I am dubious of all the claims that say something designed to kill organic life is safe because it just means "safe at X dose". Like there isn't a pesticide made where I could drink a tablespoon of it and be fine. It just doesn't present noticeable effects at tiny doses so it is labeled safe.

Like if I drank a 1/4 shot of Vodka every morning I wouldn't notice it at all, but I imagine it would have some impacts on my health over the long run.

Not to mention we might have 30+ chemicals/medications/additives/whatever all being consumed constantly at "safe levels" with no research into how they interact or accumulate.
