Agree about the history of obfuscation on the dangers of things in the past and seemingly the present. Also agree that makes sense be a little skeptical of industry supported research as you suggest.
Hard to keep up on all this stuff. I did a quick search just now and found a couple of recent reviews of the literature that seem concerning— but don’t have time to dig into that at the moment. May pass some of that on at some point if it makes sense.
