda encouraging violence.
