No evidence of what? That second hand smoke is harmful? Are you on meth?

The studies don’t show that. They merely assert that, without the data to back it up.

"No, the science is wrong, and me, a childish person on a pseydoanonymous forum ASSERTING the science is wrong is more credible than the science they use to show their conclusions are backed up by the data. Oh and don't even try to get me to actually comment on what I think is wrong in the data, because I haven't even read it." - You

That’s absolutely an argument, and it’s not grasping at anything.

Yes, it is grasping. Because you're not even refuting that SHS is harmful, you're trying to assert that outdoors, there is no SHS, by trying to show concentrations measured. So implicitly, you're admitting that any SHS IS harmful, because of course you are, because we all know that to be true, lol.

And you still haven’t sent any proof.

My stomach can't take much more of this :DDD

See, you already ignored the studies when I only quote their conclusions and the most important parts of them. What on Earth are you gonna do when I paste the entire study here?

This is from this exact thread, 3 comments earlier:

#No level of smoking or exposure to secondhand smoke [SHS] is safe. Even at the lowest detectable levels of exposure, we could detect changes in gene expression within the cells lining the airways

https://tobaccoatlas.org/challenges/secondhand-smoke/

#It is widely recognized through scientific evidence that there is no safe level of exposure to SHS

“Widely recognised.”

Show me ANY STUDY WHATSOEVER that says that there is a SAFE level of second hand smoke. Please. I've been waiting and asking for several comments now. Oh and, a bit too ashamed to answer the comment where you talk about "you need to understand there's a huge bias with tobacco..." when I replied to it with this? https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3490543/

#Inventing Conflicts of Interest: A History of Tobacco Industry Tactics

By the early 1960s—despite categorical research findings indicating the harms of smoking—a significant “controversy” had arisen (at the behest of the tobacco industry) over the validity and meaning of these findings. Indeed, given the widespread acceptance of the conclusion, especially among those who had analyzed and evaluated the research most closely, the persistence of debate about the harms of smoking is a striking demonstration of the powerful impact of the tobacco industry's public relations campaign. The industry insistence, at the direction of Hill & Knowlton, on the notion of no proof and the need for more research was an inspired if cynical manipulation of the natural tendencies within science to encourage skepticism and seek more complete answers to important questions.

Completely unlike what you're doing, amirite? :DDDDDD That's what is so hilarious; you're using century old rhetoric. It's like arguing someone who's genuinely insistent that "reefer madness" is a thing :DDD

You haven't linked a single study of any sort. You just keep stomping your foot and saying "NYAAAH NO NO NO THEY'RE WRONG AND I DON'T NEED TO TELL YOU HOW THEY'RE WRONG THEY'RE JUST ANGRY AT SMOKERS NYAAAAH"
