Fentanyl is actually much more toxic than the mycotoxins produced by mold (which I'm guessing is what you're referring to), and yet fentanyl is generally recognized to be a useful drug because of its therapeutic effects. If something has no possible therapeutic, recreational, nutritional, or culinary effect, while being toxic, it might be fair to characterize it as a 'pure poison'.
That's a good definition. Still, you can take it literally - anything small enough doesn't really harm you. and meanings can be stretched to support whatever conclusions you want.
we used to think electrons were the smallest particles, until they were not.
and I think talking about breaking molecular bonds though or bringing "fundamental forces" into this is misleading and disingenuous. the point of the OP is to say, "you can take anything in a small enough dose and its not poisonous"
And when you say prions or whatever like you were, my point is if you take small enough doses even of those, you won't be poisoned. you get what I mean, so lets not waste each others time on trying to confuse impossibilities with reality. you won't be getting hurt or die or meaningfully poisoned by ingesting one "prion" or particle of "strange matter". and now when you describe any "poison" with this model, say you ingest 1 particle of even a pure poison, you won't be getting hurt or die.
